Investment thesis
Rain Capital invests at the pre-seed, seed, and Series A stages, backing companies through their earliest critical growth phases. The firm focuses on three converging and compounding domains: AI, cybersecurity, and healthtech. It views AI as an accelerant of innovation, cybersecurity as the layer protecting intelligent systems, and healthtech as the application of both to improve human outcomes. Sourcing is expert-led and community-assisted, leveraging relationships with exceptional founders and leading academic institutions to identify opportunities early.
