Friday Kick-off
Find your people. Form your team. Scope it. By Saturday morning, you're shipping fast.
Saturday Night
Food, music, and 500 people who get what you're doing. Or keep building. Your call.
Main-Stage Finals
Demo day on steroids. Top teams pitch live to a packed room. Judges decide. €100K+ awarded on stage.

Questions
Before you apply.
Yes — applying is free. Spots are limited and vetted; we select 500 builders out of every applicant pool.
Bring Your Own Startup. You arrive with your real project, not a weekend toy. The point is momentum on what you're already building — not a themed sprint where everyone ends up with the same demo.
Mostly self-formed. Friday evening is structured to help you find your people if you arrive solo. By Saturday morning your team is shipping.
Two axes: momentum — where you started Friday vs. where you ended Sunday — and how clever the idea is technically and business-wise. Polish isn't the metric.
Yes. You retain full ownership of everything you build at MEGATHON. No silent IP transfers, no obligations.
Venue is in Amsterdam. Food and drinks are provided throughout the weekend. Sleep is your call — quiet rest zones are available. Saturday evening is a community moment you can opt into or keep building through.
Yes — the Main-Stage Finals on Sunday are livestreamed globally. The €100K+ prize pool is awarded live.
No. MEGATHON is open to everyone who wants to build — founders, engineers, designers, students, makers. Bring a project you're working on, or join a team on the ground. The only filter is that you actually want to ship something over the weekend.
