Overview

What they do
Founded in 1986, ARCH Venture Partners is a leading American venture capital firm known for co-founding and investing in companies based on breakthrough science, primarily in the life sciences, information technology, and physical sciences sectors. The firm's origins trace back to a technology commercialization effort at the University of Chicago, and it has since grown into one of the largest and most influential early-stage biotech investors. ARCH is distinguished by its strategy of partnering with leading scientists and research institutions to build companies from the ground up, often taking significant scientific and market risks. Their reputation in the ecosystem is that of a bold, contrarian, and hands-on company builder, willing to back transformative technologies with substantial capital over the long term.

What they look for
ARCH's investment thesis is centered on backing bold, platform-level science at its earliest stages and helping to translate it from the lab to the market. Their philosophy, consistent for over 38 years, is to "bet on great science and great teams to build breakthrough companies." They focus on creating and investing in companies with disruptive science that can prevent, detect, and treat disease, as well as those with transformative technologies in physical sciences and IT. They are contrarian, imaginative risk-takers not interested in following trends.
