Stop Guessing.
Start Simulating.
FitSim tells you exactly how a player will perform in your tactical system — before the bid, before the medical, before the contract. Built by football people. Verified by AI.
Transfer Failure Is Costing Clubs Millions
Traditional scouting measures what a player has done in someone else’s system. It tells you about their past, not their future in your setup. We built the science clubs don’t have.
Clubs across Europe lose hundreds of millions annually on players who fail to adapt to new systems.
of transfers underperform within 18 months
Standard analytics compare players on raw metrics — they don’t account for tactical system compatibility.
Transfer windows move fast. Without simulation, clubs make multi-million decisions in days.
The best signings are often players performing poorly in the wrong system — who will thrive in yours.
Multi-System Simulation.
Patent Pending.
FitSim’s AI engine doesn’t compare past stats. It simulates future performance — projecting how each player will behave inside the specific tactical demands of your club.
We model your formation, pressing triggers, defensive shape, build-up patterns, and transition behaviour — creating a unique fingerprint of your system.
Our patent-pending engine runs thousands of performance projections per player — stress-testing them across your tactical demands and producing a ranked compatibility score.
Receive a full compatibility report per player: fit score, risk assessment, projected performance range, positional variance analysis, and recommended use cases.
FitSim analyses players across all major European leagues and selected global markets — surfacing players that traditional scouting would never surface.
As your system evolves through the season, FitSim updates compatibility scores in real-time — keeping your shortlist accurate to your current tactical identity.
Every club’s tactical fingerprint is protected. Your system data, shortlists, and simulation results are fully encrypted and exclusive to your organisation.
Retrospective Validation Study
We applied FitSim’s methodology retrospectively to one of football’s most celebrated transfers — to test whether our simulation would have identified the player as a system fit before the signing.
A world-class centre-back who became one of the most dominant defenders of his generation was identified years before his breakthrough by a scout whose instinct said he would thrive in a high-pressing, ball-playing system.
FitSim applied its multi-system simulation retrospectively to that player’s data at the time of scouting. Result: a system compatibility score placing him in the top 3% of available centre-backs for a high-press, possession-based 4-3-3 — the exact system he went on to dominate.
Our simulation confirmed what elite instinct identified. FitSim exists to give every club access to that level of insight.

From Shortlist to Signed in Four Steps
FitSim integrates into your existing scouting workflow — adding simulation intelligence that protects your investment and surfaces hidden value.
Your coaching staff brief FitSim on your tactical identity — formation, pressing model, build-up phases, defensive structure, and transition priorities.
Submit your transfer target list. FitSim can also generate a target list matched to your system from the global database.
FitSim runs multi-system simulation across all targets — generating compatibility scores, risk profiles, and projected performance ranges within 24–48 hours.
Receive a ranked shortlist with full compatibility reports. Present to your board, head of recruitment, or ownership with data-backed confidence.
The Signing
Is Just
The Start.
Most analytics platforms stop when the deal is done. TSi — FitSim’s Transfer Success Index — begins the moment your new signing walks through the door. It tracks every player against their pre-transfer simulation, giving you a live, financial ROI score on every transfer decision your club has made.
Every signing gets a live performance tracking dashboard — comparing FitSim’s pre-transfer simulation prediction against real match data, week by week, as the season unfolds.
TSi calculates a real-time financial return estimate for every transfer — tracking estimated current market value against purchase price to give your board a clear picture of squad capital.
As your tactical system evolves through the season, TSi recalibrates each player’s compatibility score — flagging early divergence from the simulation before it becomes a problem.
In my career as a player and in football administration, I've seen too many transfers fail not because of lack of talent — but because of lack of fit. FitSim is solving the problem that football has never had the tools to address before.
