Slingshot is a wearable sensor pod for basketball. Session Load Score, sprint counts, jump metrics, and intensity zones: the analytics that pro systems lock behind team contracts and player minimums. We're building it for the trainers those platforms left out, and the first units go out in our summer pilot.
5 design partner slots for Summer 2026. Fall 2026 waitlist open.
Composite of sprint intensity, jump events, and movement zones. Intensity figures are directional, not clinical.
Catapult Vector and STATSports serve pro and D1 programs. Catapult One reaches youth and high school, but on a ten-player minimum and a two-year contract, with software built for sports scientists. None of them were ever an option for a basketball trainer, an AAU program, or a high school coach.
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 basketball programs Catapult was never going to serve.
The Session Load Score tells you how hard each athlete worked, built from sprint intensity, jump data, and movement zones, with heart rate shown alongside. Here is what v1 does. We are building and proving it in the summer pilot.
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.
Every athlete, every session, on one screen. See who needs attention at a glance. Flag who's pulling back. Spot trends before parents ask. The tool you'll want at 5pm after a fifteen-kid day.
The pod streams to the coach dashboard over Bluetooth during the session. See who's spiking and who's coasting in real time, from a laptop on the sideline. This is the core of what the summer pilot proves on the real board.
A clean weekly summary you can send home. Session Load trend, standout sessions, a coach's note.
Every jump tracked. Vertical measured session by session. The number recruits and parents both watch.
Every explosive burst logged automatically. Tuned for basketball's 5-to-10 yard bursts, not soccer-style distance. Know which players are pushing and which ones are coasting.
Green, yellow, red. A simple read on how each player spent the session, from the max-intensity grinders to the ones who barely broke a sweat.
Export every metric, every session, every athlete to CSV in one click. Your data is yours. No lock-in, no paywall.
A cheaper, smaller board. Accounts and cloud sync. Shot detection, leaderboards, and game modes. v2 is in design.

Every athlete's weekly report goes home. Parents see progress every week, 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 send week-over-week data home. Slingshot lets you tell a parent: "You'll see exactly what your kid improved on, every week."
No $3,600 commitments. No ten-player minimums. No sports science consultant required. We're running a handful of pilot partnerships with SoCal academies this summer, priced below our cost on purpose.
We're three founders putting our own savings into this, not a venture-backed team building from the outside. We know what a trainer running fifteen kids a day actually has time for, because we've been in those gyms. No enterprise bloat.
Slingshot fuses sprint intensity, jump events, and movement zones into one number from 0 to 100. Track it session over session, and see at a glance who needs attention.
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 understands at a glance.
We're three founders funding this out of our own savings. We're not trying to make money on the summer pilot. We're trying to get it right. The pilot is priced below what it costs us to build, because what we want back is your feedback and the chance to build the version that should exist.
One marquee program. A ten-week summer pilot. All hardware, software, and support included. In exchange: weekly feedback, two warm intros, and reference rights when we ship.
$75 per unit, one-time. No subscription. No annual contract. A ten-week summer pilot, all features included. We're not making money on this. That's the point.
Catapult One needs a ten-player minimum on a two-year contract, roughly $3,600 in commitment before you see your first session. We're a ten-week pilot. You try us, you tell us what's broken, you walk if it doesn't work.
We're three founders building in the open. The decisions, the dead ends, and what the data actually says.
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.
