How to Leverage Domain Expertise — Chris Lovejoy, Notius Labs

Chris Lovejoy argues that winning in vertical AI is an organizational problem solved by domain experts acting as Oracle (directly improving AI), Evaluator (defining metrics for engineers), or Architect (building self-improving systems). Granola's first employee, a writer, reviews meeting notes and tweaks prompts as an Oracle because there is no objectively perfect note. Tandem used decentralized Oracles—doctors per specialty and country—to handle variation in medical scribe outputs. Anteria progressed from Oracle to Evaluator to Architect as prior authorization required measurable correctness and automated learning from usage variation. Lovejoy advises hiring a principal domain expert early, giving them ownership, and hiring for breadth (domain expertise plus adjacent skills like data science or engineering) to avoid slow progress and turnover.
