Oak HC/FT

Co-founded by Annie Lamont and Andrew Adams, Oak HC/FT emerged from a predecessor healthcare and technology investment practice and now runs a concentrated growth equity strategy across two verticals: healthcare and financial services. The firm makes early-stage, expansion, and late-stage investments, sometimes entering at seed and continuing to invest through IPO — a full-stack approach that few sector specialists sustain. Lamont and Adams have built the team around practice-area general partners, with Nancy Brown leading healthcare and Matt Streisfeld leading fintech, supported by a partnership group that includes Allen Miller, Andy Smith, Billy Deitch, Marc Andrusko, and Vig Chandramouli (per firm website, accessed 2026). The portfolio spans digital health infrastructure, value-based care delivery, fintech infrastructure, and enterprise financial software. Confirmed positions include blended lenders (Blend, IPO: BLND), stablecoin-enabled money movement (Bridge, acquired by Stripe), Medicare Advantage payvider and primary care platforms, ambient AI documentation, revenue cycle automation, and AI-native ERP. Healthcare investments cluster around provider enablement, home-based care, and risk-bearing clinical models. Fintech positions concentrate on LatAm treasury and ecommerce logistics, private markets infrastructure, identity verification, and automation platforms serving banks and insurers. The firm co-invests alongside GPs and participates in structured growth rounds, club deals, and direct company stakes across the United States, Latin America, and Europe. Team depth is unusual for a sector fund: the website lists over 50 professionals including dedicated talent partners, a portfolio management group, an investor relations partner, and venture partners with prior operating backgrounds at healthcare and fintech companies. The firm publishes a compensation playbook for portfolio companies and maintains an advisor roster that includes former pharma executives, payments operators, and data infrastructure founders. While Oak HC/FT does not disclose total AUM or deployment figures, its public portfolio count exceeds 80 active companies (per firm website portfolio listing, May 2026). In recent activity, the firm's portfolio company Bridge, a stablecoin-based cross-border settlement platform co-founded by Zach Abrams, was acquired by Stripe — one of the largest fintech exits in Oak HC/FT's history. Structurally, Oak HC/FT diverges from generalist multi-stage funds by refusing to diversify away from its two target sectors. This concentration forces the partnership to develop regulatory and operational fluency that generalist firms cannot replicate — every general partner, principal, and venture partner operates solely within healthcare or fintech. The firm has not diversified into climate, defense, or consumer internet. The result is a deliberately narrow mandate that functions as a permanent thematic constraint, even as the underlying companies span seed to pre-IPO stages.

Frequently asked questions

Who runs investment decisions at Oak HC/FT?

Annie Lamont and Andrew Adams are Co-Founders and Managing Partners. Day-to-day healthcare investment decisions sit with General Partner Nancy Brown, while Matt Streisfeld leads fintech investing. The partnership group includes dedicated partners across both verticals; no single person controls all capital allocation.

How does Oak HC/FT source proprietary deal flow?

The firm relies on a decades-old network inside two insulated industries — healthcare and financial services — where regulation creates persistent barriers to entry for generalist investors. Its team includes venture partners and advisors who previously held operating roles at healthcare payers, pharma companies, and payments platforms. The firm emphasizes quiet relationship-building over deal auctions.

Is Oak HC/FT structured as a single family office or does it operate more like a venture firm?

Oak HC/FT is a private equity firm, not a single family office. It raises institutional funds and deploys them as a growth equity investor, spanning early-stage venture to late-stage control positions inside healthcare and fintech. The firm does not manage a single family's capital.

Does Oak HC/FT participate in fund commitments or only direct deals?

The firm primarily makes direct company investments. Its portfolio shows direct stakes in operating companies across stages, with no disclosed fund-of-funds or LP commitments to external managers. It does co-invest alongside other venture and growth firms in structured rounds.

What investment stages does Oak HC/FT typically target?

Oak HC/FT invests from seed through late-stage growth, and has held positions through IPO. The firm's portfolio includes early-stage AI companies, expansion-stage provider enablement platforms, and later-stage companies like Blend, which it backed before its public listing (IPO: BLND). Stage flexibility within healthcare and fintech is core to its mandate.

Which sectors does Oak HC/FT explicitly avoid?

The firm does not invest outside healthcare and financial services. It has not entered climate technology, defense, consumer internet, or traditional enterprise SaaS unrelated to its two verticals. Even within fintech, it largely avoids pure crypto speculation, focusing instead on infrastructure, payments, identity, and regulated financial products.

Does Oak HC/FT maintain philanthropic structures, and how are they separated?

No separate philanthropic foundation is publicly disclosed as controlled by the firm. Individual partners may have personal philanthropic activities, but Oak HC/FT itself operates solely as an institutional private equity manager. There is no public record of a formal impact vehicle or foundation affiliated with the firm.
