About
We’re building the brain behind great coaching.
Why we built it
A trainer with six clients knows all six. Whose knee acts up in the cold, who travels every March, who says they slept fine and did not. They hold it and adjust on instinct, and the coaching is excellent.
At thirty clients that memory runs out, and the data keeps arriving anyway. Harlen carries the memory and does the reading, so the judgment stays where it belongs.
Who’s behind it
We met in high school and started Harlen in early 2026. Between us we have held data and AI roles at Tesla, UPMC, Care Hospice, and Atlas Copco, and we have both worked inside Division I football programs, Kai at Pitt and Daniel at Virginia.
We do the same job here. We both write the software, we both talk to trainers, and every decision in the product traces back to one of those conversations. The first version won Conway’s Best AI for Decision Support at Carnegie Mellon’s TartanHacks, and Pitt’s Big Idea competition put $5,000 behind it a few months later.
Harlen is in beta with its first rosters in Pittsburgh, and access starts with a short call with one of us.
