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.
Over $700 million raised by hackathon winners in the past 4 years
80,000+ participants from across the world have competed in Solana hackathons, built thousands of products, and winning teams have raised funding from the best investors in crypto.
