Thank you, John T. Good afternoon, everyone. I'm happy to be with you today to discuss our fourth quarter 2024 financial results and outlook. When we created Nextdoor, we did so with the belief that connected neighborhoods create stronger communities. Today, 14 years later, more than 100 million verified neighbors have joined our platform to improve their local lives. We've definitely made a real impact. At the same time, we haven't come close to fulfilling our potential, both as a business and more importantly, with our product. So about a year ago, I came back as CEO to drive complete transformation of our user experience we call it NEXT, a reimagined and significantly improved version of Nextdoor. Since my return, our team has worked hard to create a robust foundation for future growth. And while there is much more work to do, I'm encouraged by our progress and excited to share some specific details about the emergence of NEXT on today's call. But before setting the stage for what's next, no pun intended, let's talk about our Q4 and full year 2024 results. Q4 marked a strong finish to the year. Weekly active users increased 10% year-over-year, reaching $45.9 million. Revenue grew 17% year-over-year to $65 million. For the first time, we achieved positive adjusted EBITDA and operating cash flow, an important milestone. Throughout Q4 and really all of 2024, and we showed that a disciplined balance between strategic investment and cost controls can drive sustained productivity gains. All of these results were made possible by an unwavering focus on execution and reinforce my most important belief about winning organizations. People are the core asset. Establishing the team was a key focus in 2024, and I'm confident that we now have the right talent in place across the organization to drive Nextdoor forward. This includes our additions of Georg Petschnigg from the New York Times as Chief Design Officer and our promotion of Michael Kiernan, to Chief Revenue Officer. Our entire company has embraced the challenge of transforming Nextdoor and last year's financial and operational results are clear evidence that we're making progress. But the most important piece of the transformation is next and our top priority is very clear, delivering a new and radically improved user experience. To do this right, we are moving away from incremental optimizations of our existing product and fully committing our focus and energy to iterating, refining and ultimately launching NEXT. While we expect the switchover will impact short-term results, it is a necessary step to secure our long-term success. So let's talk in a little bit more detail about next. Our vision is to unlock the full promise of the neighborhood, and we've spoken to our users a lot over the last year to understand exactly how we can do that for them. They've told us that they want to use next door, but they needed to work better for them. Simply put, they want the local information to be more relevant, the interface to be more intuitive and the notifications to be more high value. Next is purpose-built to meet these needs, and it focuses on 3 key areas: richer local content, timely local alerts and community-powered local recommendations. These are the 3 pillars that comprise the foundation for our high conviction strategy for NEXT and deliver on the core needs of keeping users informed, safe and smart. I would like to explain each of these in a little bit more detail. First, we are adding new sources of local content to help keep users informed. Richer local content means providing all of the news and information related to what is happening locally. In the past, user-generated content has been our primary source of local updates. NEXT will now integrate third-party non-neighbor publisher content alongside these neighbor discussions, creating a richer and more reliable local news experience that delivers daily and predictable value. Second, we are upgrading live local updates to help keep users safe. Weather, power, traffic, these are alerts that are essential for our users. In the past, these critical pieces of information might be hard to find or quickly become outdated. NEXT, will deliver alerts in a more prominent design that prioritizes real-time delivery and accuracy, serving as an essential lifeline for neighbors during crises such as the recent L.A. fires or for everyday needs like your daily commute. Third and finally, we are surfacing community-powered local recommendations to help keep users smart. Neighbor recommendations are at the heart of Nextdoor and have always made up a significant portion of our posts. In the past, this knowledge looked only in the feed making it difficult to find. Next, we'll use AI and ML to centralize recommendations in a new neighborhood hub where we can showcase the most valuable evergreen content contributed by users over many years. In the last 6 months, we have prototyped and tested parts of NEXT in 6 markets around the country. We've seen some useful early signals and initial feedback gives us confidence in our strategy. Given these learnings, our product development teams have materially shifted their efforts during Q1 to prioritize next related development work officially initiating the switch over to NEXT. And I've said many times the product transformation is not a straight line, and we have always anticipated the uncertainty in shifting from vision to execution. But we're now ready to embrace this uncertainty because NEXT allows us to directly address our users' core needs. Delivering a materially better product is the only way to build the successful business that we all envision for next door. With that in mind, we are intentionally making short-term trade-offs to prioritize long-term value. This may include things like focusing on existing users over acquiring new ones reducing ad load to deepen engagement or other strategic shifts that certainly will influence usage patterns. As a result, we do expect impacts on weekly active users and impressions, which will affect near-term business results. This is not a decision we take lightly, but we believe it is the right one. Embracing this switchover period of feedback and transition is essential to delivering a transformed product and ensuring Nextdoor's long-term success. With all that said, I'm pleased to share that we remain on track to launch NEXT as promised by mid-2025. We validated the product vision, built much of the technology and are now beginning to switch over process. While we expect some ups and downs in the coming quarters, this work is laying the foundation for our long-term success. Nextdoor has tremendous potential, and we look forward to keeping you updated on the rollout of NEXT in the months ahead. I'll now turn it over to Matt to discuss our financial results.
