excited to work with @pirroh and @amasad to bring the full power of AI to every knowledge worker and organization on earth.

Today, we're announcing that Sundial has been acquired by @Meta!  Chandra Narayanan and I are joining along with some other incredible members of our team.  Nearly six years ago, Chandra and I started Sundial with two core beliefs: 1) better decisions come from using data well, and 2) great things come from working on hard problems with people you like. Sundial automated away many of the obstacles involved in getting to meaningful analysis (Cleaning data! Creating semantic layers! Writing SQL! Storytelling!), and we were proud to support some of the fastest-growing AI companies from OpenAI to Gamma. We started before the AI wave and rebuilt ourselves to be AI-native. We raised our first round when interest rates were near zero, and our Series A when they were the highest in two decades. We watched customers hyperscale and then close shop, new grads grow into leaders, and software development change completely.  Entrepreneurship has been my dream since college, when I first took a class on start-ups (shoutout Mayfield Fellows!). I wish I'd been brave enough sooner because there’s no better way to learn how the world works and who you really are than betting on yourself to launch a business. Meta is my former home and where I learned product and design. It's also one of the most analytically rigorous places on the planet. So many of Sundial's values came from there: questioning assumptions, diagnosing with data, owning the user’s experience. I'm thrilled to bring what we've learned to the place where it all started and continue our mission of improving the quality and velocity of business decisions with people we like. To Team Sundial past and present, THANK YOU thank you thank you. You created that special feeling within our team, and I bask in the memories of having walked those lush miles and eaten those breakfast dosas with you. To our investors and supporters especially @dpatil, David Fischer + the whole 01A advisors team, @mvernal, @sequoia: how did we get so lucky to have your counsel and support? And to my beloved @mikesego and kiddos: I could not have made it without you.   These have been some of the hardest, most humbling, and most alive years of my life. I hope I'm wiser for it and will have many chances to pay it forward!  axios.com/2026/10/23/meta-ai…

Foursquare was acquired last month. The outcome was disappointing. It's taken me a while to write this, but I think I'm finally done grieving it. Here are some thoughts on our final years, an effort to honor the team who helped build & maintain FSQ's legacy, and my attempt to finally get some closure. teendrama.substack.com/p/som…
