FROM: Sarah Friar, Nextdoor CEO (no-reply email address)

Hi {FIRST NAME},

Thank you so much for supporting your Nextdoor neighborhood as a {ROLE NAME}. When we started Nextdoor it was apparent that despite technology’s ability to connect people and communities across the globe, in actuality people had become more disconnected. This inspired us to think: what if we could leverage technology to enable real-world connections? What if Nextdoor could become a place where neighbors can naturally come together to help make their local communities better?

With your support Nextdoor has grown into the place that millions of neighbors across 11 countries visit in order to connect to the 275,000+ neighborhoods that matter to them. You’ve helped answer your neighbors’ questions, invited and welcomed new folks to your areas, kept conversations respectful, shared your neighborhood’s history, and more. And as a result, neighbors across Nextdoor have found a place where they can connect and belong.

Today, we’re thrilled to announce our next step towards becoming a public company. This process will further enable our purpose to build a kinder world where everyone has a neighborhood they can rely on, and it will accelerate our plans to support you in building stronger, more vibrant, and resilient neighborhoods. As part of this effort, we also announced the launch of the Nextdoor Kind Foundation, which will be dedicated to making local grants to help neighbors strengthen their neighborhoods around the world. Details are available in our press release.

Nextdoor has come a long way over the past 10+ years, and the passion and purpose that you all contribute to your neighborhoods has been the common denominator. We are so grateful to be on this journey together, and look forward to continuing to build connection and belonging in the neighborhood for years to come. Thank you again for your support of Nextdoor.
