With that, I'd like to turn the call over to our Chief Executive Officer, Sarah Friar.

Thank you, Matt, and hello, everyone. We're delighted to be joining you for our first public company earnings call, having just successfully closed our merger with the Khosla Ventures SPAC. Our gross proceeds of $674 million, that's $404 million from the SPAC trust proceeds and $270 million from a fully committed pipe, will fund long-term growth at scale, enabling our purpose of cultivating a kinder world where everyone has a neighborhood to rely on. In Q3, we delivered strong revenue growth of 66% year-over-year and saw continued growth and engagement of our ecosystem at scale, with weekly active users, or WAU, increasing 20% year-over-year to 33 million. Nextdoor equals neighborhoods, and we own the local graph. We are nearly 1 in 3 households in the United States with 66 million verified neighbors globally, including 11 million in our international markets. In addition to our continued growth in reach, we are seeing sustained and increasing engagement. Nearly half of our users engage with Nextdoor weekly, and we know that when people come to Nextdoor, they stay. Our 3-month retention rate is over 75%. And even after 2 years, over half of our users remain engaged. As you know, this is well ahead of many of the other social media platforms. The past few quarters have further demonstrated how we've aggregated a range of local use cases that are increasingly turning Nextdoor into a daily habit. We see a continued trend towards local, which we believe is structural and sustainable. For example, according to our third quarter insights report, 73% of U.S. adults say that neighbors are the most important community in their lives. And neighbors are doubling down on their commitment to local with 72% making it more of a priority to support local businesses compared to before the pandemic. We…

Thank you, Sarah, and good afternoon, everyone. I'm pleased to report that we've had a strong third quarter. I'll start first with a summary of the headline numbers before diving into more detail from the quarter. In Q3, we saw continued growth in global engagement with 20% year-over-year growth in weekly active users. Total revenue was $53 million, which was an increase of 66% year-over-year and 15% quarter-over-quarter. Global ARPU grew 38% to an annualized rate of $6.46. On revenue, we saw strong performance across all advertising verticals, including home services, financial services and tech and telco. We're also excited by the early traction from newer verticals like CPG and travel and entertainment. Sarah mentioned Disney, and another example was our Q3 partnership with Airbnb to drive host acquisition in target cities. Across customers of all sizes, our expansion into new verticals have contributed to improved revenue diversity. Our brand is building in the market. In addition, revenue was driven by new accounts added, improved -- improving advertiser retention and existing advertisers increasing their spend over time. The key driver of our advertiser retention and new account additions is improving measurement capabilities. For example, we recently launched our own pixel and have seen more and more advertisers adopt it, better enabling us to demonstrate strong ROIs and increasing PBMs. ARPU growth of 38% year-over-year was driven by increasing engagement among weekly active users and efforts to better optimize our supply by driving higher fill rates and improving our direct relationships with advertisers. Outside the U.S., we are still very early in our monetization efforts, but we are encouraged by the initial trends, particularly in the U.K., where revenue nearly doubled year-over-year in Q3. This progress gives us confidence that the U.K. is paving [ a way ] for monetization rollout…

[Operator Instructions] The first question comes from Eric Sheridan with Goldman Sachs.

Maybe 2, if I can. Sarah, for you, would love to understand what your key learnings were coming out of the pandemic period? And how that informs product development as we turn into '22 and future years in terms of driving a mixture of user growth and engagement per user? And then on the long-term investment road map around the advertising business. Can you help us understand a little bit of what you see as some of the key unlocks to drive greater depth of advertisers and verticalization of advertisers on the platform in the years ahead?

Okay. Eric, thank you so much. These are great questions. So first on key learnings, so, what we saw during COVID is something that we've seen during other emergency situations where Nextdoor really becomes of the moment. As it happened in microcosm like Hurricane Harvey, we see it during California wildfires, we've seen it in the U.K. when the Grenfell Tower fell. The global pandemic just happens to be an emergency that happened across almost every neighborhood. So the good news is Nextdoor became incredibly useful in the moment for neighbors to get trusted information to give and get help and then ultimately, to create connections online, which post-pandemic they're taking offline. So one of the things that we saw is as people came to the platform, engagement across those newer cohorts have actually been enduring. And I think that's important. We think the platform just got better. People who haven't tried it for a while, came back and [indiscernible] people who have never tried it, came back and I think we're really impressed. So neighbors of those newer cohorts are about 2.2x more likely to post, 1.2x more likely to come than they were pre-COVID. And we think that's just because the platform itself has gotten better. Overall, in terms of learning. So for us, it's all about how do we take that increased engagement. So what are we doing to continue to bring neighbors back? So that's an investment in notifications. We're definitely a trigger-based platform, but we can do better and better with notifications by applying better data science and machine learning. The second thing that we learned is that people want to hear from all of the stakeholders in their neighborhood. So again, I gave out that top about 70 -- sorry, that stat, about 72%…

No.

The next question comes from Mark Mahaney with ISI.

Two questions, please. Sarah, you talked about these 3 initiatives in terms of solutions for advertisers and one of those is building out self-serve ad tools. What's the status of that? How far along have those self-serve ad tools been built out? And to the extent that they've been rolled out, what kind of reaction are you getting to them? So just double-click on that, please. The second one is on the MAU growth of that 20%, could you talk about what the growth was in your largest and most mature market, the U.S.? And whether that growth is what you want it to be or what are the things you need to do to accelerate that growth?

Great. Let me do the first question. So first of all, just on self-service tools. So it is a very important part of our longer-term strategy to get more self-serve available. But we're very early on that. Really can start as to alpha test in Q2 and getting a little further along in the journey in Q3. But I think self-serve will be something that is more applicable as you look at our 2022 results and our 2021. Let's talk about the why on self-serve? So to date, Nextdoor clearly can go from the largest advertisers and ad agencies in the world all the way down to the smallest of small businesses, whether like the dog-walker, maybe the baby-sitter. When you get into the mid-market and get into self-serve and clearly, what you want to see is the ability for people just to come to the platform, turn on their ad as fast as possible. So beyond even just self-serve, we want to make sure it's a couple of clicks and you're done. Because small businesses are on the go, they're busy, they need us to do the work for them. So that's really about the front-end part of the platform. And as I said, you'll see much more of that impact in 2022 than you'll see in 2021. I don't want to forget about the back-end part of the platform, which is really, I think of it as the brains of the operation. And that's a place where we're doing a lot of investment around data science and machine learning to make sure that we're using all the data that Nextdoor sits on top of [ what ] were a first-party, proprietary ad-based platform. So we have a lot of data and when used well, it takes an ad from being even an ad into a piece of content. So the right ad served at the right time to the right person actually satisfies the job they came to the platform for. Think about the plumber, right? If you suddenly have an incredibly leaky faucet on a Sunday night. And the plumber -- and you can find the plumber immediately on Nextdoor through an ad. That's actually an amazing piece of content. So it drives neighbor engagement as well as giving a really strong ROI for that advertiser. So we are investing in both the front-end, how people come and buy ads on the platform, but also the back-end to make sure that we become an incredibly performant platform. We are today, but we want to make that better and better over time. And then Mike?

Mark, this is Mike, and I'll take the second part of that question on WAU growth. So as we shared, we were up 20% year-on-year, around 33 million total WAU across the platform. In the U.S., we were in the high teens. And internationally, we were at around 40% year-on-year WAU growth.

The next question comes from Brian Nowak with Morgan Stanley.

This is Chloe on for Brian. We have 2 questions. The first would be if you could please talk to us a little bit more about your community level engagement metrics over time and what you might be able to share on time spent per user in your most developed communities compared to the newer communities? And then second, how does monetization and ad perhaps like the ad revenue per hour spent compared in your most developed communities versus those newer ones?

Okay. Let me -- I'll start with the question that you had about community level engagement metrics. So as you know, we measure engagement through WAUs, and that's what we've talked about today on the call, about 20% year-over-year growth. We're quite proud of because it actually builds on a very active period of time last year during COVID. And as you've seen, Chloe, many platforms actually started to see a little bit of a downtick as we came into this period because of tough comps. We've actually been building and seeing kind of our highest level of WAUs ever. Beyond that, we do internally tick down into looking at insights on different segments. So we use that to inform product decisions. But we changed those over time, just depending on where we see shifts happen. The reason why we focus so much on WAUs is that once we get someone to be a weekly active user, their propensity to become a daily active is quite high. And we already see for weekly active users, they come on average about 4x per week to the platform. But let me lift up a little on your kind of where you're going with that thought about time spent in app. Nextdoor is a little different from maybe other social platforms that might air more towards entertainment rather than utility. So we think there's 2 modes of engagement on Nextdoor. There's, of course, the community piece, which is vital, right? We're not going to cultivate a kinder world where everyone's in the neighborhood to rely on, the thought-building community. But the second piece is utility. And that's, again, where Nextdoor tends to spike. If I go to utility first, utility is not really well measured in terms of time and app. Because actually,…

Yes, I'll take the second part of that question on monetization by neighborhood. As just a reminder, we're still very early to monetization, and we find that there's more commonality amongst advertisers than differences in how they are pricing getting value on the platform. Broadly, they're looking for reach and also the ability to drive frequency of their messaging in a targeted way in neighborhoods. So for us, the most important thing is showing penetration and engagement, giving them more of the unique supply that they're after and then taking into consideration the targeting and objectives of the campaigns. With that in mind, the monetization looks similar across neighborhoods that are similar in penetration and engagement. And so we don't [ see ] a metric where we're sharing sort of difference in revenue per hour spend for some of the reasons that Sarah mentioned. For us, the most important thing is delivering that reach and engagements to advertisers, helping them to best use the first-party data on the platform to target their message. And then to -- given the measurement tools that they're after to demonstrate the results of the spend in our neighborhoods.

[Operator Instructions] There are no additional questions waiting at this time. I will now turn the call back to Matt Anderson.

Thank you, Aaron. So since we're at the end of our live question queue, we recognize that over the last quarter, we had the opportunity to engage with a number of folks in the audience today. We've detailed a number of the questions in our Investor Day and our Analyst Day, both of which can be found on our Investor Relations website, if you'd like to [ read them ] on our own. However, to make an actual use of our time today, we will share 1 or 2 top additional questions we've heard over the last quarter to make sure they're included in today's transcript. So what I'd like to start with is a question of now that you've completed your SPAC transaction, what are the intended use of proceeds from here?

Great. Thanks, Matt, and thanks, everyone that asked that question over the last couple of months. It's nice to actually have the money in our bank account. So it's no longer what will we do, but we can actually get started on putting that money to work. There's 3 areas. The first is not surprising to drive more growth of neighbors to the platform and then once we get them to the platform, engaging them on the platform. We know that when we have neighbors on the platform, they're building community, they're finding utility, we know we will be able to monetize it down the line, so it behooves us to kind of start there first, given how young we still are in our overall global growth. And so in terms of overall investment areas, notifications, connections and, of course, improving the posting experience to make it easier and easier for neighbors to be active. And we will grow our team to do that. So that involves hiring engineers, data scientists, product people and designers. Area 2 is the ad platform. We have a massive opportunity here, right? The global ad market is large. It's growing quickly. People are moving from traditional formats to digital because they can measure it and see a strong ROI. Nextdoor sits on a very proprietary set of data, in particular, because we have placed and place allows us to do very unique things, particularly around targeting. We can target down to 0.1 of a mile. So it behooves us to keep investing in how we utilize that proprietary data, some more machine learning, more data science, that will give us the right ad, the right time, and the right person. And then the third area is our global opportunity. We believe everyone is a neighbor. We've already talked about seeing product market fit across our 11 countries. And in 2022, we want to begin to double down more on countries like France, Spain and Italy, that are high-opportunity countries for us, where we already have a presence. And over time, you'll see us invest to launch newer countries, too. Of course, our products will cause some of that viral growth to happen. Our partnerships with folks like public agencies will cause that to happen. But there's also some paid marketing that we do, particularly in the beginning of launching a new market, and that takes balance sheet power as well. So with that, maybe we'll take one more question.

Great. Thank you. So that segues into the final question we'll cover today. And that is what are Nextdoor's near, medium and long-term growth drivers?

Great. Okay. So to round it out, near term, we're just getting started. So of course, in the near term, it's about growth and engagement, notifications, connections. It's investing in the ad platform. I just talked through that, but also thinking about the small and midsized businesses. This is the place where Nextdoor is uniquely positioned to win in our opinion. We've seen our 54 million businesses get recommended on Nextdoor, for example. And we know that those small businesses, those local small businesses wants to be as digital as maybe the largest brands in the world, they just haven't had a great platform to do that beyond yet. But of course, we already see some of this happening and that's why our local, our smaller business revenue has been growing at a much faster clip from areas like professional services, home services, real estate, lots of people have been moving house and so realtors are quite active right now. For the medium term, we see a lot of opportunity to build active valued communities. So connections is something that I've spoken to that we're starting, but connections don't have a lot of legs in it as we go into 2022 and even beyond. So that is a big area of focus. We want to improve the ads deck. So we want to keep adding in both our own ways to measures, a pixel that Mike talked about, but also to keep adding into third parties. That means we're not just great in our own homework, but we can actually show that Nextdoor really outperforms. One place we do that is anyone who has an online to offline call to action. That's a place where Nextdoor tends to sing. And then an API strategy. So we know that we have done something incredibly hard, which is aggregate a lot of locals to 66 million verified neighbors but they all want to do many, many things. Over time, we'll build many, many of those things for them, but we won't be able to build it all immediately. And so this is where it behooves us to have an API platform where we can have partners, even advertisers step in and do something a little bit more ad-directed and increment with us. So you will see us start to invest in an API platform as we enter 2022. And then finally, over the long run, global. Everyone's a neighbor. We want to keep investing across all business sizes and across public agencies. We know the ad market is huge and we'll remain focused there. But over time, you could see us add other revenue models, for example, payments. Our marketplace is very vibrant. We see a lot of stuff put on for sale, also for free even on a monthly basis. And so this is certainly an area of opportunity, too. So I'll pause there. And with that, I think we'll bring the call to a close. Thank you.

That concludes the Nextdoor Q3 2021 Earnings Call. Thank you for your participation. And enjoy the rest of your day.
