OS After Party 2026 × MAIN SPONSOR

​Heads up, the address for this one is still being sorted out, so stay tuned for updates on the location.

​What started three years ago as a scrappy little afterparty for OpenSauce has turned into something genuinely wild. Thirty people showed up the first year. Then 280. Last year we had to turn people away because we ran out of room. So this year we are figuring out a bigger and better setup worthy of the crowd that keeps showing up. If you have been to one of these before, you already know the vibe. If you have not, imagine a few hundred people who just spent a day geeking out over science, making, and building things, all unwinding together at the end of the night. It is loud, it is fun, and there is a good chance you will end up in a conversation you did not expect. More details on the venue and any sponsors coming soon, but get your spot locked in early because last year we genuinely had to cut the list.
