From 6,307 players to the one worth signing.

We are a consultancy specializing in football data analysis. We help clubs in Poland and abroad assess transfer risks, identify players who best match expected profile and football level, and make data-driven decisions.

  
  1. All positions
  2. Midfielders
  3. 24 or younger
  4. No loans
  5. Value up to €1.5m
  6. Ekstraklasa top 25%
  7. Shortlist
Each point is a real outfield player from 2025/26 (1000+ minutes), positioned by league strength and estimated individual level. Data anonymised.

Services

We do not sell access to a data platform. Instead, we use stats and observations to answer the club's specific questions, allowing to avoid the escalating costs of excessively expanding in-house analysis and scouting departments.

Transfer risk
assessment

We estimate how a player's metrics will translate to the target league, accounting for the gap in league strength, age curve, availability and role fit. The result is a range, and we name the sources of uncertainty explicitly.

You receiveA two-page report with the projected level stated as a range.

Scouting
and recruitment

We build shortlists against a defined role profile, budget and age band. We apply a minutes threshold and exclude loanees, so rankings are not driven by small, noisy samples.

You receiveA ranked shortlist with a quantitative rationale for each name.

Cross-league market intelligence

We identify players whose level, after cross-league adjustment, would hold in another competition. The same method supports pricing a player sold to a stronger league.

You receiveA market report on a chosen league, filtered to your level.

Squad
audit

We benchmark the squad against the league, position by position: who actually drives performance, where the gaps are and which expiring contracts need a successor now.

You receiveA squad map, priority gaps and successor candidates.

Performance and
opposition analysis

We analyse the playing patterns of your team and the next opponent: strengths to neutralise and weaknesses to exploit, in a form the staff can read in twenty minutes.

You receiveA match-week brief for the coaching staff.

Football data
engineering

We clean, standardise and maintain data from multiple sources and providers, so analysts, scouts and the sporting director work from one consistent dataset rather than scattered spreadsheets.

You receiveA maintained dataset and the reports built on it.

What a transfer assessment looks like

One player, three target leagues. Stats from his current league are measurements. His level in another league is an estimate, so we report it as a range. Switching the target league shows how the projection shifts and the uncertainty widens.

  • Level: percentile among midfielders of the target league
  • Adaptation risk: league gap, age and role
  • Data limitations: stated in one sentence

Our process, step by step

Going from first call to final report usually takes days, not weeks. Urgent requests during a transfer window take priority.

  1. Brief

    We define the research question, the budget and the role profile. The precision of the question determines the choice of method and data.

  2. Data

    We work with event data normalised per 90 minutes. We apply a minutes threshold and adjust for team strength: a dominant side inflates attacking metrics, a weaker one deflates them.

  3. Model

    We estimate league strength from independent team ratings and calibrate our cross-league conversion on data from 26 leagues. Small samples are shrunk towards the league mean. Every projection carries an uncertainty range.

  4. Decision

    A short report a sporting director can read in two minutes: findings, risks and what still needs to be verified live and on video.

Our working standards

Every claim has a number

We don't write that a player is “good in attacking duels”. We report the value per 90 minutes, the success rate and the percentile among players in the same position.

7.1 defensive duels per 90 minutes, 64% won: better than 85% of centre-backs in his league.

We separate measurement from estimation

A percentile within the player's own league is a measurement. His level in another league and his development projection are estimates, always reported as ranges.

Projected level in Ekstraklasa: 64th to 78th percentile.

Limitations stated plainly

Small sample, dual role, a season cut short by an injury: we say so in one sentence at the top of the report, not in the fine print.

Based on 1140 minutes. Defensive metrics should be read with caution.

Every number can be checked

Each report states the season, the minutes behind every figure and the method that produced it. Anyone on the club's staff can trace a conclusion back to the source data.

Data: 2025/26 season, 31 matches, 2410 minutes.

26 leagues, 17 countries, 432 clubs and 6,851 players in the database.

The database holds players with at least 1000 minutes in a season, assessed in 18 role profiles. Season 2025/26; Norway uses the 2025 calendar season and Sweden the ongoing 2026 season. For Ekstraklasa we also hold the full season with no minutes threshold (545 players) for team analysis, plus current 2026/27 data for Ekstraklasa, 1 liga and II liga (1250 players after 9–10 games).
