In this episode, Alex and Todd Sorrel (CEO of 6lock) dive deep into what it takes to build a championship culture in an industry that's never been known for it. From owning 100% of your infrastructure stack to understanding why 99.999% of payments are boring (but that 0.001% creates all the value), this conversation is packed with insights for anyone building in fintech or serving private markets.

Key Topics:
• Why Alex left Stanford 5 months before graduation to join Column
• The simple framework for early-stage companies: big market, big problem, great team
• How Column bought a bank and rebuilt the core from scratch
• Why "culture eats strategy for breakfast, lunch, and dinner"
• The 0.001% game — why all the value in payments lives in the edge cases
• Column's measured approach to AI in banking infrastructure
