I quit my VP role to build the coach I wish I had.
Two years ago, my cousin asked if I wanted to learn tennis. Growing up watching prime Federer and Nadal with my dad, competing in racket sports through school — something about being on court just clicked. I was hooked.
Three walls every solo player hits
But as I got serious about improving, I kept hitting the same three walls:
- I couldn't afford a coach 3x a week. Private lessons add up fast. Most of my practice was solo — hitting against a wall, feeding balls from a machine — with no one to tell me what I was doing wrong.
- I was too shy to ask questions. In group lessons, I'd nod along even when I didn't understand the correction. I wanted to rewatch, slow down, and process feedback on my own terms.
- My coach wasn't available at 11pm When I was replaying my session in my head, wondering if my follow-through was too low.
These aren't unique problems. Talk to any recreational player who practices solo and you'll hear the same story — the desire to improve is there, but the feedback loop is missing.
What if your phone could see what a coach sees?
I have a background in computer science and data science. The moment neural networks clicked for me in grad school — the idea that a machine could look at a video and understand movement the way a human does — I knew this was where I wanted to be.
I spent months studying how coaches actually diagnose strokes. Not the generic YouTube advice, but the biomechanical details: how hip-shoulder separation creates rotational power, how the kinetic chain transfers energy from ground to racket, how contact spacing determines whether you're cramped or extending properly. The kind of analysis that used to require a lab and reflective markers.
TorqAI uses Apple Vision to track 17 body joints at 30 frames per second — entirely on your phone, no special equipment. It diagnoses your forehand, backhand, serve, volley, slice, and overhead with the same biomechanical lens a sports scientist would use, then translates that into coaching you can actually act on.
More than analysis — a training partner
But diagnosis alone doesn't help you improve. You need a plan. That's why TorqAI builds a personalized weekly training program based on what it finds in your strokes — on-court drills for your weakest areas, off-court exercises for the gaps between sessions, and progressive difficulty that adapts as you get better. It's not just telling you what's happening; it's giving you a structured path to improve.
The Form Lab tracks your stroke ratings and biomechanical data over time, so you can see whether your practice is actually working. No more guessing. No more hoping. Just data.
TorqAI is what I wish I had from day one: a coach that watches every swing, never judges your questions, and is there whenever you are. — From one tennis nerd to another, Leona
