During his studies in
Vienna University of Technology, he established himself as an early adopter of Apple's
iOS platform. In 2010, Steinberger founded PSPDFKit, which provides document processing and
PDF frameworks for mobile and web applications. Others who helped create PSPDFkit as a company include Jonathan Rhyne and Martin Schürrer. In November 2025, he released an open-source project initially named Clawdbot (later renamed Moltbot, and finally OpenClaw). OpenClaw is an autonomous AI agent that interacts with users through messaging platforms such as
WhatsApp,
Telegram, and
Discord. In February 2026, he announced he would be joining
OpenAI and rejecting an offer to join
Meta. Steinberger is scheduled to give a talk at
TEDAI Vienna in 2026. == Personal life ==
