Calm Ventures

Calm Ventures is an early-stage venture investor founded in 2020 by Zachary Ginsburg and based in Los Angeles, California, with a secondary presence in Idaho. It operates primarily as a private syndicate on AngelList, deploying capital through deal-by-deal SPVs and a rolling fund backed by over 1,500 LPs, and reportedly manages roughly $140M. Calm has backed 500+ companies and typically invests from pre-seed through Series B, occasionally participating in pre-IPO rounds, frequently co-investing alongside firms such as Andreessen Horowitz, Founders Fund, 8VC, and Khosla Ventures. Though broadly industry-agnostic, it concentrates on B2B software, AI, biotech, and frontier hardware; deep-tech holdings include Anthropic, d-Matrix, Impulse Space, Stoke Space, Shield AI, Epirus, Bear Flag Robotics, and Agility Robotics. Because Calm invests via syndicated allocations rather than fixed checks, deal size varies by round; founders typically engage through AngelList or a warm introduction, with diligence often concluding within a few weeks.
