Why are humans — not models — still the biggest bottleneck to AI progress, and what happens when that bottleneck becomes a business? In this episode, I talk with Ali Ansari, Founder and CEO of micro1, about the hidden layer powering today’s AI breakthroughs: high-quality human intelligence. Ali explains how micro1 pivoted from an AI recruiting startup into a critical data infrastructure company for frontier AI labs, why expert-generated data is now the limiting factor in model performance, and what needs to change for AI agents to actually work in production. We also explore how focus, market timing, and ruthless prioritization enabled micro1 to scale more than 30× in a single year.

Highlights:

• Why AI progress is still overwhelmingly driven by humans
• The shift from pre-training to expert-level post-training data
• Why AI agents fail in production despite great demos
• Evaluation frameworks as the missing layer for agents
• How micro1 serves frontier labs and Fortune 500 enterprises
• The hardest pivot: firing customers to focus on the right market
• Why market selection matters as much as product quality
• How investors are using AI to gain workflow-level edge
• Humans as operators of agents, not coworkers
• How focus became micro1’s biggest competitive advantage
