Experience matters

Decades of Experience

As entrepreneurs ourselves, we have unique access to corporate partners, key innovators in academia, and other entities that represent likely eventual homes for our investment projects. We're there, from idea to exit.

We are investors, inventors, business strategists, founders and serial entrepreneurs. Our leadership team has a long history together, investing in and launching dozens of early-stage life science companies. We're located in regions with a rich concentration of research, discovery and venture capital investment, and we're known by leaders of portfolio companies for the expertise and deep support we provide.
