Joshua Posamentier brings deep technical hardware experience from building semiconductors and wireless chips at Intel, National Semiconductor, and TI before moving into climate-focused venture investing, giving him unusually strong expertise in evaluating complex hardware and systems beyond just software. He holds a physics degree from UC Berkeley, dual MBAs from Columbia and Berkeley Haas, and has over 50 patents, while explicitly focusing on engineering risk rather than science risk and avoiding business models that depend on long-term government subsidies.
