Build models you can trust.

Tendency is a research-grade NFL + CFB analytics OS: clean data, versioned metrics, and reproducible backtests—without the hype.

Reproducible backtests

Run the same test twice. Get the same answer. Every time. Versioned feature sets ensure your results are always reproducible.

Attribution-grade metrics

Separate QB signal from line signal. Track tendencies that actually move outcomes. Know what's driving the numbers.

Warehouse + exports

Query, filter, and export datasets that are ready for modeling. CSV or Parquet, your choice.

Trust by design

Every metric includes definitions, sources, and timing rules.

If it wasn't knowable then, it isn't used. That's the promise.

How it works

1

Start with the Slate

See what matters this week. Game cards show QB-VA delta, OL signals, pace indicators—the signals that move outcomes, not noise.

2

Drill into any game

See the full matchup DNA: attribution metrics, coaching tendencies, market movement. Every metric shows its definition and data lineage.

3

Test your thesis

Run backtests that actually mean something. We enforce available_at timestamps so you can't accidentally use future information.

4

Export and build

Take clean datasets to your own models. We provide the research-grade data; you provide the edge.
