How I Invest with David Weisburd

What if AI makes software abundant and shifts venture capital’s biggest opportunities into the physical world?
Leo Polovets is a General Partner at Humba Ventures, an early-stage deep tech fund investing across robotics, defense, energy, manufacturing, and other physical industries. Leo explains why AI is commoditizing software, why hardware may capture more value as a result, and why some of the best opportunities are hiding in industries with almost no startup competition. We also discuss how to underwrite deep tech before revenue, what separates exceptional founders, the infrastructure bottlenecks created by AI, and why the biggest risk to deep tech may be its dependence on continued funding.

What happens when autonomous underwater vehicles become cheap enough to manufacture at scale?

Nelson Mills is the Founder of Vatn Systems, a defense technology company building autonomous underwater vehicles. Nelson explains why undersea autonomy has lagged aerial drones, how advances in AI, navigation, manufacturing, and autonomy are changing the economics, and why Vatn is building lower-cost systems designed to operate at scale. We also discuss raising $85 million for a hardware startup, the rise of asymmetric warfare, lessons from Anduril, and what it takes to build a new defense prime.

What if AI makes the founder more important, not less?

John Borthwick is the Founder of betaworks, the startup studio and venture firm behind companies including Giphy, Dots, bitly, and TweetDeck, with investments in companies including Twitter, Tumblr, Kickstarter, and Hugging Face. We break down why John now puts more weight on founders than products, how betaworks identified Hugging Face before transformers reshaped AI, and why he believes the biggest opportunity is moving toward the AI application layer. We also discuss open-source AI, AI security, the changing nature of work, and why John believes AI was discovered rather than invented.

What did Steve Jobs understand about building great companies that most founders miss?

Steven Rosenblatt is Co-Founder and General Partner at Oceans, a seed-stage venture firm based in New York City. Drawing on more than two decades as an operator and investor, including his time at Apple and Foursquare, Steven shares what he learned working directly with Steve Jobs, how he separates ambitious founders from delusional ones, what drew Oceans to Etched, and why AI is creating a technology cycle unlike anything he has seen before.

What if the future of warfare is determined by who can innovate faster, not who can spend more?

Ethan Thornton is the Founder and CEO of Mach Industries, a defense technology company he started after dropping out of MIT. We break down how Mach went from experimenting with roughly 20 technologies to becoming a multibillion-dollar company, why Ethan believes asymmetric technology is reshaping modern warfare, and how Pentagon procurement is evolving. We also discuss China and Taiwan, lessons from Ukraine, autonomous warfare, recruiting exceptional talent, taking risk, and why Ethan believes great founders should empower their teams rather than make every decision themselves.
