Jakub Rusiecki joins Colosseum as principal

Jakub Rusiecki, founder of Social Graph Ventures, said in a post on X that he has joined Colosseum as a principal. He said he first met Clay Robbins in January 2024, when Colosseum was getting off the ground and preparing to raise its first fund. Since then, Rusiecki said he had been tracking Robbins, Matty Tay and Nate Levine as the team worked to turn Solana hackathons into a company incubation pipeline. Over the past year, he said the two sides repeatedly backed the same early-stage projects and found themselves aligned on investment judgment at the earliest stages. Rusiecki also argued that much of crypto venture capital is now concentrated in later rounds, while many of the next wave of companies begin as two-person teams or hackathon projects, often before a typical fund would invest. He said Colosseum brings in developers through hackathons, supports founders from the idea stage through its accelerator, and uses its fund to keep backing breakout teams from the accelerator as well as other companies. In the new role, Rusiecki said he will review hackathon submissions and plans to attend Breakpoint in London.
