Felix Mercier

Felix Mercier is a San Francisco-based solo angel investor writing small early checks into pre-seed and seed companies, with a stated focus on digital health, AI in healthcare, and consumer wellness. He is currently Strategic Projects Lead at Mercor and is a recent backer of Charta Health, a healthcare AI company. The profile is a good fit for founders looking for a smart-money operator angel rather than an institutional check.

The thesis is built around founders applying AI to clinical workflow, administrative healthcare, and consumer health, with a preference for companies where his Mercor-derived perspective on labor markets and AI-augmented work is directly applicable. For digital health AI founders, that maps cleanly to ambient documentation, prior authorization automation, revenue cycle, scribe-style applications, and clinical decision support. Charta Health is the only specifically disclosed portfolio company in the source record, so founders should not assume a wide healthcare book; the value here is operator perspective and follow-on signaling, not portfolio aggregation.

Disclosed check size is under $250K, which positions Felix as a participation angel filling out a syndicate rather than anchoring a round. Stages are pre-seed and seed, with United States geographic focus. Founders should expect a fast yes or no decision typical of solo angels, with diligence weighted toward founder quality and the specific AI mechanism rather than detailed financial models.

This is a single individual, not a partnership, so the relationship is direct. The strongest channel is LinkedIn outreach with a specific, short pitch and a clear ask.

Approach Felix when you are a US pre-seed or seed founder building AI-enabled clinical or administrative healthcare software and you want a small, fast operator check from someone close to the AI labor-market thesis. He is not a substitute for an institutional lead and should not be approached as one. A warm intro through a Mercor colleague or a fellow founder he has previously backed will move significantly faster than a cold message. When reaching out, be specific about the clinical or administrative workflow you target, which AI primitive you use, and which physicians or health systems you have validation with, because that level of specificity is what differentiates a fundable note from a generic AI-in-healthcare pitch. Keep the ask scoped to a sub-$100K SAFE check.
