Brennan Erbz is Co-Founder of Tab, a San Francisco-based consumer AI agent that operates natively inside iMessage and WhatsApp, allowing users to delegate real-world tasks through text.
Brennan worked as a machine learning engineer and Product Designer at Snap Inc. before its IPO, then earned his B.S. from Villanova University and went through Y Combinator's Winter 2020 batch.
He previously built and sold Hashletes, an NFL-licensed digital trading card platform backed by Khosla Ventures, demonstrating his track record of building and exiting consumer tech ventures.
Brennan co-founded Flik, a generative AI platform for film, ad, and music production, unveiled in April 2026, before launching Tab later that year alongside co-founders Stafford Schlitt and Ammar Amdani.
Tab emerged from stealth on October 7, 2026 at a $300 million pre-seed valuation, backed by SV Angel, Valar Ventures, and American Spirit, positioning it among the most richly valued stealth-stage AI startups of 2026.
