Investing to secure American technological leadership for future generations.

Our mission is to back bold leaders shaping the next era of American innovation

Founded in 2018 by a two-time Olympic medalist and former Navy SEAL, Harpoon was built on a simple belief: technology will define geopolitics.
Our first backers—a16z and Lightspeed—bet on our vision. Today, we’re anchored by the nation’s top pensions and endowments, including a leading first responder pension fund.
We’ve worked side-by-side with our founders to secure nearly $1B in U.S. government contracts—spanning non-dilutive grants to $100M+ programs of record.
At Harpoon, we’re more than investors--we’re your tactical advantage.

The "Freedom Stack" is a set of foundational technology critical to national security and prosperity.

Investing in these areas is not only essential to restoring American technological leadership, but also ensuring strategic advantage for future generations.

We back groundbreaking technology companies in AI, cybersecurity, software infrastructure, and deep tech. Harpoon invests in the risk takers, outliers, pioneers, and innovators building category defining businesses.
