InterWest Partners invests in some of the world’s most promising early stage IT and healthcare businesses. Our Healthcare team invests capital in a wide array of early-stage companies including preclinical- and clinical-stage firms with great potential, as well as companies with commercial-stage assets. The InterWest IT team typically favors funding development-stage companies, but also provides capital to early-stage companies with near-term ROI potential.Although we generally invest in the early stages of a company's development, we evaluate companies on their individual merits rather than their investment stage. We invest an average of $10 to 15 million over the span of our involvement with each company in our portfolio.
