This episode of Skin in the Game features a deep, candid conversation with Felix Hartmann, founder of Hartmann Capital on what it really means to build and invest at the frontier of technology.

Felix’s story starts long before hedge funds and venture capital. He moved to the U.S. from Germany during the 2008 financial crisis, initially planning to stay for just a year. That plan changed quickly. Early exposure to markets, coding, and emerging technology led him down a path of trading, crypto infrastructure, and eventually founding his own firm and launching Hartmann Capital the same day he signed his first apartment lease.

A major theme throughout the episode is conviction through firsthand experience. Felix doesn’t invest from a distance. He tests products, uses them extensively, and looks for signals that can’t be captured in a pitch deck. Whether it’s VR games, smart glasses, or brain computer interface technology, he believes the clearest insight comes from being a real user and understanding how a product fits into daily life.

The conversation explores why Felix shifted away from liquid crypto trading and toward long-term venture investing in frontier categories like VR, spatial computing, wearables, and neural interfaces. He explains how hardware limitations slowed VR adoption, why smart glasses may be closer to a breakout moment, and how enterprise use cases often precede consumer adoption. The discussion also touches on sub-vocal communication technology that allows people to interact with devices without speaking out loud and why it could fundamentally change how humans interface with machines.

Saxon and Felix also discuss the realities of investing on the “bleeding edge,” where traditional metrics don’t exist and patience is required. Felix breaks down how power-law outcomes often come from non-consensus bets and why underfunded categories tend to attract the most mission-driven founders.

The episode closes with reflections on geography, talent, and ecosystem building from Florida’s role in capital formation to the continued importance of Silicon Valley and Los Angeles for early-stage innovation.
