About Harlen
We’re building the brain behind great coaching.
We build software that helps coaches keep up with their clients between sessions.
Why we built it
A trainer with six clients knows all six. Down to whose knee acts up in the cold and who says they slept fine when they did not. They hold all of it in their head and adjust on instinct.
As a roster grows, the data keeps arriving. Harlen brings client history, training, and check-ins into one workspace so the coach can see what needs attention and decide what to do next.
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 each write the software and 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.
