Hey, I’m Bartek
I’ve been reading, listening, thinking, writing, building, and investing on the Internet since 1997. Currently building Proofs - AI Agents for sales engineering.
I also invest in early-stage founders building companies at the frontiers of progress. My areas of interest are AI, tools, infrastructure, defense and space.
Invested in over 15 companies, including:
Often investing with my angel syndicate. Previous co-investors include a16z, Sequoia, OpenAI Fund, YC, Felicis, and others.
