Built by coach Kelly Sims.
17+ years as an elite soccer coach, with deep industry connections ranging from youth to professional leagues.
A former Arsenal Women’s youth player coached by current USWNT Head Coach Emma Hayes, Kelly has spent 17+ years in elite youth coaching and 5+ years with U.S. Youth National Teams.

She holds a B.Sc. in Coaching from Cambridge and multiple U.S. Soccer licenses.
C2X grew from her work studying how coaching communication shapes learning — and from wanting every coach to get the feedback she wished she’d had.

Who is C2X for?
Individual coaches who want to improve, and clubs that want to develop their whole coaching staff.
What do coaches need?
An iPhone with the C2X app. A clip-on mic gives the best audio. This is the one we use. One thing matters most: check the mic is recording before every session — no recording, no feedback.
