InterWest Partners

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