Where Crypto Founders Start their Journey

Colosseum hackathons are not traditional hackathons. They are global, online competitions where talented founders sprint over multiple weeks to build impactful products. We run two hackathons per year, each followed by our accelerator program.

Can't wait for the next hackathon to launch your startup?

Join Eternal, a perpetual challenge where you can initiate a 4-week development sprint anytime and compete for $250K in pre-seed funding, accelerator admittance, and a chance to win the $25K Eternal Award.
