Manager's Experience

Larsen Jensen (Founder & Managing Partner) founded Harpoon Ventures in 2018 bringing unique operator-investor expertise as former Navy SEAL, Olympic swimmer (representing Team USA), and Captain Sports Hall of Fame inductee. The team operates from San Diego with dedicated focus on the "Freedom Stack" thesis — critical technologies including AI, autonomy, cybersecurity, and advanced manufacturing supporting both national security and global stability. The firm has raised $183M across three funds backed by Andreessen Horowitz veteran Peter Levine, former Olympic swimmer Michael Phelps, and the Illinois Municipal Retirement Fund, with Black Flag Incubator initiative supporting founders navigating US government procurement.
