The Problem

Nobody Cross-Checks Your Data.

Until now.

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

One API. Every Provider. Cross-Validated Data.

Swap providers without changing a line of code.

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. Teams that build this in-house spend $30-75K per integration and $30-60K/year maintaining mappings. SportsStack normalizes every provider into one schema, one SDK, one set of IDs.

Cross-Provider Validation

Expensive to build in-house.

Checking one provider's data against another in real time is something no individual provider offers and no internal team has built. SportsStack is the only platform that cross-validates stats, scores, and odds across providers before settlement.
