Why we build it
Every hour of real practice has needed a second person — to rebound, to watch, to tell you the truth. We are engineers who play, and we are replacing that person with a machine.
Before writing a line of code, we stood on a court with a stopwatch. Out of one hour of solo shooting, roughly half was walking after the ball. That's the entire company, in one measurement.

The Vision
Coaching is rationed by geography and money. The players who improve fastest have a gym, a coach and someone to pass them the ball — not the most desire. We build the part of that you can carry.
The Mission
One number decides everything we build: honest repetitions per hour. These three rules follow from it.
01
A training tool is judged by one number: quality repetitions per hour. Every feature must raise it. Everything else — however clever — gets deleted.
02
The camera doesn't flatter you, and neither does this website. Release angle, arc, consistency — shown exactly as measured. Improvement starts from the truth.
03
The feeder is a cartridge you can swap in seconds; wear parts unbolt instead of unglue. A machine you can fix is a machine you keep.
The Bench
This is a robotics company that builds for basketball. The people here come out of drone flight control, electric mobility, on-device perception and university robotics labs, and they brought their standards with them: a drive that repeats to the millimetre, perception with no cloud in the loop, a stop path measured in milliseconds.
Founder · Computer Engineering
Timed his own practice hour and found most of it went to chasing the ball rather than shooting. Built the first arc-tracking prototype on a borrowed depth camera that month. Owns the shot model and the product roadmap.
Drive & Structures
Drone propulsion and electric mobility before this. Owns the twin-roller feed: the spin-rate servo loop, the torque ripple that used to put a wobble on the ball, and the folding chassis that keeps the whole machine at five kilograms. Holds the feed to a repeatability figure, not a tolerance band.
Perception & AI
Runs the sensing stack: the solid-state LiDAR return path, its calibration against the 4K/120 stereo pair, and the fusion that turns both into a pose. Release angle, arc and joint tracking are all solved on the machine. No court has Wi-Fi, and no session leaves the unit.
Controls & Safety
Real-time control and the whole interlock chain around it — motion planning, the watchdog, and the stop itself. The machine shares a floor with people who are not watching it, so the stop path is wired rather than scheduled: it holds even if the software is gone.
Sport Science
Former players and a strength coach with veto authority over every metric the product reports. They decide what counts as a rep, what counts as a clean release, and what a session summary is allowed to claim. A number that does not change your next session does not ship.
Every one of us plays. That is not a brand value — it is why the company exists.
