PROOF.VC

PROOF.VC sources expansion-stage investments primarily by co-investing with early-stage venture capital managers who already hold board seats and relationships with the founders. The firm's partners, including Thanasis Delistathis, describe showing up with a 'prepared mind' on every opportunity, and the model enables the original early-stage backers to retain participation while PROOF.VC supplies later-stage capital. Frontier Venture Capital's founder has publicly stated that PROOF.VC's approach creates a structural 'win-win' for both sides.

PROOF.VC makes direct equity investments into expansion-stage operating companies rather than committing capital to external venture funds as a limited partner. Its website and team statements indicate a model built around direct co-investment alongside other venture capital firms. There is no public evidence of a fund-of-funds or LP allocation program.

PROOF.VC self-identifies as an 'expansion-stage firm investing in companies that are ready for their next phase of growth.' Its portfolio includes companies that have already cleared early venture rounds and are scaling commercially, spanning sectors from digital health (Rula Health) to industrial robotics (Desktop Metal) to consumer (Overtime). The firm does not market itself as a seed or pre-seed investor.

The investment team is led by co-founders Thanasis Delistathis and John Burke, supported by Bryan Ciambella, Jennifer Schretter, Prince Khaled bin Alwaleed, and Ha Dao. The firm's website does not designate formal titles such as Chief Investment Officer or Managing Partner, instead listing the six as the collective 'Investment Team.' Venture partners including Peter Harrison and Lisa Suennen also contribute to the firm's deal evaluation process.

PROOF.VC is structured as an asset manager and operates as a direct private equity and venture capital firm, not a family office. The presence of Prince Khaled bin Alwaleed on the investment team suggests some relationship to notable private wealth, but no public materials characterize PROOF.VC as a single-family or multi-family office. Its external posture with co-investors and portfolio companies is that of a sector-agnostic expansion-stage fund manager.

PROOF.VC does not publish a list of excluded sectors. Its publicly disclosed portfolio spans enterprise software, fintech, digital health, space technology, climate tech, and consumer media, among others. No negative screening criteria or forbidden verticals appear in available materials.

The firm's website identifies 13 named professionals: six on the investment team, three on the operations team (Maggie Varona, Michael Zarlenga, Melanie Ness), and four venture partners (Peter Harrison, Lisa Suennen, Ekta Tolani, Zeid Masri). PROOF.VC does not disclose total headcount or the number of administrative staff beyond the operations unit.
