About Us

Built on the Shoulders of Giants

It all started in 2015—a conversation over a podcast question, “Can we combine technology with exercise science to reduce coaching friction?” In that moment, Paul Laursen and Steve Brown planted the seed that would become Athletica AI. A passionate team of scientists, coaches, and engineers came together to answer the same question every athlete asks: “What training should I do today?”

Our Why?

Every athlete deserves training that works for life. Athletica’s mission is clear: revolutionize athletic training using AI-powered coaching grounded in first-principle sports science to support athletes and coaches alike in making smart, responsive decisions.
