Introducing Colosseum Accelerator Cohort 3

We are excited to unveil Colosseum's third accelerator cohort. The batch is composed of winning founders from the recent Solana Breakout Hackathon and our ongoing Eternal challenge. 1,412 teams submitted products in the hackathon, along with an addition 61 submissions from Eternal in H1 2025.

From the pool of winners, Colosseum selected 10 total startups to invest in and accept into the accelerator program, which means the program acceptance rate was roughly 0.68%. We believe each of these startups has exhibited the technical talent, speed, vision, and competitive drive required to build successful, enduring products that will significantly grow the Solana ecosystem and broader onchain economy.

In no particular order, the following startups will be joining Colosseum Cohort 3:
