This high level of personal commitment enables us to deliver on our fundamental promise to the entrepreneurs we back: to add value beyond the capital we contribute. Our commitment to our investors and our longstanding record of success has earned InterWest a reputation as one of Silicon Valley’s leading venture capital firms. An InterWest general partner serves as a director for 85% of the companies in our portfolio, often continuing to serve even after the partnership’s investment in the company has been returned. We maintain relationships with our portfolio companies for an average of five years and in some cases for ten years or more.

InterWest is the lead investor in more than 70% of the investments we make, reflecting our ability to marshal resources and organize financings on behalf of our portfolio companies. In 2014, InterWest made 22 investments and managed more than 100 active investments. InterWest is currently investing in InterWest X, a $650M fund. With more than 200 years of operating and investing experience, InterWest has raised $2.8 billion, completed 80 IPOs, and participated in 81 upside acquisitions.
