Where Crypto Founders Start their Journey

Colosseum hackathons are not traditional hackathons. They are global, online competitions where talented developers and founding teams sprint over multiple weeks to start building impactful products with scalable business models.

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.
