Derrick St. Aubin

Founder & Principal

Derrick has been building production AI since the pre-LLM era — recommender systems, vision pipelines, and now agents. He runs Just Think AI as a deliberately small, senior team that ships in two-week sprints and tells you when not to use AI. Background in computer science, ten-plus years across early-stage startups and regulated enterprises.
