Does Grit Actually Matter in a GP — or Is It Just a Good Story?
How I Invest With David Weisburd
· · 46 min · Hosts: David Weisburd · Guests: Larsen Jensen
Summary
Larsen Jensen argues that deliberately choosing hard things is one of the best ways to build resilience, judgment, and long-term advantage, both in elite performance and in venture capital. He ties that idea to his background as an Olympic swimmer and Navy SEAL, saying the point is not hardship for its own sake, but the discipline gained from repeatedly pushing through adversity and discomfort.
He says that same mentality matters at Harpoon Ventures, where the firm backs critical technologies tied to U.S. and allied national interests, including cybersecurity, AI, rare earths, and energy. Larsen says Harpoon’s edge comes from helping founders win government business and from being willing to back non-consensus ideas that can become outlier outcomes. He stresses that venture is a power-law game: the size of the winners matters far more than the hit rate.
The conversation also focuses on startup execution. Larsen says product-market fit requires a 10x better solution aimed at customers with acute pain, but he thinks the team is still the most important factor because great founders are upstream of product and market. He also argues that humility, mentorship, and servant leadership matter, and that the best leaders solicit input rather than impose every decision from the top down.
Key takeaways
- Larsen Jensen says hard pursuits build resilience only when they are tied to a higher purpose, not just suffering for its own sake.
- Harpoon Ventures says it has helped portfolio companies close over $1 billion in total government contracts since inception.
- Larsen says venture is a power-law business where one outlier deal can return the fund multiple times over.
- He argues startups need a 10x solution and a desperate customer cohort before product-market fit can emerge.
- Larsen says the team is upstream of product and market because great founders choose both the problem and the customer.
- He says mental toughness in investing comes from surviving losses, missed deals, and bad decisions without becoming complacent.

How the episode opens
Larson, I'm been very excited to chat. Welcome to the High Invest podcast. Sit to be here.
Thanks for having me, David. So, Larson, you're the founding GP of Harpoon Ventures, which is in the third fun mistake by both A16Z and Lightspeed. And I want to get into this, but before we get into that, you won an Olympic medal as a swimmer in both 2004 and 2008.
You were also a US Navy Seal. And when we last chatted, you talked about embracing things that are hard. What is the benefit of embracing things that are hard?
It's one of the most important things I think I've taken with me through those different career fields and now bring with me into the world of venture capital. As I look at the founders that we've had the opportunity to back, the founders that I admire the most, whether it be Elon Musk and others, they're taking on these challenges that are somewhat irrational, it seems like at first glance, like building a whole new OEM company, electrifying the the car industry, bringing us to Mars, literally replacing NASA, it seems like in many cases with some of Elon's pursuits. And I if I look back at my prior career in swimming, I signed up to for the most difficult races that I could.
The distance freestyle races. I'm sure other listeners who maybe are breast strokers or backstrokers would disagree with me, but I think the things that are most difficult in life are the ones where you feel the most fulfillment. You get to grow as a person.
You get to bring the people around you with that growth as well. And I had that opportunity in the SEAL teams. It's notorious for being the hardest military training in the entire world.
