Phil Inagaki spent 15 years founding and running deep tech companies in semiconductors, energy, advanced manufacturing, and AI before moving into venture at 38, and he still gets directly involved after investing, co-founding Amperesand and serving as its interim CEO while leading Xora Venture Labs. His investments tend to focus on physical infrastructure bottlenecks like transformer supply for EV charging, new storage standards for utility-scale energy, and rebuilding AI networking infrastructure from the ground up, reflecting a consistent interest in solving hard, physical engineering problems rather than backing software alone.
