Harpoon Ventures Announces $155 Million Fund IV Close

Harpoon Ventures, the early-stage venture capital firm founded by former Navy SEAL and Olympic medalist Larsen Jensen, recently declared the final close of its oversubscribed Fund IV with $155 million in committed capital. This brings the firm's total assets under management to over $450 million. Fund IV will uphold Harpoon's strategy of collaborating with founders at the frontier, constructing mission-critical technologies in artificial intelligence, deep tech, and defense. Larsen Jensen stated,

'The next generation of companies will not just build great products – they will solve problems that matter to our nation's long-term competitiveness.' The firm has built a platform to assist founders in converting government adoption into a growth engine, helping them unlock over $1 billion in government contract opportunities. Fund IV will further support Harpoon's Black Flag program, which invests in companies at the earliest stages with capital, mentorship, and go-to-market acceleration.

Harpoon's limited partners include leading U.S. pensions, endowments, and family offices. Harpoon Ventures, established in 2018, invests across artificial intelligence, deep tech, and defense, providing founders with hands-on operational support.
