Slingshot is a wearable sensor pod for basketball. Session Load Score, sprint counts, jump metrics, and intensity zones — the analytics pro teams pay $800+ per unit for. Built for the trainers and coaches those platforms were never made for.
5 design partner slots for Summer 2026. Fall 2026 waitlist open.
Catapult and STATSports exist. They work. Programs that run professional academies and D1 teams use them. But at $800+ per unit, $3,600 for a 10-player team on a 2-year contract, with software built for sports scientists — they've never been an option for basketball trainers, AAU programs, or high school coaches.
So trainers go by feel. The eye test works — until a parent asks you to prove it. Slingshot gives you the receipt.
Slingshot is built for the 99% of basketball programs Catapult will never serve.
The Session Load Score tells you exactly how hard each athlete worked. Built from sprint intensity, jump data, movement zones, and heart rate context — paired with the trainer tools you'll actually use.
One composite number per player per session. Built from sprint intensity, jump data, and movement zones. The single metric that tells you who worked and who didn't — and the one your parents will text their spouse about when it goes up.
Every athlete, every session, on one iPad. Compare players at a glance. Flag who's pulling back. Spot trends before parents ask. The tool you wish you had at 5pm after a 15-kid day.
Real-time data on your iPad as the session happens. See who's spiking, who's coasting, who needs a break — without stopping to look at a clipboard.
Auto-generated summary of each athlete's week, branded with your gym's logo. Session Load trend, standout sessions, recovery notes. The artifact that closes the renewal conversation.
Every jump tracked. Vertical measured session by session. The one number every HS recruit obsesses over — and every parent wants to see go up.
Every explosive burst logged automatically. Basketball-tuned for 5-to-10 yard bursts, not soccer-style distance. Know which players are pushing hard and which ones are coasting.
Green, yellow, red. A simple breakdown of how each player spent the session. Know who's been grinding at max intensity all practice — and who barely broke a sweat.
Export every metric, every session, every athlete to CSV with one click. Your data is yours. No lock-in. No paywall. We're a tool, not a hostage situation.
Live session indicators, shot detection, leaderboards, practice/game mode, intensity context — features we're building with our pilot partners.

Every athlete's weekly PDF goes home branded with your academy's logo. Parents see progress every Sunday, not just at the end of the season. Families cancel less when they can see the work.
Every academy in SoCal promises "personalized training." None of them ship week-over-week data to parents. Slingshot gives your program the only sentence that closes the sale: "You'll see exactly what your kid improved on, every week."
No $3,600 annual commitments. No 10-player minimums. No sports science consultant required. We're running 5 pilot partnerships with SoCal academies this summer at breakeven cost — $75 per unit, one-time.
Five college students who came up through athletics — a varsity football captain, a varsity golfer, and three operators who lived in dojos and gyms instead of on team rosters. We know what a $1,200/month parent expects, and we know what a trainer running 15 kids a day actually has time for. No venture-capital bloat. No enterprise nonsense.
Our algorithm fuses sprint intensity, jump events, and movement zones into one number between 0 and 100. Compare it across players, across sessions, across seasons — the receipt parents have been asking for.
Approximate intensity zone tracking from the upper-arm sensor. Directional signal, not clinical measurement — paired with Session Load to translate raw effort into something a parent at 9pm understands at a glance.
We're five college students. We're not optimizing for revenue this summer — we're optimizing for getting it right. Hardware ships at breakeven. Our return is your feedback, your reference, and the chance to build the version of this product that should have existed five years ago.
One marquee program. 10-week summer pilot. All hardware, software, and support included. In exchange: weekly feedback, two warm intros, and reference rights when we ship.
Hardware at breakeven. No subscription. No annual contract. 10-week summer pilot, all features included. We make $0 on the 2026 pilot — that's the point.
Catapult One locks you in for 2 years at $3,600 before you see your first data. We're a 10-week pilot. You try us, you tell us what's broken, you walk if it doesn't work.
We're five college students building the wearable that should have existed five years ago. This is the unfiltered story — the hardware that didn't work, the trainers who told us we were wrong, the pilots that taught us what the data should actually look like.
We're running 5 design partner pilots in Summer 2026 in Los Angeles. Apply for a pilot slot, or join the waitlist for Fall 2026. Basketball trainers and coaches only.
