We are guided by seven investment principles that have proven successful through multiple funds:

  • Focus on seed and early stage opportunities. We will invest in an idea described in a laboratory notebook, an enabling technology, or a proven management team. Our involvement typically begins well before most venture capital firms, at the point of innovation. Innovation investment is what we do.

  • Concentrate on breakthroughs and fundamental advances in life sciences, physical sciences, and information technology. Technology is our focus. View a list of portfolio companies by technology focus.


  • Maintain an on-the-ground presence in geographic areas that are underserved by early stage venture capital but contain great centers of basic research and an active community of technologists. We maintain a national scope with a regional focus. Our offices in San Francisco, Austin, Chicago, and Seattle reflect the concentration of portfolio companies in the southwest, midwest, eastern seaboard, and northwest.

  • Maintain our special competence in building companies from products originating in academic and research labs. True to our roots, we build relationships with key scientists and technology transfer personnel at affiliated research institutions. We have also worked with major corporations to organize companies around their research initiatives. When it makes sense, we will unite science and technology from multiple sources to form a company. Learn more about ARCH affiliates in science and academia.

  • Adhere to an investment model that has proven successful for ARCH. Our approach is to invest conservatively at first to reduce or extinguish risk and then lead or co-lead additional rounds of financing all the way to liquidity. We syndicate early with familiar partners and utilize non-equity capital often available to early stage companies. Learn more about ARCH's strategic alliances.

  • Lend our considerable business strengths to assist our portfolio companies in the earliest stages. Our practice is to play an active board role from the time of initial investment to liquidity, and occasionally post liquidity. We will step in as interim executives, if necessary, until the management team is complete and actively help our portfolio companies staff their executive teams. We also cultivate a cross-section of business relationships with our strategic and financial partners that can be useful to our portfolio companies. Explore our individual portfolio companies.

  • Carefully maintain internal partnership cohesiveness. As partners in the truest sense, it is our practice to collaborate on our investments. Although more demanding than other partnership models, this intensive alliance has ensured careful decision making and superior results for our partners. We are known for our collaborative approach and sense of fair dealing. View the biographies of ARCH managing directors, principals, venture partners, and associates.
