Oak HC/FT

Co-founders Annie Lamont and Andrew Adams lead the firm as managing partners. General partners Matt Streisfeld and Nancy Brown head the fintech and healthcare verticals respectively, with each investment team partner covering a dedicated sector. The firm does not operate an executive committee above the general partnership; investment approvals run through the sector-focused general partners.

The firm positions its decade-plus network inside healthcare and financial services as its primary sourcing engine. Oak describes its thesis as building 'years of quiet conversations' before formal processes, and its portfolio company founders frequently cite the firm's ability to identify structural problems inside complex systems. The team also publishes compensation playbooks and AI founder resources as talent-marketing tools that attract early-stage companies.

Oak HC/FT operates as a traditional growth equity asset manager, not a family office. The firm raises and deploys third-party institutional capital through closed-end funds across venture and growth equity stages. There is no disclosed permanent capital base or single-family wealth origin.

Oak HC/FT invests solely through direct company stakes, from seed-stage checks to late-stage growth rounds. The firm does not operate a fund-of-funds program or take LP positions in other managers. Its strategy includes follow-on capital across a company's lifecycle, which functionally covers everything from a first institutional round through pre-IPO growth equity.

The firm is stage-agnostic within healthcare and fintech. It invests from seed and early-stage venture through expansion and late-stage growth, and it has a dedicated track record in complex situations such as corporate carve-outs and restructurings. Oak explicitly markets itself as useful across stages, citing the ability to lead rounds from day one through IPO.

Oak HC/FT states clearly that it invests only in healthcare and financial services. The firm does not pursue consumer internet, deep tech, defense, or industrial investments outside its dual-sector mandate. Even within those boundaries, its portfolio shows a preference for regulated infrastructure over speculative consumer apps.

The firm's portfolio shows a pattern of co-investing alongside other venture and growth equity firms in large rounds, evidenced by syndicated positions in companies like Devoted Health and Maven Clinic. Oak does not operate a formal club-deal program, but its partners frequently invest alongside other sector-specialist and crossover funds.
