In this episode of the Tacos & Tech Podcast, Neal Bloom sits down with Larsen Jensen, former Olympian, Navy SEAL, and now Managing Partner of Harpoon Ventures, an early-stage venture firm backing founders building in the national interest.

Larsen shares the journey from serving Team USA to launching a venture fund focused on what he calls the Freedom Stack - critical technologies like AI, autonomy, cybersecurity, and advanced manufacturing that shape not just industry, but national security and global stability.

They explore how Harpoon was early to the intersection of tech and geopolitics, why San Diego is uniquely positioned to lead in hardtech and defense innovation, and how founders can better navigate the path to working with the U.S. government through Harpoon’s new initiative: Black Flag Incubator.

Key Topics Covered:
