What Theory Ventures does
Theory Ventures is an early-stage venture capital firm founded in 2022 and based in Portola Valley, California, that invests primarily in AI-focused software companies. The firm concentrates on AI infrastructure, data platforms, agentic enterprise software, security, and generative AI applications, and is led by founder and general partner Tomasz Tunguz, a recognized commentator on AI infrastructure economics. Across 2025 and 2026 Theory has both led and participated in approximately eleven funding rounds totaling roughly $484 million of round capital, including leads in LanceDB ($30M Series A), Doss ($18M Series A), Dropzone AI ($37M Series B), Aampe ($18M Series A), Koah ($20.5M Series A), and BackOps ($26M Series A), and participation in larger rounds such as Omni's $120M Series C at a $1.5 billion valuation.
The firm's business model follows standard venture capital economics — it raises capital from limited partners and deploys it into portfolio companies in exchange for equity, generating revenue primarily through management fees and, on successful exits, carried interest. Neither fund size, AUM, fee structure, nor LP composition is publicly disclosed. Theory also pursues ecosystem-building activities such as co-hosted founder networking events during AI Council week in San Francisco, and the firm operates with a small team of 1-10 employees, consistent with a lean, thesis-driven emerging manager. The firm also does business as "Theory VC."
