About

YC alum (S18). My last company, Shelf Engine, scaled to 10,000+ grocery locations, raised $70M+, and exited in 2024. Now building Super Labs - AI that understands really complex work. Also co-founder of Massive Tech Ventures, writing $500k checks to back YC founders. Happy to help with enterprise sales, fundraising, or anything to help the best founders.
