AI opponent intelligence · ATP & WTA
The stats tell you they choked. We tell you how to make them.
Double Fault uses AI to read a match from a perspective no human can — the psychological tells that decide it, in real time.
The problem
≈ 3.8 points separate the #1 from the #100. Coaches obsess over technique and shot patterns. The thing that actually decides tight matches — when an opponent tightens up and double faults — has never been measurable. Until now.
The product
One opponent profile, built from broadcast footage, scored and ready before you hit the practice court.
Every opponent reduced to one honest number — how readable they are and how fast they come apart. Track it match to match, surface to surface.
"The Metronome" · current read
Error zone · BH · 2nd serve
No wearables, no cameras to install, no cooperation from anyone. If they've played on TV, we can read them.
Profiles update as the season runs, so the read you walk on with is the read from last week — not last year.

Opponent 0148 · "The Metronome"
Highly readable under pressure. Composure holds on serve early, then degrades sharply when chasing — especially in the heat and past the eighth shot.
Win % by surface
Read
Strongest on hard, where the serve patterns hold. Grass exposes the slow first step and the wide-slider tell — the surface to attack the toss.
Serve placement · 2nd serve
Every serve from the sample, mapped. The faults isolate in orange — a cluster wide on the backhand under pressure. That's where the return stands.
How it works
Five years of ATP & WTA — 250/500/1000, Challenger, Futures.
Pose, ball & serve tracking and affect models read every frame.
Detect, weigh and file each cue into a proprietary taxonomy.
A dossier, a pressure map and one Double Fault Score, ready to brief.
The difference
Every tool on your bench measures the ball or the scoreline. Here's the gap they all leave — and the one thing we do instead.
Hawk-Eye · ball tracking
Speed, spin, placement, line calls — pinpoint truth about every shot you both hit.
Truth about the ball. Nothing about the person hitting it.
ATP · Infosys · TennisIQ
Break points, conversion, rally length — even "under-pressure" ratings.
Outcomes, after the fact. They show that a player faltered — never why, or that it was coming.
You · the tapes
Feel, instinct, the context only a coach who knows the player has.
But no one holds 300 matches in their head — the pattern only lives in the aggregate.
Double Fault
Why you can't just watch the tapes yourself
The tells that matter don't exist inside any single match — only in the pattern across all of them.
No brain stores every 30–40 second serve and every shoulder drop after a let. Ours keeps all of it.
The read compounds as the season runs and new footage lands — it never forgets and never tires.

Questions
Yes. Double Fault is built on licensed ATP & WTA footage under a tour partnership, and it does exactly what coaches and players already do — scout an opponent before a match. We just do it with AI, from public broadcast, at a depth no human eye can match.
Because those measure the ball and the scoreline — speed, placement, break-point conversion, even "pressure" ratings. They're outcomes: they tell you a player faltered, never why or that it was coming. Double Fault reads the player instead — the body language, the composure that holds or breaks, and the tactic that gives it away — across hundreds of matches at once, which no tracking system or stat sheet exposes.
In a single match, a coach's eye is worth a lot — and we never replace it. But the tells that matter live in the aggregate, across hundreds of matches, and no human retains every 30–40 second serve or every shoulder drop after a let. The AI watches all of it, remembers all of it, and never tires — then hands your coach a read to take into the room.
No. Double Fault is pre-match scouting only. There is no live coaching signal during play — the dossier is something you study the night before, like any other prep.
Five years of official broadcast footage from both tours. No wearables, no biometric devices, no private data — if a player has competed on television, we can build their profile.
Every tell carries a confidence and a measured effect size, and you can see the evidence behind it — the matches, the moments, the numbers. It's a scouting tool that shows its work, not a black box.
Players, coaches, analysts, agents, academies and federations — anyone preparing for an opponent. Plans scale from a single Futures pro to a whole national squad.
Full access for three months, for any player, with no card required. You get complete opponent profiles, Double Fault Scores and pressure maps — enough to take into a real event and feel the difference.
