Using customer research and product tests to decide what to build next.
I turn customer research into product decisions, requirements, experiments, and launches for AI products.
I build AI products by talking directly with users, learning how their work gets done, and turning what I hear into priorities, requirements, tests, and launches.
I have used that approach across AI products, marketplace strategy, education programs, investment analysis, and a business I founded and operated. At TwelveApart, I publish enough of the work for others to see how a decision was made and what happened next.
Currently
Leading product from thesis to launch at Pier — discovery, AI product strategy, requirements, roadmaps, QA, and a multi-location pilot rollout with multi-state operators.
