About Susa Ventures
Susa Ventures invests at seed in software and AI companies.
Susa Ventures was founded in San Francisco in 2013. Altss names Leo Polovets, Chad Byers and Eva Ho as founders. TechCrunch reported in June 2014 that the firm had raised a $25M seed fund, and that it had four operating partners: Ho, Polovets, Byers and Seth Berman. Byers is co-founder and general partner. Misha Gordon-Rowe is a partner. According to a third-party profile he joined in 2020 after working at Funding Circle US, and he is named on the Memories.ai and Euka investments. Other databases also list Pratyush Buddiga and Derick En'Wezoh on the investment team.
Susa's Fund V announcement lists the AI areas it wants to back. They are alternative AI architectures beyond LLMs, custom enterprise software, AI research assistants for science, engineering and medicine, and AI supply chain. It also lists energy, consumer applications and risk management. Susa led the $8M seed round of Memories.ai in July 2025. That company builds visual memory for AI. Susa also co-led a $5M seed round in Euka, a platform that helps brands recruit and manage TikTok Shop creators. On the Lounge deals desk, the firm's recent AI activity includes Physical Superintelligence (Seed, $58M, 2026-09) and Volantis (Series A, $88M, 2026-10).
Susa focuses on pre-seed and seed. Its $125M Fund IV was announced for seed investments of $1M to $2M. The same announcement covered a $250M Opportunities II fund for Series B and C checks of $10M to $15M, mainly into existing portfolio companies. CB Insights lists Fund V at $175M, closed on 2025-03-21. Third-party directories give a wider range of $500K to $5M and say the firm leads rounds. Susa has not confirmed that range on a source I could check. Tracxn's count shows most of its recorded deals are seed, with some Series A.
