MEGATHON 2026 — Europe's Biggest Builder Hackathon

MEGATHON descends on Amsterdam for 45+ hours of building, shipping and pitching - billed as Europe's biggest builder event. Roughly 500 vetted founders, engineers, designers and makers gather at The HUBB to launch around 150 startups live, competing for a prize pool north of EUR 100,000. Mentors, operators and investors from Mollie, Codex, Miro, Peak Capital, Visa, Wispr Flow, Tulip Ventures and BabyVC will be in the room, on hand throughout the weekend. Bring a project or join a team on the ground; food, drinks and quiet rest zones run across the whole event. If you want to build something real and meet the people who can help you scale it, this is the room to be in.
