About The Fund

InterWest Partners is a well-established venture capital firm that began its journey in 1979, focusing on early-stage investments primarily within the IT and healthcare sectors. With headquarters located in Menlo Park, California, they have prudently managed and invested in numerous companies across a variety of industries, including software, communication, financial technology, media, nanotechnology, e-commerce, mobile, retail, manufacturing, and life science. They specialize in Seed and Series A investments with a minimum investment threshold of $10 million, a maximum of $15 million, and an investment sweet spot of around $12.5 million. Throughout its four decades of operation, InterWest Partners has raised $2.8 billion through ten funds, celebrated 97 initial public offerings (IPOs), and witnessed 95 upside acquisitions. InterWest's strategic investment choices during the 1980s and 1990s in IT companies like Xilinx and CIENA, and healthcare firms such as COR Therapeutics and Ventritex have been pivotal in establishing its reputation. Their final fund, IW10, boasts significant achievements with high-profile investments leading to monumental successes, such as Doximity, Canva, Braze, Tesaro, C3.ai, Glaukos, and Labrys. These enterprises have carved niches in areas ranging from digital physician networks to enterprise AI, and from innovative therapeutics for ovarian cancer and eye disorders to a novel treatment for migraines. As of now, InterWest is not actively seeking new investments, indicating a possible transition or pause in their investment activities. However, their legacy of partnering with world-class entrepreneurs to cultivate winning companies remains an integral part of their narrative.
