The Problem

Data Providers Make Mistakes.

We ensure your customers never know about it.

One provider can't check itself

When stats or odds are wrong, your users see it before you do.

Manual QA can't keep up

Thousands of live data points per minute across every event.

Mistakes are costly

Sharps pick off stale lines. Misgrades mean paying out both sides.

How It Works

Conflicting Feeds In. One Trusted Answer Out.

Cross-check every stat before it becomes a misgrade, bad market, or incorrect score.

WHAT YOUR ENGINEERS SHOULD NOT BE BUILDING

Build What Makes You Different.

Not what makes you the same as everyone else.

Entity Resolution

Solved problem. Hundreds of edge cases.

Mapping player IDs across Sportradar, Genius, and your other feeds is real engineering work with real edge cases: name transliterations, mid-season trades, merged/split events. We maintain 500+ edge case rules so your team doesn't have to.

Provider Normalization

Repetitive work. Compounds every year.

Every new provider means a new schema, new quirks, new failure modes. Built in-house, each one is months of integration work plus a mapping table someone has to own forever. SportsStack normalizes every provider into one schema, one SDK, one set of IDs.

Cross-Provider Validation

Expensive to build in-house.

No single provider can check itself, and building real-time reconciliation across feeds is a project in its own right. SportsStack cross-validates stats, scores, and odds across providers before settlement, so bad values never reach your customers.
