Overround

Overround builds data and research products for sports.

What we do

We collect and model league data, then build software that helps people understand what happened in a game and what is likely to happen next. The work is statistical: sourcing records carefully, keeping them consistent over time, and documenting how every derived number was produced.

Data

Collection, normalization, and historical archives for the leagues we cover.

Research

Statistical models and derived metrics, documented so a user can trace how a figure was reached.

Products

Subscription software built for a defined audience, run and supported in-house.

Products

On the name

In sports markets, the overround is the margin built into a set of prices. The implied probabilities across every outcome sum to more than 100%.

It’s the gap between what a number says and what’s actually true. Studying that gap is what we do.
