Ziad Rouag

Ziad Rouag is a San Francisco-based solo angel writing $25K to $100K at pre-seed and seed into medical devices and biotech. Public data is limited to a LinkedIn profile with no Crunchbase or website footprint, so founders should expect a personal-relationship angel rather than an institutional process. The Bay Area base is significant given that medical devices and biotech are not the densest verticals in San Francisco compared to biotech in Boston, suggesting his network may concentrate around Stanford-Bayview-Mission Bay translational and device circles rather than the digital health software cohort that dominates the city. AI is not flagged as a focus, so model-first pitches without a wet-lab or device anchor will be a mismatch. Check size and structure place him as a single-conviction angel, useful primarily as an early signal investor rather than a round leader. Founders most likely to fit are early-stage device teams with a clear regulatory pathway, biotech platforms with credible scientific founders, and any company that benefits from West Coast device or biotech network introductions. Digital health, consumer wellness, and SaaS for providers are weaker matches. Without a referral, the response rate will be low; with a warm introduction from a mutual Bay Area device or biotech connection, conversations tend to move quickly. The entry path is a LinkedIn message that leads with the science or technology, the team’s credentials, and the specific milestone the round funds rather than a generic deck.
