The game is decided in the half-second before the ball moves. ARena is the platform built to train that half-second — and, for the first time, measure it.
Physical tracking is maxed out. When output is automatic, it stops being an edge and becomes the price of entry.
Elite budgets are shifting hard toward real-time decision-making — where the remaining margin actually lives.
Sub-frame XR latency and on-device AI can finally process instinct at game speed, without the lag that killed every earlier attempt.
No simulator room. No joystick. A real floor, a real ball, a real body — and a defense that arrives the instant the coach calls it.
From a sideline tablet: action, coverage, pressure, time. No scripting, no engineer in the gym.
Defenders appear on the real hardwood, reading and closing at game speed — never identical twice, so it can't be memorised.
Footwork, pivots, the pass. The rep stays physical; only the pressure is generated.
Not a clip to review next week — a score on the read itself, while the player is still standing where it happened.
A drill hour gives a handful of genuine reads. ARena delivers them back to back, each one scored.
Underneath the basketball sits a general loop: simulate a situation, analyse how a human reads it, return a score inside the rhythm of practice, and shape the next rep around the answer. Four layers, exposed as an SDK.
Projects the scenario onto the physical court — action, coverage, pressure, time. Parametric, so difficulty moves continuously.
Tracks movement, orientation and reaction time on-device. The play becomes a structured graph of what was seen, and when.
Turns raw action into one number a coach can act on — calibrated against expert coaches, not invented by the model alone.
The system learns the player over time, so pressure keeps landing on the weakness — not the comfort zone.
One objective number for court vision and reaction — built with sports researchers, performance experts and computer-vision engineers, and calibrated against real coaching judgment, not invented by the model alone.
Under the hood it draws on eye-tracking, motion tracking and computer vision — the class of technology elite performance labs use, running live on a normal court.
None of the four layers is impossible alone. Holding all of them together at game speed, on a real floor, is the actual problem.
Feedback after the next rep has started is a report, not coaching. The read must be captured and returned inside the rhythm of practice.
Speed you can time with a stopwatch. Quality needs a reference — expert coaches judging the same reps, kept only where they agree.
The ball, floor and body are real. Holding a generated defense in exact registration with all three is where immersive training usually breaks.
We aren't betting on a device. The engine moves as hardware moves. What stays constant is the decision layer.
Basketball is where we prove it: the densest decision sport, the fastest to adopt, the hardest to fake. But nothing in the engine is basketball. Swap the scenario layer and the same loop reads a midfielder, a quarterback, or a unit clearing a room.
Design partners and a working baseline, built hand-in-hand with the coaches who use it every day.
Rolling out across coaches, academies and programs beyond the first design partners.
The same engine scales into soccer, football and tactical training verticals.
Deployable in a normal training facility, run by the staff already standing in it.
Develop reads in young players before habits set, with progress you can show a director or a parent.
Give staff an objective view of decision-making that survives an argument in the film room.
Add high-volume decision reps inside strict practice-hour limits.
Apply one standard of decision quality across programs and age groups.
Single-floor deployment for personal coaches, high schools and small programs.
Multi-player rosters, session history and staff accounts.
Custom scoring philosophy, multi-site deployment and integration support.
We're onboarding a small group of academies, clubs and performance centres as design partners — early access included.
