The Data Engine for
Your SaaS.
Don't waste engineering cycles building scrapers. Embed the UK's most comprehensive corporate data graph directly into your product. White-labeled, invisible, and ready to ship.
ZINT API
Infrastructure Layer
You build the UX.
We'll handle the chaos.
Your customers demand 'smart' featuresāauto-enrichment, risk flags, and market insights. But maintaining a pipeline of 5 million companies across 20+ disparate registries is a full-time job for an entire data team.
Stop fighting with Companies House rate limits and broken HTML scrapers. Zint provides a clean, standardized infrastructure layer that lets you deploy high-value data features in days, not quarters.
