Sean Green Turns Seed Rounds Into Series A Wins for Black Founders

Let me tell you about Sean Green.

His job is to make sure the check a Black founder gets at seed stage isn’t the last one they can raise — and he’s built a firm around making that true.

The Work

Green is co-founder and general partner of Black Operator Ventures (Black Ops VC), the Oakland-based seed-stage venture capital firm he launched with James Norman. His mandate is straightforward and hard: he leads the portfolio to maximize returns and owns deal flow — the sourcing engine that finds the founders the firm bets on. Black Ops VC closed a $20 million inaugural fund in 2021 and has invested in 15 tech startups, all aimed at closing the Series A gap for Black founders.

A defining deal: the firm led ChurchSpace’s $1.2 million oversubscribed round. ChurchSpace turns underutilized church real estate into economic engines for communities through event, logistics and last-mile delivery infrastructure — and Green has described it as a perfect reflection of the fund’s strategy: helping founders raise fully subscribed seed rounds with the governance and operational structure needed to hit the metrics for a successful Series A.

Green is also a three-time founder. He is founder and CEO of ARTERNAL, an AI-powered CRM and inventory-management platform built specifically for art galleries, dealers, auction houses and collectors. He and Norman have rebuilt their own companies into AI-native, agentic businesses — firsthand experience they now use to help founders make the same shift. The firm calls this “a new model of VC,” one that evolves at the speed of the companies it funds.

The Roots

Green’s road to venture ran through the operator’s seat, not the analyst’s desk. He’s a three-time founder, and it was a call from him to Norman that set Black Ops VC in motion — the pair stayed up for two straight days building their first deck. That intensity, and the conviction that a firm run by people who’d actually built companies could spot Black tech founders the market was missing, became the foundation of the fund.

His operating résumé centers on ARTERNAL, the art-world software company he founded and leads as CEO — a business he has scaled and rebuilt around AI. That experience is the credibility he brings to the founders Black Ops VC backs, and it’s why he and Norman describe the firm’s edge as “1+1=3”: every part of how they operate is intentional and strategic.

Why You Should Know Him

Because the Series A gap is where Black founders’ momentum dies — and Green is treating it as a returns problem, not a charity one. By leading oversubscribed seed rounds and then staying in the work, he’s helping companies build the exact profile the next round demands. That’s why Sean Green belongs on your radar.
