MEGATHON
MEGATHON is here. Time to make Europe great again.
We're putting together a stage Europe never built — and we're inviting the best builders into the arena. The arena is a free market: 500 vetted builders, one weekend, and the VCs and investors in the room deciding who gets the attention. Build the best startup of the weekend, or take on one of the tracks from our sponsors.
June 19–21, Amsterdam. Part of Amsterdam Tech Week.
What you need to know:
The format. Doors open Friday 16:00. The clock starts Friday 18:00 and stops Sunday 15:00. Main-Stage Finals Sunday 18:00 — livestreamed globally, prizes awarded live. Bring Your Own Startup: your real project, not a weekend toy. We judge momentum, not polish.
The prizes. €100K+ total pool: ~€20–25K in cash, €25K+ in credits and tokens, trips, a content campaign built around the winners, and software from all the amazing suppliers backing this event. Compete for the main prize or win a sponsor track.
Getting in. Applying is free, spots are vetted. Apply with a team or solo — Friday evening is built for solo builders to find their people. Food and drinks all weekend, rest zones in the venue, and everything you build stays 100% yours.
The names behind it: Presented with Codex by OpenAI, Mollie, Visa, Base44, Cognition, Peak and TAG. Powered by Miro, Wispr Flow, Vapi, Nebius, PixVerse, Cala, Netlify, Lemlist, Neno, AI AM, EventsPoint, Tectonic, Livestream Lab and Provoke. Community partners: EuroTech Federation, Tulip Ventures, BabyVC, Young Creators, AI Beavers, AI Builders and Amsterdam Tech Week.
If you want to unite Europe. If you want to start a startup, or launch one this weekend. If you want talent, polish, and hard work around you — this is your weekend.
