Peter Steinberger

Peter Steinberger created OpenClaw, which became the fastest-growing open-source project in GitHub history. After founding PSPDFKit (which he bootstrapped to a 100 million euro exit), he returned to coding and built OpenClaw as an open-source AI agent that attracted praise from Sam Altman himself. In February 2026, he announced he was joining OpenAI to work on bringing agents to a mainstream audience. His trajectory from bootstrapped founder to open-source AI legend to OpenAI makes him one of the most interesting builders in the space.
