Now, it's my pleasure to turn over the call to HubSpot CEO and Chairman, Brian Halligan. Thanks, Chuck. Good afternoon, folks. Thank you for joining us today as we review HubSpot's fourth quarter and full year 2020 earnings results. I'm exceptionally proud of how the HubSpot team closed out the year. In Q4, we saw a nice re-acceleration in revenue growth of 35% year-over-year. During the quarter, we surpassed 100,000 customers, and in December, we crossed $1 billion in ARR. Two terrific milestones on which to end the year. What's behind this re-acceleration in growth? This unusual year opened up everyone's eyes to just how early we still are in the digital transformation of the economy. This is the trend we've been seeing for 14 years, and which sped up for obvious reasons this year. New startups we work with, well, they're born digital. Older scale-ups we work with, who may have only been partially online in the past, have begun to fully digitize their end-to-end experience. HubSpot has the ideal platform to enable all these companies to build delightful modern experiences for their customers. Another trend we've seen is the shift in the market's expectations for B2B software. People now expect it to work like the consumer software they use in their personal lives. Traditional enterprise CRMs are cobbled together through lots of acquisitions, and the resulting user experience, well, it's pretty rough. Our CRM, it's crafted internally with a consumer-like UI matched with a scalable enterprise back end. This approach is resonating very well in the marketplace. All of our products and all of our geographies performed well in Q4. In particular, we saw strong growth in our enterprise tier. This year, we did launches of our Marketing Hub Enterprise product, our CMS Hub Enterprise product, and our Sales Hub Enterprise product. These all did well individually in the market, but the thing that really stood out was the number of companies buying two or more of our hubs, taking advantage of having their entire go-to-market on one platform with one data model, one representation of their customer, and one user interface. We're super pleased that our unique approach was recognized just the other day when HubSpot was named the number two best global software seller according to user reviews on G2 Crowd. We were wedged right between Microsoft and Zoom. Much has changed about the relationship between companies and their customers this year, and so much opportunity still lies ahead. After a strong finish to the year, the team is more motivated than ever to help our customers create remarkable end-to-end customer experiences and grow better in 2021. With that, I'll hand it over to Kate. Thanks, Brian. Let's turn to our fourth quarter and full year financial results and our guidance for the first quarter and full year of 2021. Fourth quarter revenue growth re-accelerated to 32% year-over-year in constant currency, and 35% as reported. Q4 subscription revenue grew 36% year-over-year, while services revenue increased 9% year-over-year on an as reported basis. Full year 2020 revenue grew 30% in constant currency and 31% as reported. Full year subscription revenue grew 32%, while services revenue grew 5%. Again, both as reported. We saw strong demand across all of our hubs in Q4, resulting in a re-acceleration in new business growth, along with record customer dollar and net revenue retention rates. In Q4, we added 8,400 net customers, ending 2020 with nearly 104,000 total customers, up 42% year-over-year. Average subscription revenue per customer of nearly $9,800 was up slightly sequentially, but down a few points year-over-year. Domestic revenue grew 27% in Q4, while international revenue growth was 40% year-over-year in constant currency and 47% as reported. International revenue represented 44% of total revenue in Q4, up three points year-over-year. Deferred revenue as of the end of December was $317 million, a 35% increase year-over-year. Calculated billings was $309 million in Q4, growing 38% year-over-year in constant currency and 43% as reported. This re-acceleration in constant currency billings growth was driven by strong revenue performance and a positive mix shift toward professional and enterprise subscriptions in the quarter. The remainder of my comments will refer to non-GAAP measures. Fourth quarter and full year gross margins were 82%, flat year-over-year. Subscription gross margin was 85%, while services gross margin was negative 20%. Fourth quarter operating margin was 10%, up slightly compared to the same period a year ago as a result of our strong revenue performance in the quarter. Full year operating margin was 8%, flat year-over-year. We invested aggressively in our business over the last year to meet the significant demand for our products and drive innovation to fuel long-term growth. We plan to continue this investment approach in 2021. At the end of the fourth quarter, we had 4,225 employees, up 25% year-over-year. Net income in the fourth quarter was $20 million, or $0.40 per diluted share. Net income for the full year was $64 million, or $1.32 per diluted share. CapEx, including capitalized software development costs, was $15 million, or 6% of revenue for the fourth quarter, and $59 million, or 7% of revenue for the full year. Free cash flow in the fourth quarter was $46 million, or 18% of revenue, and $79 million, or 9% of revenue for the full year. Finally, our cash and marketable securities totaled $1.3 billion at the end of December. With that, let's dive into guidance for the first quarter and full year of 2021. For the first quarter, total revenue is expected to be in the range of $260 million-$265 million, up 32% year-over-year at the midpoint. Non-GAAP operating income is expected to be between $17 and $19 million. Non-GAAP diluted net income per share is expected to be between $0.28 and $0.30. This assumes 50.3 million fully diluted shares outstanding. For the full year of 2021, total revenue is expected to be in the range of $1.16 billion-$1.17 billion, up 32% year-over-year. Non-GAAP operating income is expected to be between $98 million and $102 million. Non-GAAP diluted net income per share is expected to be between $1.51 and $1.59. This assumes 50.7 million fully diluted shares outstanding. As you adjust your models, keep in mind the following. At current spot rates, we're forecasting an FX tailwind to as-reported revenue of four points in Q1 and three points for the full year. As many of you are aware, we will have some unusual year-over-year growth comparisons in 2021. With that in mind, I thought it would be helpful to provide some additional color on how we're thinking about the cadence of growth throughout 2021. We anticipate revenue growth of 35% in the first half of the year, followed by revenue growth of 30% in the second half of the year as comparisons become more difficult. Our 2021 guidance assumes flat operating margins year-over-year. Embedded in that guidance, we have assumed a healthy level of investment across the business to meet the market demand we're seeing, more normal levels of T&E expense in the back half of the year, and continued strong investment in R&D. Lastly, we expect CapEx as a percentage of revenue to be about 5% in 2021 and free cash flow to be about $130 million, with seasonally stronger free cash flow in Q1 and Q4. With that, I'll hand the call back over to Brian for his closing comments. Thanks, Kate. Those numbers reflect how nicely our customer flywheel is spinning. Well, our employee flywheel is spinning nicely too. We were just recognized as the fourth best place to work in 2021 by Glassdoor. Last month, Comparably also highlighted HubSpot as being the number one best workplace for women and a top place to work for parents. We endeavor not just to talk the talk on diversity and inclusion, but walk the walk. We have a variety of initiatives underway, but two new ones I'm particularly proud of are our $20 million commitment to social impact investing and a new partnership with Howard University, which established a new center for digital business on their campus. The difficult years are always the ones that define you. I'm grateful to every HubSpotter in our partner community for the way we all pulled together to end the year strong and start 2021 with momentum. I'm super grateful to the 100,000 customers who put their trust in us. Thank you for your time. Operator, let's open up the call for a few questions. As a reminder, to ask a question, you will need to press star one on your telephone. To withdraw your question, press the pound or hash key. Please stand by while we compile the Q&A roster. Your first question comes from Mark Murphy from JP Morgan. Thank you, congrats on a great finish to the year. Brian, I had noticed what you pointed out that G2 Crowd had ranked Microsoft, HubSpot, and Zoom as the top three software companies for 2021. I thought that was pretty amazing. I'm wondering when we see that kind of prioritization that you're getting, should we assume that marketing budgets are going to shift pretty quickly to digital and to inbound this year? Is that embedded in your assumption, or do you see those signs? Is it more to do with the surge you've had in the starter cohorts and maybe we're going to see that converting this year? Hey, Mark. Thanks for your question. I was super pleased to see that sandwiched between two terrific software companies, Zoom and Microsoft. I think it's just a reflection of a lot of the bets we've made over the last couple of years. The product's just gotten way better. Our customers are way happier, and they're giving us really good reviews there on G2. Really happy about it. In terms of the second part of your question, things are good. We're seeing nice momentum across all three tiers of the product, the enterprise, the pro, and the starter, and across all the geographies. Feeling good. Things are going really well. Thanks for your question. I had a quick follow-up for Kate. I was just wondering if you see much of a structural change for your real estate costs and your T&E levels in the post-pandemic world. I think you said in the second half that T&E will normalize a bit. If you have more people working a bit more remotely, is it possible there's an extra point or two of margin coming out the other side of this, or do you prefer to reinvest that? Well, I think the theme that you will hear over and over from us is that we believe there's a ton of opportunity ahead and that we're going to continue to reinvest in the business. That's the comment that I would make generally. We are, as you pointed out, assuming that we are largely remote, at least for the first half of the year. There are some modest assumptions that we get back to travel at some point over the course of 2021. It doesn't have a dramatic impact on our operating margins for the year. Thank you. Your next question comes from Samad Samana from Jefferies. Hi, good evening. Congrats on this very strong finish to the year. Kate, maybe one for you and then one for Brian. First, Brian mentioned crossing the billion-dollar ARR mark, and that implies a pretty significant acceleration, I think, in back-half bookings, especially in the fourth quarter. Can you help us maybe understand how net retention looked and how that impacted it versus new customer bookings? Yeah. I think the good news is that we had great things to say about both of those pieces. In terms of retention, I obviously shared in the prepared remarks that we had a record quarter for retention, and what I like about that is actually there's just a lot of components that are all complementary and driving the retention in a positive direction. It starts with the fact that we had record customer dollar retention, and then our upgrade rates are also hitting new and record levels. In particular, we're seeing some strength in that edition upgrade motion. Yeah, I'll just add to that. Some of the investments we made are really paying off, and this is a leading indicator, but our Net Promoter Score is something we've been obsessed about for a couple of years, and this past year, it went way up. The investments we made are really paying off. Graduation rates. Typically, somebody's like a 300-person company that's been with us since they're 30, and they're heading to 3,000, a lot of times you graduate there. I just think the power we've added to the platform is really paying off, and people are sticking around longer and enjoying the new sophisticated features we're putting out. Brian, that brings me to a good follow-up question, and the ones I had for you was, crossing the $1 billion market is obviously incredibly impressive, but as you think looking forward to going from one to two and the flywheel that you have today, are there any changes we should anticipate or that you think that need to be made, or is it currently constructive? Can it get you to that $1.5 billion, $2 billion level, just as we think about investments in 2021 positioning you for that? When I think of HubSpot, Samad, it's like the bottom of the second inning in our baseball game. It still feels early. There is a giant market out there for CRM. We're mid-transition from moving as a company from being a marketing app to trying to become the number one CRM for scaling companies. You're going to see us continue to improve the product, improve the go-to-market, improve the way we execute. We're tireless in our desire to get better and to deliver more value to our customers. This isn't a steady state kind of company. A lot more investment coming, a lot more innovation, more products, existing products going to get better. It still feels early in my head, my friend. Great. Well, we wish you ongoing success, and it's great to see everything paying off. Thanks again. Yep. Your next question comes from Stan Zlotsky from Morgan Stanley. Perfect. Thank you so much. Congratulations also on a very strong end to 2020. Maybe just a couple of questions from my end. On the macro, what are you guys seeing across the world, and how are you baking that into the growth acceleration that you provided for 2021 on the top line? You want me to take that, or you want to take that, Kate? You want to start, and then I can talk about how we included that in guidance? Sure. I just sort of reiterate what I kind of talked about earlier, Stan, where there's a couple of drivers going on here. COVID just sort of accelerated people's digitization moves. I think everybody knew they needed to completely digitize their go-to-market. This just sort of accelerated it. The demand's been strong. I don't see that demand going back. I feel like people are going to lean into the future going forward. The demand's strong. The whole market is growing. Our target market is also expanding, if you think about it, like we're moving from a marketing app to a CRM platform. That CRM market is much bigger than the marketing app market. We're starting to do really well and make a lot of progress on there. The market is large and growing, we're just kind of really well positioned to lean into it. I also would just say, Stan, our competitive positioning is super unique and super compelling for prospects and customers. Our win rates are going up, and our retention rates are going up. Things are really good. Some of those bets we've been making over the last couple of years we've been talking about, they're really starting to pay off for us over the last year. Okay, perfect. Just a quick follow-up. The starter package promotion, which was a very smart strategic decision to make through the year, and the promotional pricing there, how are you guys thinking about that as you get into 2021 and some of the promotional pricing is going to start rolling off? What kind of retention and conversion rates are you guys thinking about? Yeah. Thanks for the question. We obviously are paying a ton of attention. I would say, just stepping back on that one, what we tried to do in making the changes on the pricing and packaging side there was to just simplify things. By bringing it together as a suite, putting forward a $50 price point, it just really simplified the buying process at the low end, and the learning that we have there is that making it easy is super compelling. We think that was a great choice to make. We have been watching the upgrade rates closely. We have been watching the usage rates closely, and we're feeling good about both of those metrics. Overall, we're feeling great about that Starter Growth Suite play. We do have operational plans underway to try to maximize success on the renewal of those big cohorts, and so we will continue to share that as appropriate. Perfect. Thank you so much. Congratulations on a very strong quarter. Thank you. Bye. Your next question comes from Terry Tillman from Truist Securities. Hey, this is actually Nick on for Terry. Thanks for taking our question. Just wanted to touch on international a little bit. It seems like international revenue growth has actually continued to outpace domestic growth in recent quarters. I was just wondering if you guys could talk about how you're investing in that area to continue to drive strong growth, where international could potentially move to as a percentage of revenue longer term. Thanks. Sure. This is Brian, Nick. I can take that. Frankly, I'm really happy with both the international growth and the domestic growth. Domestic growth really ticked up nicely. I think it's just a testament to the market is quite big, and I think it's growing. Now, when you look at the market, U.S. versus international, really all our segments are doing well. Across the geography, small business, the mid-market, and the enterprise segment are doing well, and then both our channels seem to be doing well. Our direct channel and our indirect channel, our partner channels seem to be doing well, and I think it's just a reflection that the product's gotten better, the value prop's getting better. Our flywheel's spinning really nicely. Maybe Kate's got something to add to that. Yeah, I think that as we look at international, it has consistently been stepping up as a larger share of the overall revenue of the company, and we would expect that that would continue over the next few years. Your next question comes from Arjun Bhatia from William Blair. Hey, thank you, and I'll add my congrats on a strong quarter. Brian, maybe one for you. You've touched on kind of this evolution from an app to a platform. I'd just love to hear what you're seeing from your new customers in terms of product adoption. Are you seeing them actually buy the whole platform upfront, meaning the Growth Suite, get all three solutions, regardless of the edition that they're starting on? Do you see more platform adoption from these new customers that are coming on board? Arjun, great question. The transition is going real well. When I think about HubSpot, I can't help but think about the Clydesdale rule. I'm not sure if you're familiar with that. If you have one Clydesdale that can pull GBP 1,000, then you add a second Clydesdale that can pull GBP 1,000, the really interesting thing that happens is that combined Clydesdales can pull GBP 4,000 worth of stuff. That's HubSpot. We have our Marketing Hub, we have our Sales Hub, our Service Hub, our CMS Hub. They're all built on this set of shared services underneath. The UI is the same. There's a single data model. It's a beautiful consumer-like front end and a powerful enterprise back end. We're seeing nice adoption of that, a nice pickup from new customers who are buying a full suite, particularly the starter suite, and lots of existing customers who are Marketing Hub or Sales Hub buying other hubs. Getting really good traction on it, particularly with new customers, but also the installed base. Perfect. Thank you. One follow-up, if I can, for Kate. I think you mentioned really high record net retention rates. As we look forward, I think this has fluctuated in the past, do you get the sense that we're in a place now with the expansion motion that this can consistently stay above 100%, or should we expect a little bit more fluctuation there going forward? Yeah. That's the question we spend a lot of time talking about internally as well. I think, you just kind of turn the clock back a little bit. At the time of the IPO, we had sort of a net retention in the mid-90s. Over the last couple of years, that has stepped up and we've been staying in and around 100. I think we've reached a new gear here in the last couple of quarters. We're not calling a new normal, but the performance over the last couple of quarters certainly gives me a lot of confidence that we'll be able to keep retention at or above 100. Perfect. Thank you very much, and congrats again. Your next question comes from DJ Hynes from Canaccord Genuity. Hey, thanks. Congrats on all the accolades and momentum. Really impressive stuff here. Brian, I got a product question for you. If you think about HubSpot in the context of a CDP, right, collecting the data across the various customer touchpoints, my sense is that you guys are really good at aggregating the data that happens inside of HubSpot. Where are you in terms of pulling in data that's generated in other systems? Is that something that customers ask for? Is it important to the growth of the platform? Any color there would be helpful. Excellent question, DJ. Excellent question. I do think of HubSpot as a CDP, where we do a fantastic job of collecting all kinds of data about all the touchpoints you have with your prospects and customers, whether that's visits to your website, or they fill out a form, or they're chatting with you on the website, or they have a call with your sales rep, whether they fill out a ticket, whatever it would be. Then we combine them together and have this one unified view of the customer that makes it incredibly valuable for the whole organization. Where you'll see us go over time is getting better and better, not just with collecting that data that is managed by HubSpot, but with all of your front office applications and pulling all that together and making sense for our prospects with it. That's an area we're investing in, super excited about, our customers want it, and keep your eyes on that channel. Okay, awesome. One follow-up from Kate, if I can. Really strong net adds the last few quarters, but I think equally impressive is that ASRPC has been going up sequentially, right? Do you think we've seen a bottom in that metric? Is it possible that we see subscription revenue per customer actually grow in 2021? Yeah. Again, we're hitting in on all the really hard ones here. Yeah, we were obviously very excited about the incremental net adds in Q4. I think the thing that I liked about it, which seems like we're aligned on, is that the customer growth was very balanced across the starter and the professional enterprise, and so it translated also into a quarter-over-quarter increase in ASRPC. Honestly, you're going to see some quarters where you have less customer adds and they're going to be at the high end, and you're going to see bigger increases in ASRPC. You're going to see other quarters where you have a concentration of the customer additions at the low end and a little bit more pressure in ASRPC. The good news is that when we look at the starter and we look at professional and enterprise, each of those is expanding, and so we feel good. Yeah. Okay, great. Thanks for the color, guys. Congrats. Thanks. Your next question comes from Brian Peterson from Raymond James. Thanks for taking the question, and I'll echo my congratulations. Brian, maybe just one for you. If I think specifically about Sales Hub, in some of my partner conversations, I've heard that the ability to kind of work with larger and larger teams is something that's kind of a common theme. What are some of your largest deployments for Sales Hub, and how large do you think they could ultimately be over the next three to five years? Brian, thanks for the question. Sales Hub has a ton of potential. We re-released Sales Hub Enterprise at INBOUND last year. We've had very strong demand for it over the last few months. We have a whole bunch of good stuff teed up for Sales Hub Enterprise this year and next. That product's going to get very legit. Very bullish on the future of that product. In terms of the sizes, we're definitely closing bigger deals. We closed a couple of whoppers in Q4 with many hundreds of seats. We just see a lot more deals in our pipeline with larger seat volumes. The strategy and the investments are starting to pay off there on Sales Hub, where the deal sizes are getting big. One of the things we've just been working on, like if I think of HubSpot, I step back and think about it, we're really strong in the very middle of the market, like 20 - 200 employees, and I give us like an A+ on our product market fit, our go-to-market market fit in there. Where we're working hard on is that 200 - 2,000, what we call the enterprise, and then the 2- 20. Lots of investments going in last year and this year in those areas. We think we're going to make a lot of progress there. Good to hear. Thanks, Brian. Your next question comes from Michael Turrin from Wells Fargo Securities. Hey there. Thank you and good afternoon. The initial guide on top line for the upcoming year really stands out. You've laid out a bunch of reasons for it, anything else you can add? If I'm looking at this right, haven't initially guided to 30%+ revenue growth in four years now. Anything you'd call out that's just structurally different heading into this year versus prior years? I hear Bezos talk about this, but in the given quarter, the stuff that's happening now is stuff that we've made really over the last couple of years. Like what happens this month doesn't really impact Q1 that much. I'm not shocked that we're seeing such good results, and we have such good guidance, and we've re-accelerated. In a couple of cases, we're really done, like, the two steps back so we could take four steps forward, and we're just getting a return on some of those bets. Our market's bigger. We moved from a marketing app market, which is a cool market, and not small and growing, to your whole darn front office. The CRM market is much, much bigger, and everyone needs one. It's not an optional thing. Whether you're a startup buying your first one, or you're a scale-up, and you're not happy with what you've got, we're just a great fit these days. We've become a better fit over the last couple of years. Our competitive advantages have increased. It's a little bit boring and a little old school. Our value proposition has gotten better. We win more deals. We retain customers longer. We delight our customers. It's a little bit of very old-fashioned. It works. Long-term vision is neither boring nor old-fashioned. It's refreshing to hear. The other question we've just been getting a lot is around new customer trends and how to think about the sustainability of these elevated levels. Has the Starter Growth Suite unlocked something new you feel you can continue to tap into here? Anything else you can provide just to help us think through comparing the net adds you've seen this year versus prior historical periods? Yeah, it definitely feels like we've sort of hit a new level. You've seen now three quarters where you've have broken away from that, what we had been at that, call it 3,000, 4,000 customer adds per quarter. We feel good about our ability to continue to operate at that new level. Now, that doesn't mean that I would translate it into 8,000-9,000 a quarter. I do think, as I was talking about a little bit earlier, there'll be some variability from one quarter to the next, based on whether we're seeing some strength at the low end or strength at the high end. Thank you. Congrats on the results here. It's truly impressive. Thank you. Your next question comes from Drew Foster from Citi. Hey, guys. Thanks for taking the question. Brian, you've been talking a lot about the growth and evolution of your portfolio to more of a front-office platform. I'm just curious what you're seeing as sort of the biggest changes in that market more broadly in the context of how that changes your view of different areas that look like attractive adjacencies for your portfolio. Yeah. That's a good question. If I sort of back up and think about it, I've been in this world of CRM literally since 1990, when I graduated college. Many times over my career, I was in the position of either buying and implementing or using a CRM. There's the tried and true playbook for how you do this, and it's been around for a long time, where someone builds an SFA application, and then they buy a whole bunch of stuff and cobble together this giant FrankenCRM. We're seeing there's several of them in the market today, and it's a good way to build a business. We decided to kind of zag when everyone else was zigging on that playbook, and we decided instead of cobbling this thing together, let's craft it, sort of Apple style, and make it a beautiful application. Our development team, our product designers, our user research people are really good. The tools that we use and the platform we use internally is so powerful. We've decided to build it, and we think it's unique and differentiated, and it really matters to the end users and the ops people who implement this stuff. Given that, underneath HubSpot, we have this set of shared services, and we've exposed them through four hubs today, but we aren't done. It's still pretty early innings for HubSpot. There's a lot more stuff in our heads and on our drawing boards that we can expose through additional hubs down the road. I'm not going to show my hand at when those hubs are coming or what they are, but we're not done. There's more opportunity out there for HubSpot. Still early innings. Got it. Okay. Now that your newer Hubs have been out in the wild for a few quarters, especially some of your Enterprise releases, just wondering if you could give some anecdotes about sort of the role they're playing as new front doors to your business, as you've talked about in the past, whether you're attracting new types of customers, just given how strong that customer number is the last couple of quarters here, some color will be helpful. Thank you. Yeah. Thanks for the question, Drew. I kind of think of HubSpot as we have Marketing Hub, which is the OG hub, going really well, growing fast at scale. A big market we're going to continue to grow. You got Sales Hub. Good-sized business now. Wow, is it growing fast. Lots of opportunity there. You get CMS Hub and the Service Hub. Those hubs to me look a lot like the Sales Hub looked two, three years into that evolution. Hopefully, three years from now, we have Marketing Hub and Sales Hub both at scale, and then these two hubs are cranking, are big businesses, and then there's new hubs kind of coming along. It's sort of like horizon theory. There's horizon theories, one horizon, one bets, horizon two bets, horizon three bets. We have sort of bets along those horizons, and they're maturing at different rates of new bets that will come online. The new hubs are doing well. CMS Hub and Service Hub doing well, remind me a lot of Sales Hub. I think they'll be big businesses. The Clydesdale combination of these things is going to be really powerful over time. Awesome. Thank you. Your next question comes from Christopher Merwin from Goldman Sachs. Hey, thanks a lot for taking my question. I wanted to ask about the service space. We're hearing more and more about messaging and chat bots being central in engaging with current and prospective customers. Can you talk a bit about what you're doing in that area and how you're capturing that data and helping reps close more deals? Yeah. We're super interested and we're investing heavily in that. If you take a step back, you think about most of the communication that happens with asynchronous is email, then just increasingly people want to do synchronous messaging types of communication. That comes to life through lots and lots of different ways these days, lots of ways to message. The one you're talking about, sort of chat on the website and building bots that automate that chat, that's an area we've invested a lot in, and we have a great offering in the market today that our customers are buying. It works on your website. If you've got an app, it'll work inside your app. All of that gets pulled into a central place, and people can respond to those in real time. That's an area we're super excited about. That's an area of growth for HubSpot. That's an area where human behavior is changing, and I think HubSpot's quite good at staying on top of those changes and helping people deal with them. It's a great question. We're really excited about that space. Great. Thank you. Maybe just a quick follow-up. Obviously, I think you talked about it a little bit before, but accelerating growth next year, not going to see that pass through to margin, but yes, you're investing a lot in the long term here. Is it possible to get a bit more granular on some of those key areas, specifically within go-to market, and R&D? Thanks. Sure. We've been investing relatively heavily in R&D over the last several years, and we're going to continue to do it. We feel like we're getting nice returns on it, showing up in the retention rates, Net Promoter Score, revenue growth. The leading indicators look good, the lagging indicators look good too. We're going to keep investing there. We're going to invest in their existing products. You saw we have a playbook where we can go into an existing product, a hub, and kind of relaunch it, really go after it again, and that works really well for us. We'll build some new hubs and new capabilities. Our R&D team is kind of on fire these days, we're going to continue investing in those folks. Kate, do you want to add anything to that? No, I think on the go-to-market side, we continue to invest to be able to service the demand that we're seeing in the market. I think we talked about the fact that we feel like we have this A on the go-to-market and product in the middle, and that we're investing both up-market and also in tech-touch at the low end. Great. Thank you very much. Your next question comes from Ken Wong from Guggenheim Partners. Great. Thanks for taking my question. Brian, you mentioned earlier CMS and Service looks like we're two, three years into what you saw with Sales. We think about the kind of the maturity of those products, is it just a matter of time, you think, before we get to a run rate like Sales? Or is there some incremental watering, seeding, loving that you guys have to give to Service Hub from a product go-to-market perspective before we maybe see those kind of results? No, lots of watering, lots of fertilizing, lots of work left to do. Let's just pick out Service Hub. The product is terrific, let's say if you're a 50, 75-person company. If you're a 500 or 750-person company, there's some stuff that's still missing, and it kind of reminds me of Sales Hub a couple of years ago. If you're a 500, 750-person company, you're close, guys, but there's a couple of gaps. It's very similar. We know what the gaps are, and in our own way, leveraging the primary colors, we're filling those gaps. There's plenty of water, plenty of fertilizing left to do. I would say that also for the Marketing Hub product. We've had that product out there for 14 and a half years. There's still plenty of low-hanging fruit on that Marketing Hub product. It's a terrific product. Even this year, it's going to get a lot better. Yeah, we don't see HubSpot as sort of this fixed thing. There's going to be a lot of innovation across new and existing hubs over time. Got it. Great. Kate, just on the margins, so second year in a row that we've had flat margins, and I fully recognize it's a fantastic time to step on the gas given what we're seeing. I guess, as we think going ahead, should we think that you guys are more focused on the growth side versus the margin side, in terms of how we should kind of adjust our models? Yeah, I think that the message that you should hear from us is that the priority is on continuing to invest in the business to drive long-term growth. That said, we have a framework. Over the long term, we will continue to follow that framework. In the near term, I think you shouldn't expect a linear movement. Got it. Perfect. Thanks a lot. Your next question comes from Michael Turits from KeyBanc Capital Markets. Hey, guys. Thanks for taking my question. A strong quarter both on the net expansion of existing customers, and it sounds like new customers came in at a high price level too. Which was the bigger factor, in both of those? Was it the edition upsell and higher level of editions, or was it more attach of multiple hubs? It's relatively balanced. Across those factors, there's a bunch of stuff that plays into it. Yeah. I would just say new and cross-sell both perform well. Kate, last quarter, you made a comment about billings in terms of duration, that there was a duration headwind. This quarter's a strong billings quarter. Was there a duration tailwind in any sense this quarter? Yes. There was. I think as many people who listen to these calls would probably know, billings is not my favorite metric out there. There's just a lot of stuff that happens with billings that can confuse people. That said, again, over the long term, constant currency revenue and constant currency billings are going to track one another. You see quarter-over-quarter, some volatility there. By the way, I'm getting seven packages delivered, so I apologize for the beeping in the background here. I don't know how to shut it off. Last quarter, we did see constant currency billings above constant currency revenue. A few points of that is a result of the fact that we're getting some advantage from a duration extension. The professional and enterprise editions performed really well, and those tend to have longer billing terms than the lower-end starter products. There was another small bit here that was helpful. Some of the customers that we had given short-term plays to, in Q2 at the onset of the pandemic, were coming off of those sort of discounts or flexible payment terms. They billed again in Q4. It was a smaller factor. The remaining is really just strong bookings for the quarter. Great. Kate, do you want to get the doorbell? I'll take the next one. Good God, sorry. I apologize. I'll get the next one. Your next question comes from Ryan MacDonald from Needham. Okay. Hey, this is Alex on for Ryan. Could you discuss the strategic rationale for The Hustle acquisition? Content creation and top-of-funnel lead generation has never really been an issue for the business, in my view. How does this enhance the business or HubSpot's ability to acquire new logos? Great question, Alex. When we started HubSpot, it was on this idea of inbound marketing, the problem with marketers is they're always renting space on someone else's asset, a radio show, a TV show, a newspaper, and increasingly more recently, a social network or a search engine. The idea behind inbound marketing was instead of renting space on somebody else's asset, let's just create your own asset, increase the number of those assets, and increase the return you're getting on those assets. What I love about The Hustle folks is they had some unbelievable assets. They had a newsletter asset, very modern and new newsletter. Those things are taking off. They have the best one in the business right now. They have a fantastic podcast and very deep research. It's a little bit of an acquihire to get that terrific talent and all those assets that we plan to invest in and grow over time. We're super excited about The Hustle. We think it's going to give us an unfair advantage on the marketing side for sure. Your next question comes from Jennifer Lowe from UBS. Great. Thank you. Brian, you made comments a couple times about sort of the scale-up versus startup components of your business, and in particular, given that a lot of those companies that may have been in market longer are now dealing with a selling environment that's very different than how they sold in the past. I'm just curious if you're seeing any difference, and at the same time, you've matured your own product with the enterprise and pro SKUs. Are you seeing a difference in how often you're replacing an existing technology that may not be meeting current needs, as opposed to how frequently you're landing in an environment where there just really isn't pre-existing technology? Yeah. That's a terrific question, Jennifer. In a startup, we're typically the first legit system they have in place, like the first legit CRM they'll put in place, which is where we want to be, and then we want to scale with them. In a scale-up, oftentimes someone has tried to put in a CRM, and it just didn't go well. It was too hard to set up, or it was too hard to use, and it was too complicated. They got it sort of partly set up, and then they just said, "There's got to be a better way to do this stuff." They find HubSpot, and they implement us, and that's starting to happen more and more. We've been talking about that for a while, but we're starting to see more of that in the market. I think it's a testament to our approach. It's a patient person's approach to build all this stuff, but I think that patience is paying off. I also think our go-to-market, Jennifer, really helps us in that area where to engage with one of those traditional CRM players and you get into a free trial, it's not freemium. You got to deal with a whole bunch of sales reps to get anything done, and we've got a super modern approach to the way people do it, and I think people like it. They want to use a free product and give it a run. They want to try it. They want a trial, and yeah, they want to talk to a sales rep and engage and learn about it and pricing and packaging and negotiating and helping them get it set up. I think our approach to letting people really use it matches the way they buy. I also think it really highlights our strength, that it is easy to use and set up. It's very modern. I think HubSpot's a little bit like Zoom. Zoom's not only a better product, but their go-to-market is much lighter. It's much easier to buy. We want to be more like that. I think that's the future of SaaS. It's more like that. Okay. Just maybe a more specific one. It seems like relative to the headwinds that were happening in Q2 when everything went to shelter in place, you've now largely kind of recovered some of the business that was negatively impacted by that. Is that a fair assessment, or is there still more opportunity to improve on the recapture rate of business that might have been impaired earlier in 2020? We are largely through the impact of our COVID plays. Okay. Thank you. That's it. Your next question comes from Keith Bachman from BMO. Hi. Thank you. I'll ask two, if I could, and I'll just do it concurrently. One is, you talked about net adds, in particular to follow on Michael Turits' question. I just want to hear some comments about this calendar year. Is there anything you want to call out in particular? Just trying to understand how you think mix for net adds may have an impact on the model. The second question is, in the past, you've talked a little bit about commerce could be an opportunity for a market, and just wanted to hear some thoughts, any updated thoughts on commerce in particular, what the opportunity might be for HubSpot in terms of your differentiated model. Thank you. Why don't you take the first one? I'll take the second one, Kate. Sure. In terms of new customer adds, I think what you saw this year, 2020, was that the initial step-up that we saw in Q2 and then into Q3 was very much associated with the Starter Growth Suite pricing and packaging change. Over the course of Q3 into Q4, what we saw is a much more balanced set of customer additions, which is what sort of leads me to the comments that from one quarter to the next, there's going to be some difference in the kinds of customers we add as we introduce different functionality and make pricing and packaging changes. Keith, on your commerce question, we've largely focused on B2B. I kind of think of Shopify and HubSpot. They're the B2C side, and we're the B2B side. We do think there's opportunity, though, increasingly on the B2B side. The way people want to buy, it's changing, and increasingly, they want a very light touch experience. Increasingly, they want parts of their products and maybe all of their products, even on the B2B side, to be some sort of an e-commerce transaction. That's an area we're very interested, and I'll just leave it at that, very interested in. We're investigating and looking at. B2B commerce is, I think, a nice area of opportunity for startups and companies like HubSpot over the next several years. The B2B buying process inevitably is going to change, and I think it'll change for the better for the vendors and the buyers, and we want to be able to help our customers with that over time. Okay, great. Many thanks. Your next question comes from Kirk Materne from Evercore ISI. Great. Thanks very much for fitting me in. Congrats on the results. Brian, you touched upon this in some of your prior comments. I was just kind of curious how often the concept of a platform now comes up with both, really new customers, meaning everybody's moving faster from a digital perspective. As they move faster, are they asking more about sort of, I want to make a bet on a platform as my first landing spot versus what you have saw maybe a year or two ago? I think we can all see the customer adoption that you guys are seeing is accelerating. I was kind of curious if the conversations you're having around that platform are also changing at maybe the same pace. I think they are. Increasingly, people are coming to us and buying the whole platform up front, just a lot of people who are Marketing Hub customers who are maybe looking at a new CRM. It's kind of a no-brainer to buy HubSpot. They already know how to use the platform. It's a single view of the customer. It's kind of a no-brainer. It comes up more and more, people wanting to buy the whole solutions coming up more and more. Some of the investments we made over the last few years are paying off. I would just add, Kirk, that we have a ton more work to do on it. I look at our platform as we've made tremendous progress over the last couple of years. When I talk to customers, there's plenty of low-hanging fruit for us on the platform side and plenty of things they still want us to do. We got a lot of work left to do on it. Okay, great. Thanks very much. Your next question comes from Siti Panigrahi from Mizuho. Thanks for taking my question, and congratulations. Going back to some earlier question about this, you talked about positive mix shift to Professional and Enterprise. Last year, after the pandemic broke, you talked about downgrades of subscription. How much of this mix shift influenced by those customers upgrading back versus this newer starter customer that joined last couple of quarters now upgrading into more Enterprise and Professional? Have you already upgraded most of them who downgraded right after March, April? I would say, let me parse this into a couple of things. You are absolutely right. We gave a number of concessions, or we gave a set of concessions to customers in Q2 as part of the initial reaction to the pandemic. Most of those took the form of short-term discounts and flexible payments. We are through the majority. We are through most of those, there is some impact in Q4. It's not huge. The bigger impact on the duration, it comes from the set of new customers that we're adding, where we're seeing more strength in that professional and enterprise tier. Your next question comes from Derrick Wood, from Cowen. Great. Thanks for taking my question and congrats again on a strong quarter. I wanted to come back to the notion of shifting from a marketing app to a CRM platform, and clearly that's gaining momentum, but I wanted to maybe ask about what's going on in the channel and whether existing partners are kind of evolving towards more of that broader platform approach as well, or perhaps there's a new kind of cohort coming on board from the partner side. It would be nice to hear about how you're seeing the channel evolve. That's an excellent question. Thank you. The channel's definitely evolving. When we first started HubSpot, it was a marketing agency partner channel. I even think we called it the agency partner channel. We call it a solution partner channel now because they are solution partners. There's two things going on. Some of those marketing agencies just want to do marketing. They're born marketers, they just like marketing, and they work in Marketing Hub, and they've got a terrific business and they're not changing. Some of those marketing agencies, though, are shifting to be much more of a CRM partner for their customers and have really shifted the way their business model works and their value prop works. We're thrilled to see both of those, frankly. If we look at the mix of new partners coming in, we definitely still have marketing agency-style partners coming in, but increasingly, it's CRM implementers. It's a little bit more technical of a partner doing a little bit of a bigger implementation, more integration, more customization. It's a little bit of both. Where I think the opportunity is going to be amazing is when people can use our content management system and our CRM system, combine those things together to create awesome experiences for their customers. There's a lot of opportunity for partners there. Great. Thanks for the color. That was our last question at this time. I will turn the call over to Brian Halligan, CEO and Chairman, for closing remarks. Thanks everybody for joining the call today. Thanks a lot. Appreciate you. Ladies and gentlemen, this concludes today's conference call. Thank you for participating. You may now disconnect.
