Larsen Jensen is a two-time Olympic medalist and former Navy SEAL who now runs Harpoon Ventures, where he helps commercial infrastructure, security, and AI companies expand into government markets—his portfolio companies have closed roughly $500 million in government deals. He built Harpoon around the early thesis that AI and deep tech would have "space-race-level" national security impact, positioning the firm as a hands-on partner that actively helps founders navigate government contracting rather than just providing capital.
