About Mentalyc

We redesign therapy—and we don’t take no for an answer.

“Impossible” gets us excited. We chase hard problems, missing questions, and truths no one’s cracked. We think big, fight hard, and stare fear in the face.

Mentalyc started in 2021 when analyzing therapy sessions seemed untouchable. Investors passed. We proved them wrong. We grew on revenue, product-market fit, and relentless experimentation.

Today we lead the fast growing AI scribe therapists market. We have millions in revenue from thousands of clients. And we are just getting started.

We’re building a future where therapy is measurable, effective, and radically transformed. We won’t stop until we get there.
