## About

PROOF.VC operates from Reston, Virginia, with an investment team that includes John Burke, Bryan Ciambella, and Prince Khaled Bin Alwaleed. The firm brands itself as an expansion-stage investor, stepping in when companies are scaling proven models. The strategy targets category leaders across enterprise software, fintech, digital health, deep tech, and consumer platforms. Confirmed positions include Zipline, the drone logistics company; Colossal Biosciences, which is pursuing de-extinction; sports network Overtime; mental-health platform Rula Health; daily-pay provider DailyPay; and 3D-printed construction firm ICON Build. The portfolio extends to cybersecurity, space — Astra delivers small-satellite launches — and alternative proteins via Beyond Meat. Geographically, exposure spans the United States, Africa, and the Middle East. Nine professionals are listed on the firm's team page. Leadership includes a Venture Partners group with Peter Harrison, Lisa Suennen, Ekta Tolani, and Zeid Masri. The firm also honors late co-founder John Backus. No recent fund close or headcount change is publicly confirmed. PROOF.VC's structural distinction is its co-investment model: the firm originates deals through relationships with seed-stage managers, providing growth capital while those managers retain ongoing participation. This architecture gives PROOF access to curated follow-on rounds and positions it as a liquidity partner rather than a competitive threat to early backers.
