CEO Reviews

Brad Smith, Founder of Aspire Health, CareBridge and Main Street Health

Annie Lamont and the Oak HC/FT team are exactly the kind of investors every entrepreneur should want —they are the first people we bring every one of our deals to. I have now worked with Annie across three companies, and her strategic insight, experience and relationships are unmatched.

Kate Ryder, Founder of Maven

To affect change in healthcare, you must innovate from within, not try to blow it up from the outside. This is hard for some investors to appreciate, but the Oak HC/FT team has always gotten it. From the earliest meetings with Nancy Brown, I knew that she deeply understood the problems we set out to solve in women’s and family health, and what it would take to solve them. She has been a critical partner as we’ve navigated the complexities of our system and has genuinely contributed to our success.

Nuno Sebastião, Founder of Feedzai

Oak HC/FT is a full-stack investor. They have been with us from our early days through breaking out past our growth stage. What’s unique is that they’ve been useful at every stage because they know our space so well. They’ve shown up when we needed them. Not many investors can do that–they’ve always been there for me. Truly real partners the whole time.
