Don’t just take it from us

Investors

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.

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

I've had the privilege of knowing Annie as an investor in my company and as a colleague at Oak. She consistently demonstrates an unwavering, steady hand in both the best and most challenging times, precisely what you want in an investor. I am always learning from her - not just as one of the industry's most accomplished investors, but also as a person of extraordinary depth.

Founder of TxVia, Clarity Payment Solutions, Money20/20, Shoptalk, HLTH

Annie is one of the most extraordinary people I’ve ever met, not just as an investor and a leader, but pan-dimensionally. I’ve known her for 25 years – as a business partner, a friend, and a human being. If a founder gets the chance to partner with and learn from her, that is a one in a billion opportunity.

Founder of athenahealth, Castlight, and Devoted Health, Chief Technology Officer of the United States

Oak’s talent team is one of the greatest value adds I've seen in a venture firm, ever. Working with them has changed the game for Brightline. They understand our business and sometimes even pre-empt my needs across talent and recruiting. They are true partners, confidantes, and champions.

Naomi Allen
Founder, Brightline

There is nothing more important than talent. Leah and the Oak talent team are incredible partners in scaling teams, because they have taste, experience, and incredibly deep networks.

Chad Cascarilla
Founder, Paxos

We develop essential therapeutics for patients who can’t wait. We launched on the brink of a global pandemic. Many hesitated or stalled, but Oak - and especially Andrew - leaned in. Their support enabled us to move swiftly, assemble a great management team, and engage with customers even when the world seemed at a standstill. This early momentum was invaluable – it meant bringing our much-needed services to the market without unnecessary delays. Andrew's ability to recognize the urgency and cut through distractions was a game-changer for us.

Many investors may claim to partner with founders, but Matt actually delivers on that promise. He has been with us since Day 0 – helping to validate our core idea and the strategy while making real contributions on execution, from recruiting to finance to partnerships. Matt does not hesitate to dig into details, and to roll up his sleeves to help solve problems together with our teams. He doesn’t just show up for board meetings once a quarter. He is truly bought into our vision, and it shows with each late-night phone call he takes or spontaneous strategy session in which he participates.

John Macilwaine
Founder, Highnote

Annie is an exceptional investor and treats every investment with a focus, commitment, and passion that is truly unique. Her credibility and depth of experience is best-in-class, and she has a rolodex and network built on decades of genuine and trusting relationships. I feel fortunate to have worked with Annie across three companies. I’m a better leader and executive because of her.

Puneet Singh
CEO, CareBridge

Leah and the talent team have been amazing. They connect us with relevant talent that raises the bar. They help me design org structure, comp, retention, and talent acquisition in a highly competitive environment. They connect us to the best recruiting resources for our most important leadership hires. In short - they are a huge competitive advantage.

To affect change in healthcare, you have to innovate from within, not try to blow it up from the outside. This is hard for some investors to appreciate, but the Oak 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.

Andrew has a keen eye for recognizing unique value opportunities in the market. His talent for working closely with founders and leadership teams is evident in his track record of building valuable, enduring businesses. What's particularly impressive is his thoughtful and concise approach, which consistently enhances our discussions and broadens our perspectives. In the world of investment, Andrew and his team are truly invaluable allies.

Doug Williams
Founder, Rialtic

Vig understands healthcare business models and what it takes to build and grow great companies. His pattern recognition from seeing hundreds of deals - including some of the leading companies in the space - makes him an awesome investor and thought partner. He can see around the corner to anticipate problems, and has the experience to know where and how he can support his portfolio companies. Even more important than his expertise is his commitment. He goes deep and works shoulder-to-shoulder with us to get things done - and that's what makes him unique. I consider him not just an investor and business partner, but a friend. We've built a foundation of trust that has served us for years across multiple companies and economic environments.

Puneet Singh
CEO, CareBridge

Andrew has amazing pattern recognition for discerning real vs. hype in rapidly growing companies. He pairs that ability with a commitment to discipline in pressure-testing your business model. He and the Oak team deliver an extraordinary blend of advice, introductions and market insights. They have built an amazing culture that is frictionless for entrepreneurs and spring-loaded to support growth companies.

Mark Clein
Founder, Precision Medicine Group

Nancy is unique amongst investors, because she is a former operator. On a daily basis years after investment, we continue to roll up our sleeves together, solve hard problems, and she is always pointing us to the big picture. Her even-keeled personality brings a calming point of view that helps our team continue to drive generational impact on the communities we serve.

Leah and the Oak talent team are exceptional. Their network is unparalleled, their dedication is relentless, and their knowledge of their portfolio companies is unmatched. More than just providing advice from the sidelines, they actively engage and operate alongside us. We are shaping our management team with their invaluable support. Talent expertise is a huge reason why Oak is a great partner for Prove.

Rodger Desai
Founder, Prove

Oak is a great fit for founders who understand complex systems and are serious about forcing impact. Because Oak knows these systems too, they're useful across stages. They do a lot of growth equity, but they've been an excellent early-stage partner for us from day one. The common theme is how much they know about the market (in our case – the customers, constraints, and valuable problems to solve in the fintech sector), and the depth of their networks in those ecosystems.

John Macilwaine
Founder, Highnote

Oak is not just a partner. They're an extension of our team. They seamlessly integrate, stepping in when needed and giving space when necessary. Their true value lies in their deep understanding of our business and extensive knowledge of the markets. With functional expertise across talent acquisition, go-to-market, product development, and finance, they're a formidable ally. If I ever start another company, Oak will undoubtedly be my first call.
