YBS Build-a-thon
Our flagship build weekend, run entirely online. Ideas on the board in the morning, working demos by the end.
Events Build nights, build-a-thons, demo days
Deadlines are the feature.
Everything we run ends the same way: you show the thing you made to a room full of people who will actually try it.
The YBS Build‑a‑thon
One weekend to take an idea from nothing to a working demo. Any stack, any category. Mentors on call all weekend, and live demos in front of judges who build for a living.
Fully online, so it does not matter where you are — if you have a laptop and a weekend, you can compete. First-timers very much included.
