Peter Steinberger, a millennial developer who revolutionized PDF formatting with PSPDFKit, has resurfaced in the AI world with OpenClaw, an autonomous AI agent that functions as a digital employee. After a €100 million exit in 2023, Steinberger vanished from tech circles, citing burnout, before returning in 2025 to build OpenClaw—a tool that manages emails, automates workflows, and even checks on user well-being. The project, which peaked at 145,000 GitHub stars, drew praise from Sam Altman and Mark Zuckerberg but faced challenges like account hijacking and ethical debates over open-source autonomy.
