About
We built Matter because coaches were drowning in data and starving for decisions.
Every athlete wears a performance tracker. Every coach has a spreadsheet. Nothing connects them to what the coach actually has to decide on a Tuesday morning. Matter is the layer in between — reading the signals, drafting the change you ask for, and waiting for your approval.
What we believe
Coaches don’t need more data. They need fewer decisions to make alone.
Wearables collect signals by the billion. Program tools organize sets and reps. Neither one tells a head coach which three athletes need a lighter day on Wednesday, or which parent email to send this morning, or whether Jordan is genuinely overreaching or just sleep-deprived.
That judgment call is the job. It happens a hundred times a week, and it’s usually done in a spreadsheet at 6am with cold coffee. Matter exists so the pattern-matching, the drafting, and the admin happen automatically — and the coach spends their hour on the call that only they can make.
How it works
Informed, reliable, intelligent, individualized.
Overnight, Matter reads every athlete on your roster against their own baseline: readiness, sleep, HRV, training load and the check-ins they wrote. It flags who needs you and why, drafts the session change, the program or the message, and grounds each answer in sport science you can click into. By the time you’re in the office the decisions are drafted with their reasons, and nothing is written until you Approve.
Readiness
Know who’s ready.
Daily readiness score for every athlete, calculated from HRV, sleep, strain, training load, and check-ins.
Decisions
Draft what to change.
Session adjustments, deload triggers, risk flags, parent messages, and follow-ups — written, queued, waiting.
Approval
Act in one tap.
One inbox. One tap per action. Nothing runs without the coach approving it — the AI drafts, you decide.
Who it is for
Built for coaches who lose hours to the in-between work.
- S&CStrength & conditioning coaches managing 15–150 athletes who need readiness context and load-sensitive workout tweaks without rebuilding programs daily.
- Skill coachHead coaches and skill coaches who design practices around who’s actually ready to train today, not generic weekly plans.
- ATCAthletic trainers and performance directors who need cross-roster risk flags, return-to-play protocols, and audit-ready documentation.
- ClubClub and multi-sport programs that need multi-coach workflows, parent communication, and roster-wide compliance automation.
Founder
Built by a D1 swimmer turned gym owner who lived both sides of the problem.
Matter’s founder was a Division I swimmer at Colgate, balancing two passions: swimming and lifting. That split led to overuse injuries, coaching decisions that didn’t account for what was actually happening in the pool that week, and training plans that looked great on paper but ignored the body underneath them.
After college he opened a gym and started coaching himself — and discovered the other half of the problem. Truly individualising a session for each athlete, understanding their context, balancing that against admin, programming, and billing for dozens of clients at once is almost impossible to do well. Every coach he talked to was doing it with spreadsheets, guesswork, and 6 AM coffee.
Matter is the tool he wished both sides of that experience had — athletes whose readiness context is actually seen, and coaches who get their evenings back.
