From a Radio Shack in eastern Kentucky to three AI ventures, Rao has followed one stubborn question: what kind of machine should intelligence run on?
Rain AI wanted to make computers think more like brains. Two chip runs taught it a less romantic lesson: the smartest architecture is the one you can build.

The CyberSwarm founder turned failed ventures, 16,000 emails and an unfashionable bet on analog hardware into a patient campaign to make AI learn locally, with less energy and no cloud required.
CyberSwarm is a neuromorphic engineering company building brain-inspired, memristor-based hardware that lets machines learn and adapt locally, at the edge, without the cloud. Founded in 2017 by Mihai Raneti and headquartered in San Mateo, California with R&D roots in Ploiesti, Romania, the company is developing a neuromorphic System-on-a-Chip for cybersecurity and energy-efficient AI, positioning its architecture as a new computational layer between conventional digital systems and quantum computing. In May 2026 it raised a $50 million Series A to scale toward commercial deployment across automotive, aerospace, defense, healthcare and robotics.
