Prolog Ventures

Venture capital firm specializing in life sciences. Since launch in 2001, they have supported more than 25 young companies. Prolog invests in traditional healthcare opportunities as well as emerging areas such as nutrition, wellness, and green technology in which we’ve built one of the largest portfolios in the country.

The firm was created by people with both investment know-how and direct experience in getting new ventures off the ground. They use this expertise to invest in what they know best: exceptional opportunities in their early stages. And then we take an active, ongoing role in helping entrepreneurs develop the right strategy, team, and connections to succeed.
