Annie Lamont's Stamford VC Firm Backs $55M Healthcare Round

Stamford-based venture capital firm Oak HC/FT, co-founded and led by Annie Lamont, has backed a $55 million funding round for a healthcare startup, the Hartford Business Journal reports.

The round, disclosed by the publication without naming the recipient company, adds to a long line of healthcare investments steered by Lamont from the firm's Stamford headquarters. Lamont, who is also Connecticut's first lady, has built Oak HC/FT into one of the most active healthcare-focused growth investors in the country.

The $55 million commitment positions the round among the mid-sized healthcare financings of the current cycle. Such checks typically fund late-stage clinical scaling, digital health platform expansion, or the commercialization push that follows regulatory approval — although the Hartford Business Journal's report does not specify the startup's line of business.

What the report does establish is the geography and the lead. Oak HC/FT's involvement keeps significant deal-sourcing power anchored in Stamford, Connecticut, rather than in the traditional coastal venture hubs of Boston and New York. That detail matters for the state's efforts to retain and attract growth-stage capital.

The firm has a track record that makes its participation a signal in itself. Oak HC/FT was formed in 2014 from the healthcare and financial technology teams of Oak Investment Partners, and Lamont has spent more than three decades investing across healthcare services, information technology, and payment infrastructure. Companies backed by the firm have repeatedly gone on to raise follow-on capital at higher valuations or reach exit through acquisition.

For the unnamed startup, a $55 million infusion provides runway for the kind of expansion that healthcare ventures increasingly require: regulatory navigation across state lines, integration with provider networks, and the sales cycles that stretch longer than in most software categories.

The round also lands at a moment when healthcare fundraising has become more selective. Investors have tightened discipline since the peak years of 2021, concentrating capital in companies with proven unit economics rather than pure growth narratives. A nine-figure-adjacent raise backed by an established firm suggests the recipient cleared a high bar.

No valuation, structure, or co-investor details appeared in the initial report.

Expect the recipient's identity, use of proceeds, and any syndicate partners to surface in subsequent regulatory filings or company announcements — disclosures that will clarify whether this is a growth round for a scaled operator or a late-stage bet ahead of an exit.
