In this episode of Tank Talks, we sit down with Brett Gibson, Managing Partner at Initialized Capital, to explore how the world of venture capital is being reshaped by advancements in AI, crypto, and space technology.

Brett’s career has been anything but conventional. From co-founding Posterous with Garry Tan (which was later acquired by Twitter) to rebuilding the platform as Posthaven, and reengineering Y Combinator’s internal software systems, he’s seen it all. Today, as Managing Partner at Initialized Capital, Brett is spearheading investments in emerging sectors like AI infrastructure, crypto technologies, and even asteroid mining.

In this conversation, Brett reflects on his journey of building and scaling startups, the transformation of Initialized Capital following its 2024 restructuring, and his thoughts on why AI is outpacing crypto in shaping the future. He also shares his perspective on moonshot investments, including AstroForge’s mission to mine platinum from asteroids, and offers insights into how founders should navigate an era of rapidly evolving technology.
