For Clubs, Coaches, and Athletes
Coaching used to evaporate. Now every word builds.
You give feedback in real-time, then it’s gone. Coach Sidekick captures every session, attributes every cue to the right player, and turns what would otherwise evaporate into compounding development: drills for players, analytics for coaches, visibility for directors.
Built by an education researcher and an MLS veteran who coaches youth soccer today.
Players retained 57% of their coach's feedback, measured immediately after it was given.
In a study of 342 youth soccer players, only 1 in 3 pieces of feedback was reproduced completely. Coaches give dozens of cues every session, and most fade before players can use them. Coach Sidekick makes sure they don't.

How it works
From the pitch to every player.
One 51-minute practice produced 131 moments of coaching feedback for 12 players. Here's how a single moment reaches the player it was meant for.

Transcribe
Coach Sidekick turns the audio into a timestamped transcript. At 33:05, one instruction lands in the middle of a scrimmage.
Good skill, Diego. That's a goal play. Settle it down, settle it down. Use your body, use your body. Settle it down. Make it big. Now. Head up, Chris. Head up, Chris. Always know where that pressure is. Turn.
03
Attribute
The AI untangles who each moment was for and classifies it. This one is Christopher's. Nothing goes out until you review and approve.

Player Development
Players and families finally see what coaches see.
After every session, each player gets a personalized digest: what their coach noticed, where they're improving, and what to focus on next. It builds into a development record that compounds session by session, so families see real growth, not just practice schedules.

Actionable Drills
Feedback without a next step is just noise.
Every piece of coaching feedback gets matched to specific drills with focus points and coaching tips, drawn from a library of 357 drills tagged to a 168-skill taxonomy. Players don't just hear what to improve. They know exactly how to work on it.

Tactics Engine
Draw the play. Watch it run.
Build any drill or pattern on the tactics board, animate it step by step, and export it to share. The clip here is a 7v5 switching-the-point-of-attack game: possession starts locked on the left, a long diagonal switches the field, and the move finishes in the open corner.

See patterns you'd never catch in the moment.
Track how your attention is distributed across players and which feedback types you lean on. After each session, the private Session Debrief mirrors where your attention actually went, so you can develop as a coach, not just your players.

Who we are
Built by an education researcher and a professional player.
Coach Sidekick was founded by an education researcher who studies how people learn and develop, and an NCAA champion and MLS veteran who coaches youth soccer today. We built this because we've seen the gap from both sides: the research and the field.

One practice produced 131 pieces of feedback.
Yours will too. We're working with a small group of founding academies, and every one is onboarded by the founders. If you coach youth soccer, we'd like to work with you.
