For pro teams, federations, and performance staff
Build your team's own performance tools. Ship them in an afternoon.
A private library of small, internal analytics tools, built around your roster and hosted by us. Your athletes consent once. Your coaches and analysts build and open every tool from a single dashboard.
Question asked at the morning standup. Tool live before lunch.
What it replaces¶
The data question that could shape Sunday's start line shouldn't wait until Monday. Today it usually does, because the answer lives in:
- The Monday-morning spreadsheet, rebuilt by hand every week.
- The BI dashboard that's a season behind.
- The Jupyter notebook only the intern who left last year could run.
- The data person who's three asks deep in their queue.
One team account replaces all of it: a growing library of small tools that answer these questions the day you ask them, and keep answering them all season.
How it works¶
Athletes consent once, to the team
One screen grants your whole staff access to an athlete's data. Every new tool you build inherits it automatically. Not per tool, not per login.
Your team builds the tools
An analyst writes the code, or a coach drives an AI agent with our skills. One CLI command deploys it. We host it.
Everyone opens one dashboard
A single URL, signed in with the team account, the whole library in one place. No tool-by-tool login for anyone on staff.
Access stays locked to your people
Staff see staff tools. Athletes never see coach-only ones. Roll someone off the team and their access ends immediately.
What your team can build¶
Small tools, not simple tools. Small means scoped to one question, not stripped of power. Every tool talks to the full SweatStack API: years of longitudinal data in one query, physiological profiling, training-zone math, streams normalized across every wearable your athletes use. Small enough to live on a coach's phone. Powerful enough to answer what used to take six months.
A few we built to show what's possible, each entirely by prompting an AI coding agent, each well within one afternoon:
-
Power-Duration Studio
Compare power-duration across athletes, date ranges, and fatigue states.
-
Torque Lab
Analyze and periodize torque training across a training block.
-
Paper Playground
Apply the results of a published paper to your own athletes' data.
-
Longitudinal data demo
Query and chart years of activity data in a single call.
Who it's for¶
- Professional sports teams running daily decisions off a shared roster.
- National federations coordinating data across programs and squads.
- College and university performance staff supporting athletes at scale.
- Any small group answering recurring questions about the same athletes.
Your data stays in your control¶
Your athletes' data is one of the most valuable things your team holds, and one of the most sensitive. Which is exactly why it belongs on secure, professionally run infrastructure built to protect it. Keeping it that safe is a job in its own right, and your performance staff have better ones.
With SweatStack, that's exactly what you get, and the data stays yours:
- You decide who sees it. Athletes grant access to your team, not to us. You control what each person on staff can open, and you can revoke access, export everything, or delete it outright at any moment.
- Used to run your tools, and nothing else. No resale, no sharing with other teams, no second life for your data. That's set in your agreement, not just promised on a page.
- Secured, monitored, and backed up around the clock. Your data lives on hardened infrastructure in the EU, maintained full time, so it stays protected as staff and sponsors come and go.
None of this rests on trust. You sign an agreement with us that says so in plain language: your data is yours, now and if you ever leave.

Two ways to build your library¶
-
Your team builds them
We teach your team the workflow, whether they're analysts or coaches driving coding agents, and help ship the first tools. From there the library is yours to grow, and we're on call when you need us.
-
We build them with you
Prefer to hand it off? Tell us what you want in the library and we'll build it with you, then keep extending it as your questions change through the season.
Open for launch partners¶
Launch partners help us shape the team layer to their workflow, with weekly input on what we ship next and our team alongside theirs as it lands. Limited spots available. Email us.
