The first Founder Sprint: 48 hours, 100 hand-picked builders, one validation methodology.
Held July 11–12, 2026 · Bellevue, WA · Seattle eastside
The first Founder Sprint brought 100 hand-picked builders to Bellevue for 48 hours. Not to ship the most features in a weekend — to find the strongest evidence that their idea actually matters to real people.
Teams left with a working prototype, real signal from the market, and a business thesis they could actually defend. Here is how it went.

Signal over speed
Anyone can build an app in a weekend now — AI ships code in hours. The hard part was never the code; it was knowing whether anyone wanted what you built. So the Sprint rewarded evidence, not feature count: teams spent the weekend talking to real people, running real experiments, and following the signal.
A room full of people trying to do the same thing
Builders worked alongside operators, founders, and investors who had actually shipped. Mentors pressure-tested assumptions in real time, and the judging panel scored on the strength of the evidence and the clarity of the thesis — not the polish of the demo.
