i/o Ventures

i/o Ventures

i/o Ventures was founded in Mountain View, California, by a group of operators and investors with backgrounds in venture capital and technology startups. The firm's structure is that of a venture capital firm rather than a traditional family office, though it may manage capital for high-net-worth individuals or institutional partners. Wealth origin for the firm's principals is not publicly disclosed. The firm pursues early-stage investments, primarily at seed and Series A stages, across enterprise software, AI/ML, and digital health. i/o Ventures typically leads rounds or co-invests with other seed-focused funds, taking board seats in portfolio companies. The geographic focus is concentrated on the San Francisco Bay Area and Silicon Valley, with occasional investments in other US tech hubs. As of early 2025, i/o Ventures has not disclosed AUM or the number of professionals. The firm maintains a single office in Mountain View, California. No philanthropic or adjacent vehicles are publicly associated with i/o Ventures. A structural differentiator is i/o Ventures' stated emphasis on founder-friendliness and operational support—the firm provides portfolio companies with access to a network of advisors and potential customers. This approach is common among seed-stage venture firms, but i/o Ventures distinguishes itself through a relatively lean team and a focus on deep technical diligence.
