Harpoon Ventures

Harpoon Ventures is led by Larsen Jensen, a former Navy SEAL and Olympic swimmer, who brings a "warrior ethos" to investing in what the firm calls the "Freedom Stack"—foundational technologies like AI, autonomy, cyber, space, and energy that are critical to American national security. The firm specializes as a bridge between early-stage startups and complex government buyers, with a team of former national security operators and acquisition experts who help founders navigate procurement and dual-use commercialization beyond typical venture capital support.
