I started playing pickleball in 2022. Within six months, I had tennis elbow so severe I couldn't hold a coffee cup. I'm an engineer and an entrepreneur — my first instinct was to understand the biomechanics behind what happened. What I found shocked me.
The numbers are staggering.
Pickleball injuries aren't just inconvenient — they're expensive, they destroy retention, and they create real liability for the facilities hosting the games. Tennis elbow, rotator cuff tears, ACL injuries, herniated discs, plantar fasciitis — we tracked 13 distinct injury vectors that account for the vast majority of pickleball injuries.
And yet, not a single product on the market was designed to prevent them.
The existing solutions solve the wrong problem.
SwingVision, PBVision, Wingfield — they're all excellent at what they do. But they track the ball, not the body. Shot speed, spin rate, score tracking. That's useful for competitive analysis, but it does absolutely nothing for injury prevention.
You can't prevent injuries by watching the ball. You have to watch the body — in three dimensions, at 30 frames per second, tracking every joint, every angle, every force.
That's the fundamental insight behind Aeterna. We don't track shots. We build a complete 3D Digital Twin of each player — a real-time biomechanical model that tracks 34 body joints in true X, Y, Z space.
Why 3D matters more than you think.
Here's something most people don't realize: a 2D camera system literally cannot detect lateral forces. If a player's knee is rotating inward during a lunge — the #1 predictor of ACL tears — a 2D system sees nothing unusual. The movement happens in the Z-axis, which is invisible to a flat image.
Our 3D engine sees everything. Elbow pronation angles during a backhand. Spinal compression at L4-L5 during a hard serve. Ankle inversion during lateral movement. These are the forces that cause real injuries, and they can only be measured in three dimensions.
Protected by 2 Issued Patents
We didn't build Aeterna by stringing together AI APIs. Our dual-engine biomechanics system — combining proprietary 3D skeletal tracking with real-time injury prediction — is protected by two issued patents. This technology was built from the ground up by our engineering team, running on trusted infrastructure from Google Cloud, NVIDIA, AWS, and Azure.
What this means for facilities.
If you run a pickleball facility, here's what keeps me up at night on your behalf: every one of your competitors is offering the exact same experience. Same courts, same nets, same lights. When a new facility opens down the road, your members have zero reason to stay.
Aeterna changes that equation. When you can offer your members personalized injury prevention powered by 3D Digital Twin technology — with Google, NVIDIA, AWS, and Azure logos on your front door — you become the only facility in your market that can guarantee the safest play. That's not just differentiation. That's a moat.
Add in the revenue impact — coaching upsells, equipment recommendations, retention saves, liability reduction — and the ROI becomes undeniable. We've seen facilities generate measurable revenue within 12 hours of activation.
What comes next.
We're just getting started. The same biomechanics engine that protects pickleball players applies to tennis, padel, badminton, squash, and any racquet sport. Our roadmap includes recovery tracking, personalized warm-up protocols, and integration with wearable sensors for even deeper analysis.
But the mission hasn't changed since day one: use technology to keep people playing the sports they love, longer and safer.
If you run a facility and want to see what this looks like in practice, I'd love to show you. Reach out at team@idur.ai or visit our homepage to book a demo.
