Background
Samuel
Barnes.
I’m Samuel Barnes: a growth leader, founder, and hands-on builder. An MPA in Environmental Science and Policy from Columbia University shaped my work across climate, energy, Web3, and AI.
I work across the commercial and technical sides of a product: who it serves, how it works, and how it reaches people. Away from work, I make music, organize gatherings, and spend time with my family. I’m based between Brooklyn and Vancouver.
