OS Fund

OS Fund, based in Chicago, is a venture capital firm founded by Bryan Johnson, a serial entrepreneur best known for founding Braintree, which was acquired by PayPal for $800 million. The firm's core mission is to invest in entrepreneurs, inventors, and scientists who are "rewriting the operating systems of life" to benefit humanity. This unique thesis positions OS Fund at the forefront of deep technology and frontier science investments.

The firm's investment focus spans a wide array of groundbreaking sectors, including synthetic biology, artificial intelligence, robotics, new materials, space exploration, and human augmentation. They seek out companies that are developing fundamental technologies with the potential for transformative impact across multiple industries. OS Fund emphasizes long-term vision and supports founders who are tackling complex, foundational problems rather than incremental improvements.

OS Fund primarily targets early-stage companies, typically participating in seed and Series A rounds. The firm has demonstrated significant capital commitment, having successfully raised at least three distinct funds, each reportedly sized at $100 million, bringing their total capital under management to approximately $300 million. Their typical initial investment ranges from $500,000 to $5 million, reflecting their strategy of providing substantial early capital to highly ambitious ventures. This approach allows them to support companies from their foundational stages through significant growth milestones, fostering innovation in critical scientific and technological domains.
