What is Topograph?

Topograph turns the complexity of European public registers into a standardized, developer-friendly API. We help you build fast KYB (Know Your Business) onboarding flows and rigorous verification processes without dealing with the fragmented landscape of European company data.

KYB Onboarding Guide

Best practices for building onboarding flows with high conversion rates.

Register Complexity

The Onboarding Flow

We provide specialized endpoints for each step of a modern KYB onboarding flow—from the first search to final document verification. Let users find their company instantly.

​
4. Monitor

Keep your data up to date.

Monitoring

​
Key Capabilities

Beyond the core onboarding flow, Topograph solves the hard problems of international company data:

Data Standardization

We map local specifics to international standards: ISO 20275 for legal forms, ISO 5009 for roles, and ISIC/NACE for activity codes.

Reliability & Fallbacks

Public registers are unreliable. We handle retries, timeouts, and failovers to ensure your API calls succeed.

Financial Data
