Thank you, Matt and hello everyone. Q4 rounded out a strong 2021 for Nextdoor. We grow significant neighbor growth at scale meaningfully increased engagement on the platform, welcomes businesses of all sizes with that delivers exceptional revenue growth. We also successfully completed our public offering, growing our cash balance over $700 million, putting us in a position of strength to continue investing for long-term growth. In Q4, we delivered strong revenue growth of 48% year-over-year and drove 32% year-over-year growth in weekly active users are well to 36 million. Total revenue growth for 2021 was 66% and accelerated by seven points year-over-year from 49% in 2020. Our strategy centered on building an active values community is working. While growth is driven by both new neighbors joining and finding value on Nextdoor, but also from current neighbors becoming increasingly more active. In Q4 well as a percent of total neighbors increased five percentage points year-over-year to 52%, which represents an all-time high. One of our key product initiatives in Q4 was the global launch of connections between neighbors. When you connect with another neighbor, you both have a more engaging personalized experience on the platform. Looking ahead, we plan to expand connections to all neighborhood stakeholders. We'll start by enabling neighbors to connect with small and medium sized businesses in the first half of 2022. And we'll follow with the ability to connect with large brands, public agencies, and other local organizations, and service providers. This will allow neighbors to hear from organizations they care about and it will enable organizations to create meaningful authentic connections with a uniquely engaged local audience. We believe connections will drive deeper engagement with Nextdoor because neighbors wants to hear from neighbors and organizations that they know and trust. We continue to drive innovation to…

Thank you, Sarah. And good afternoon, everyone. I'm pleased to report that we ended 2021 on a strong note. In Q4, we saw a second straight quarter of accelerating labor growth, with while reaching $36 million up 32% year-over-year, an increase from 20% year-over-year growth in Q3. Total revenue was $59 million, which was an increase to 48% year-over-year and 13% quarter-over-quarter. We saw healthy demand across advertiser sizes, objectives, geographies and verticals, our revenue continues to be fairly evenly split between direct response and brand marketing. And in Q4, we saw demand at all levels of the funnel. Throughout Q4, our advertisers came to us for creative impactful relevant campaigns that meets the moment. In addition to the Treat Map that Sarah mentioned, we had campaigns like our Holiday Cheer Map, Thanksgiving Cookbook and Veterans Day Campaign at Veterans United. Q4 global ARPU was 12% year-over-year to $1.65 driven by increased engagement among our neighbors. We also continued to build on our efforts from earlier in 2021 to better optimize our yield and improve our direct relationships with advertisers. While international is only a small part of our revenue today less than 5%, we are continuing to grow and prove out our model and advertiser value proposition in non-U.S. markets. In Q4, International advertiser count grew 74% year-over-year. Adjusted EBITDA for Q4 was a loss of $8 million. The six point year-on-year improvement in adjusted EBITDA margins, shows that we can remain in investment mode while also building towards long-term profitable growth. I'll end with our outlook. Our full-year revenue guidance is $254 million to $256 million. The year-over-year growth rate of 33% at the midpoint of the range, and an increase from our last full-year 2022 revenue guidance is $252 million. We expect full-year 2022 adjusted EBITDA margin to be minus 18% consistent with our prior guidance. For Q1 2022, we are expecting revenue of $48 million, the year-over-year growth rate of 40% and an adjusted EBITDA loss of $23 million. We are excited by the scale of our opportunity and our ability to execute against it. And we are going to continue to invest. Thank you for joining our earnings call today. With that, I'll turn it over to the operator for Q&A. Operator?

Thank you. [Operator Instructions] The first question is from the line of Eric Sheridan with Goldman Sachs. Your line is open.

Thank you so much for taking the questions. And I hope everyone on the team is doing well. Maybe coming back to the comments on advertiser momentum as you leave '21 and moving to '22. Can you quantify or giving us a sense of some of the momentum around advertiser diversity, advertiser budget, or how measurement in ROI continues to evolve as we move from one calendar year to the next, in terms of measuring some of the efficacy of some of the changes and that's which you've made, and how that means potential tailwinds to the advertising revenue in '22 and beyond? Thanks so much.

Eric, thank you for the question. It's Sarah, really appreciate it. I'm going to start just overall, talking about the ads platform right now, clearly a big area of investment for us. First and foremost, as we went through 2021, we began that shift over to our own proprietary ad platform. If you recall, Nextdoor has a fully logged in audience. We're not having to inference where you are, we're not following you around the web with cookies. And with that we have a lot of data that helps advertisers targets and clearly get outcomes of keeping them pretty excited whether it's for brand awareness or the whole way down into direct response. In terms of our investments here, as I talked about in my prepared remarks. First and foremost is the ad serving platform itself, what we call NAC. So that's the way in. And the big shift there to bring more advertiser diversity to the platform is of course opening up self-serve, because that will allow us to go from the smallest of micro merchant, we need to create an ad on the slide probably with a template as probably super busy, and not very sophisticated. All the way out to some of the most sophisticated advertisers in the world, including ad agencies who want to be really nimble with say, ad creatives and so on. On the backend, the main investment there is how do we serve the fast ads to the best neighbor at the best time for them. And something really differentiated. But Nextdoor, of course, is that ads on Nextdoor often content, because we're very high utility platform, people are coming in, and they're looking for the plumber, they're looking for maybe someone to help them do their betters in that moment. They're looking for a great financial advisors. And that makes Nextdoor really perform well across the whole kind of gamut of different advertisers. So in terms of the different cuts, you might think out, there's clearly scales, we can go from small to large that is where we plan the funnel. We can go from brand awareness to whole way to be art that is about evenly split. And then clearly there's diversity in terms of the type of advertiser, home services, home run for us, financial services, tech. We're starting to see some green shoots in areas like travel and entertainment as neighbors want to get out and about. And then PPG is an area that we've put a lot of investment into, and we're starting to see some really good outcomes. Hershey's is a great example. Mike, do you want to take how it really dovetails into guidance and digging up financials.

Sure. So the momentum with advertisers, that what's most important part is their interest in scaling up their campaigns and taking advantage of our larger engaged audience and the ability we have to offer more targeting and larger targeted groups. This ultimately help them to drive performance. We've also made significant investments in our measurement ecosystem, both capabilities on our proprietary ad platform as well as integrations with third-parties, which give advertisers more confidence to increase spend, being able to see results on the other side. So over the course of all of 2021, we saw increased retention and more evergreen spend, which helps us to have more visibility into our 2022 book of business, and allow us to build on a larger base.

Thanks so much.

Thank you Mr. Sheridan. The next question is from the line of Brian Nowak with Morgan Stanley. Your line is open.

Great. Thanks for taking the questions. I'll go back to the advertising question a little bit. Can you give us a little more quantification around what you're seeing from the ad platform or the self-serve maybe any nuggets of what the ad spending growth or the ad spending trends look like for advertisers before and after they adopt these new tools? This is only a little more idea of the momentum that you're talking about there, Mike, that'd be helpful. Then the second one, can you just talk to us a little bit about what the U.S. or the North America WAU trends look like? How quickly are those growing? And sort of what are the neighborhoods where you're seeing the most growth? And what's driving that? Thanks.

Sure. So let me start with the advertiser question. And what we're what we're seeing there. So first of all, the ad spending, demonstration of the results on the platform and the capability that we're able to deliver to advertisers both through our self-serve ad platform, as well as our improved measurements -- measurement capabilities, and in proprietary ad platform are demonstrated with most of -- in our revenue growth. And so we're seeing advertisers, an increased number of advertisers and a greater stand for advertiser. The demonstration of the value that they are seeing. Your question in particular about early indications from on our proprietary ad platform is we're very early in that migration. And we're working across all different segments of the advertisers from enterprise, mid-market and SMB to make sure that they're on boarded in a way that is constructive to the campaign that they're serving and ultimately opens up that increased spend. But we are -- we're early in that journey. So I think definitely we can comment on in future periods. Importantly, is the overall purpose of building a proprietary ad platform. And that's having a unified base of our inventory and getting access to the supply we have on the platform to all advertisers. So that can be best optimized across campaigns down to a single neighborhood or whether it's something much broader. That investments is relevant for all different segments of the advertisers. And it's one that reflects the lines we've had with advertisers over time to know exactly what they want from our platform. Second question was about WAUs trends. And so as we've talked about the $36 million WAU in the period with 32% year-on-year growth is something we're very proud of. Our product roadmap is focused on driving engagement. As we've talked about in the past, the reason we have that we focus on weekly active users is because we say there's a huge opportunity to bring mail on our platform and convert them into WAU and increase their session frequency, drive utility and improve the number of times they're coming back to the platform, as well as the content that they're creating and engaging with when they're on the platform.

Yeah, maybe I dive on the back of that WAU question. Thank you, Brian for it. So if you asked about North America U.S. in particular, overall, WAU work was 32% year-over-year up to $36 million. But if you look at U.S., WAU gross and distills the largest portion of our base accurate 30% year-over-year. So it's still a really healthy clip. When you're in one on three households. What you're seeing is there's not a particular neighborhood that I would point to this driving growth, it's really gross across the board. And one of the things that remains, I think are really strong part of the Nextdoor story is how many of our new neighbors come to us organically. That is saved in a really best-in-class sort of range and continues to be the case. In fact, when we looked at 2022, what you see is shifting a little bit more of our paid marketing spend into international, because we feel really good about what the product pipeline is doing to build growth and engagement in the U.S. In particular, in that product pipeline, there are a couple of areas that I would mentioned. Number one is connections, we went pretty deep on it in our shareholder letter, it's not really impacting results as yet. So on a backward look, we're not seeing a lot of impact, because it is only launched in Q4. But we definitely believe it will have a lot of impact growth and engagement as we look forward. Second thing I'd mentioned is that ad platform was great for advertisers. And it's great for driving monetization, both are great for neighbors, because the right ad at the right time is content. And that makes Nextdoor a very engaging, highly utilitarian platform for neighbors, the better and better we get at that. And then finally, we have put a lot of emphasis and investment into the evolution of the feed itself. We want to make sure that it's super easy to post so that you can be an active part of an active value community. We want to make sure it feels personalized, so you feel like you belong. And we think those are some of the things of reasons why even current neighbors are getting more engaged at the moment. One of the data points will probably like is that current neighbors, if you look in the last year have actually gotten more engaged. So we're seeing that kind of nice smile charts that we all love to see feel.

Great. Thank you both.

Thank you.

Thank you, Mr. Nowak. [Operator Instructions]. The next question is from Brian Fitzgerald with Wells Fargo. Your line is open.

Thanks, guys. In the letter, you noted some benefit from improved advertising flow rates. Just wondering if you could talk a little bit about what where you are in terms of the flow rates today and any sense for how budgets could expand as you continue to improve fulfillment. Maybe in the similar vein, the engagement metrics, while the neighbors really nice uptick movement there. Wondering if you could talk a little bit about the key factors there and where you think those can go over time as well. And then maybe one last one is just on, we've heard from some other companies over the -- of the quarter that the housing market is really tight. Wondering if you're seeing any dynamic in terms of relation to a tight housing market to uptick or look for certain services related to new houses or not being in new houses, those types of things?

Yes, okay, maybe I'll start on the engagements on the housing market movers. And then I'll pass back to Mike on advertiser fill rates and so on. So on overall engagement, first and foremost, yes, we're superbly it's about 32% year-over-year growth on WAU. And the fact that the second quarter have engaged in growth. We do continue to regrow traverse. One is top of the funnel, so you verified neighbors grew about 20% year-over-year in the same period. So it's good, we have new neighbors coming all the time. But then importantly, those neighbors are becoming more and more active. So it's a two-third, new neighbors, and then current neighbors becoming more active. The other way that you can see that is the depth of engagement, the fact that WAU as a percent of total neighbors, is that 52% globally, that grew five points year-over-year. And so that underscores that point that new neighbors are to come on more and more active overall. I'd also take you back to the chart that we showed in our Investor Day. If you recall, after three months, 75% of our mails are coming back, after six months 65% and after two years, you still see more than half of new neighbors to make sure actively engage. This is world class. And I would remind everyone that even a weekly active is coming back on average 4x per week. So the great news is once we get you from verified neighbors now to WAU, your propensity to step over to be a DAU is very, very high. On the DAU funds, what we're seeing there is beginning in 2020, and are simply beginning of 2020 for three months or six months or 12 months and the 24 months, DAU cohorts have all seen…

Hi, Brian. So first, I wanted just to talk about, really the three types of letters we have to drive monetization. And really, for us it is and there's efforts behind each. So the first and most important is as driving deeper engagement. So it's creating incrementally more supply. So we can attract more advertisers, greater budgets, and have larger targeted audiences for those advertisers. The second is in supply optimization. So this is where fill rates come into play. That's where the next step direct sold comes into play. It's making sure that we are serving the right ad at the right time to improve yields for advertisers, which ultimately which benefit us in our CPMs and benefit performance for the advertisers themselves. And then the third bucket that we think about is a wave straight monetization outside of the direct creation of supply. And so for its monetizing differentiated surfaces that we have things like maps, and groups, our classified surface where there's opportunity to drive value for the ecosystem, it doesn't necessarily requires incremental expansion of supply. Let me come back to the second bucket, which is your question on fill rates. And this is one where we had tremendous success in 2021. And that is driving fill rates higher. Q4 is seasonally our best quarter. So there's a tremendous amount of demand for our inventory. But what we saw was increasing flow rates year-over-year in all of the quarters in 2021. And importantly, with the verticalization of our Salesforce, getting closer to the advertisers and knowing deeply the industries that they covered it is allowing us to increase the mix of direct sales campaigns and not having to rely on backfill partners to fulfill unsold supply. We do have partnerships, nonetheless, but it is a key metric for us to drive that percentage higher when we're proving real value to the advertisers directly and also where there is higher yields. So that's something we'll continue all focus on all three of those categories of leverage in 2022. But with continuing to refine the prioritization of each and I'd say the biggest opportunity for us in 2022 is on the first bucket which is driving higher engagement.

Thanks guys.

Thanks.

Thank you, Mr. Fitzgerald. There are no additional questions waiting at this time. I will now turn the call back to Matt Anderson. Excuse me, there is an additional question from Mark Mahaney with Evercore. Your line is open.

Okay, thanks. Let's see, I wanted to ask about relative engagement levels of international versus the U.S. Do those trends look relatively similar the cohort trends, you've seen international markets kind of follow the pattern that you saw in the U.S. and then I have a follow-on please.

Great, thanks, Mark. We were wondering where you were, we wanted question. So I think actually positively right now, we see even better engagement outside the U.S., even though we think our engagement in the U.S. is already quite best in class. And so if you look at the four markets that we really went after, in 2021, so Canada, Australia, Netherlands and U.K., we saw almost 50%, year-over-year growth. But the way members engaged for 58% of neighbors are coming back week like, and as I said, like our average weekly users coming back up to four times a week. And I think, actually, in the U.K. it is even a little bit more than that. Another data point I'd give you in the U.K., we're now up to one in five households. And in London, that is one in four. And that's important because London is such a big advertiser market, that we need to have density there. So we can do the sort of targeting that a particular advertiser needs. So we're really actually upbeat and excited about what we see going on outside the U.S. as a growth lever for kind of multiple years to come. In 2022, we're going to focus a little bit more deeply into Western Europe. So France, Italy, Spain, and Sweden, those are all very large ad markets. So we know if we can get the neighbors on board, there's definitely a high monetization ability. And those markets have been the same for us in many ways, we see the same sort of neighborliness, the good news is, everyone is a neighbor. And we know that Nextdoor can be a global platform. As you know, International revenue today still only about 5% or less of total. So it is I would say more of a future growth lever in 2022, and even much more into 2023 and beyond. But we are going to tip our investments more strongly outside the U.S. in 2022 really because we're so confident in the growth that we're seeing in the U.S., organic growth still very, very strong. And we know there's a network effect. So now when we're in one and three helpful, there's just kind of a natural, sustained growth rate that doesn't need kind of paid marketing and so on, to keep it bolstered.

Okay, thanks, Sarah. And then I want to ask you about Connections. And so you launched this, and I know you talked about it in their shareholder letter, you launched this, do you talk about what impact that's had on engagement in the communities? Are we aware it's been launched so far? And then what's the use case, basic use case for enabling neighbors to connect with small and midsize businesses like how widely adopted you think that'll be?

Yes, so Connections rolled out in Q4 globally, but really towards the end of the quarter. So you're not seeing really any impact on it in the results that we just put in front of you, which I think is the good news, actually. Because we do expect it to start having an impact on engagement as we get into the back half here. Why is that? Well, one thing we know is that people you know, our neighbors you know, talking about things you care about clearly very high on the engagement front. But the next time his neighbors talking even about things who maybe don't care as much about, the human values, more than they do just pure in trust. So we're leaning into that insight. And know that as neighbors connects other neighbors, they're going to get a more personalized feed. And we think that's just us overall engagement feeds into our notification platform, our notification platform is getting more intelligent. So it should have a really good flywheel. Where you're growing we want of course, connections to not just the neighbor to neighbor, we want us to be neighbor to business, small business, midsize business, large brands, ultimately public agency and in any other neighborhood organization. On the business front, what gets very interesting for the business is you now have someone actually putting their hand up to say, I care about this business, I trust this business, I want to make sure I'm hearing from them. So it almost opens up a direct line of communication. Not too much one to one, a bit more one to many. But one of the things we absolutely know on our platform is many of our neighbors are also business owners. So there because of course they want they're in business, they want to make revenue, but they're also there because they care about their community. And I think what they find when I talk to them more anecdotally is the more they create a sense of community around their business, the more effective they become as advertisers. If I think about consecutive small business is actually a farmer and his business is selling meat, he sold beef, lamb and so on. But he spends probably the majority of his time talking more about what's going on in the farm right, it's sprung, it's lambing season here's the -- we're now saying whatever we're about to feed our cows and it's about one in every five posts that he actually makes much more commercial and that's been way more effective for him and his business than just.

Sarah, are you still there? [Technical Difficulty].

One moment we will reconnect the speaker. [Operator Instructions] It looks like no one else is going to join this call. Good bye. [Operator Instructions]
