our focus

Innovation in life-science and resource-driven sectors

We invest deeply and strategically in companies with innovation at their core. We identify companies that reduce and evolve the consumption of the planet’s limited resources, including water, food, energy and natural resources and seek opportunities in the life-science sector to improve patient outcomes by developing innovations in biopharma and medical devices.

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
