Our Story.

C2X was born from the vision of Kelly Sims, former Arsenal Women’s youth player coached by Emma Hayes. With 17+ years in elite youth coaching and 5+ years with U.S. Youth National Teams. She’s led the STA Girls Academy program to back-to-back national finals—winning the 2025 Champions Cup National Title and was an assistant during the CONCACAF U15 Championship (2021) for the U.S Soccer WYNT. She holds a B.Sc. in Coaching from Cambridge and multiple U.S. Soccer licenses.

Kelly is determined to revolutionize coach development. Our journey began with a simple observation: there is a significant gap between academic research in coaching theory and its practical application on the field.

By combining evidence-based research, real-world coaching experience, and cutting-edge technology, we set out to create a platform that accelerates coach growth and provides a pathway for continued education.

Today, C2X stands as the culmination of years of research, development, and collaboration with leading experts in coaching science, sports psychology, and artificial intelligence. We're proud to be at the forefront of a coaching revolution—empowering coaches to excel and, in turn, unlocking greater player development.
