InterWest Partners

Our business is about helping entrepreneurs — the people who change the way we live and work by creating new products and services — convert their ideas and ambitions into reality. As an investor and partner, InterWest provides valuable industry, strategic, and corporate development expertise, as well as capital resources, to help young companies succeed.

Investment Size and Stages

InterWest invests an average of about $7 - 15 million over the span of our involvement with each company in our portfolio. We invest in companies through the full range of venture investment stages, and investments may be staged over several rounds of financing. Although we generally begin our involvement in the early stages of a company's development, we pursue attractive opportunities based on their individual merits rather than their investment stage.

Leadership and Commitment

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. We maintain relationships with our portfolio companies for an average of 5 years and in some cases for 10 years or more. 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.

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.
