Summary
Loïc Houssier, VP of Engineering at Superhuman (the email client Grammarly acquired for $825M in July 2025), explains how his team retrofitted AI features into a product whose entire brand promise is sub-100ms speed. He breaks down the model-routing strategy, the eval framework his PMs own, and why his team auto-drafts every reply but refuses to auto-send any of them.
