OS Fund
OS Fund is an American venture capital fund that invests in early-stage science and technology companies. Firm. Bryan Johnson created OS Fund in October 2014, a year after selling Braintree to eBay for $800 million. He devoted $100 million from the sale of the mobile-payment processor to establishing the fund. Johnson and Jeff Klunzinger serve as the fund's general partners. The fund draws its name from the acronym for operating system (OS), the software that underlies the basic functions of computers and provides a foundation for other applications. OS Fund focuses on investment  in technologies and platforms in genomics, synthetic biology, computationally derived therapeutics, advanced materials, and diagnostics. In September 2015, OS Fund published the methodology it uses to evaluate investments in the field of synthetic biology. Johnson said the fund publicly released the "playbook" on its website to encourage others to invest in emerging sciences. Origins. Johnson has said he launched the fund in response to a pullback in federal support of research and development, and because of a general reluctance by more traditional venture capital firms to make science-related investments. He also has spoken of a desire to use his  resources to improve the lives of others. Investments.
