## About CiRi Ventures

CiRi Ventures is a climate and deep tech investment fund led by operators who back builders, staying with founders early and for the long haul. The firm has deployed over $100 million into hard tech, backing more than 30 companies from pre-seed through Series B+.

CiRi's focus spans batteries, fusion, solar, hydrogen, robotics, chemicals, and AI, investing in capital-intensive, deep-tech companies where manufacturing and scaling to commercial production, not just scientific proof of concept, represent the primary bottleneck to real-world impact.

Its portfolio includes Terraform Industries, Lyten, Natrion, Marathon Fusion, Nevoya, Cosmic, Newlight, and Bees & Bears, among 30+ companies. The firm's philosophy, "Hack to Win," centers on squeezing supply chains, compressing lead times, and cutting costs to push deep-tech science into commercial reality.

CiRi's investment approach is intensely hands-on, with founders describing the team as rolling up their sleeves on financial modeling, growth hacking, and operational problem-solving rather than writing a check and waiting, prioritizing founder-aligned partnership over a formal, process-heavy pitch and diligence structure.
