Analytics that prove you can actually pick
Anyone can win on a hot streak. Windfall goes past win/loss and measures whether you're genuinely good, with the same numbers sharp bettors live by.
Flagship metric
Closing Line Value
The one number sharp bettors swear by. Every time you make a pick, we compare the odds you took to where the line closed. Consistently getting a better number than the close is the clearest sign your reads are ahead of the market, and we show you exactly how often you do it, across every pick you've ever made.
Performance breakdowns
Win rate and ROI sliced by sport, bet type, and favorites vs. underdogs. See the spots where you're genuinely sharp, and the ones quietly costing you points.
Skill vs. luck
We turn every pick's odds into a win probability and compare what should have happened to what actually did, so you know whether you're truly good or just running hot.
Bankroll discipline
Track how consistently you size your picks and your biggest drawdowns. The habits that separate disciplined players from the ones who press too hard.
Leak detection
Windfall automatically surfaces the bet types and situations where you lose the most, ranked worst-first, so you can plug the holes in your game.
Early-bet edge
Windfall rewards calling your shots early. See how much of an edge your early picks capture versus waiting, and whether timing is one of your strengths.
Percentile ranking
See where your skill metrics stack up against your league and the entire Windfall player base. Proof, in a number, that you're better than the field.
