Quoc Phong D.

Quoc Phong D. is a San Francisco-based investor associated with Century Oak Ventures, writing $100K to $250K at pre-seed through Series A into digital health and health IT software. The Century Oak affiliation suggests he is investing through a structured personal vehicle rather than purely as an individual angel, and the check size is large enough to participate meaningfully in small early rounds and occasionally lead pre-seeds. There is no LinkedIn listed, which is unusual and means founders should expect to find him via Crunchbase or warm introductions through Bay Area healthcare angel networks rather than direct social outreach. AI is not flagged as a focus, so the framing here is more on practical health IT and digital health software rather than model-first pitches. Founders most likely to fit are early-stage health IT and digital health companies with a working prototype, a clear buyer in providers or payers, and a path to early revenue. Biotech, devices, life sciences tools, and pure consumer wellness are weaker matches given the stated verticals. The Bay Area base is strongest for West Coast founders who can build in-person relationships, though at this check size geographic flexibility is reasonable. The entry path is via the Century Oak Ventures website contact form or a warm introduction from a mutual Bay Area healthcare investor, leading with the buyer persona, the wedge product, and the specific milestone the round funds. Cold outreach without a referral and without a LinkedIn channel is unlikely to convert.
