our focus

Innovation in life-science and resource-driven sectors

3x5 invests in and builds companies pioneering innovative solutions in the life science and natural resource sectors. We identify companies that reduce and evolve the consumption of the planet’s limited resources, including energy, food, waste, water, and other natural resources. We seek opportunities in the life-science sector to improve patient outcomes by developing innovations in biopharma and medical devices. We believe that these solution leaders will become some of the most valuable companies of the future.

We are all passionate about the technologies we are developing and the companies we’re building.
— Steve Girouard, Portfolio Company CEO

Committed to Solutions


our strategy

Our portfolio companies are creative, passionate and committed to solutions

We build healthy companies through employing patient capital, and through a strong, independent Board of Directors to support and empower a talented CEO and management team.

I don’t believe that there is another investment firm that would have so patiently endured the challenges that we found along the road.
— Gregg Rotenberg, CEO Smart Wires

Relationships are at the Heart of our Returns


our Philosophy

Relationships grounded in trust, commitment, and shared vision

We are long term relationship-driven investors, working serially with entrepreneurs, CEOs, and investors. We carefully select our partners and build relationships grounded in trust, shared vision, transparency, and mutual accountability.

Great investment partners are more than just money, and of course, when it’s more than just money, it’s about people.
— Cody Friesen, CEO Zero Mass Water

Tony knows the people that he works with and invests in at a level that most other investors never get to.
