Know who you are dealing with
Overit verifies Luxembourg companies, partners and suppliers against official data and continuous monitoring, so you can act with confidence.
Company verification
Confirm in seconds that a company exists, is active and matches the official Luxembourg registers.
Board checks
See who stands behind a company — board members and shareholders straight from the Trade and Companies Register.
Business partner screening
Screen prospective partners and clients before signing a contract or extending credit.
Supplier checks
Verify the legality, financial stability and operational risk of suppliers in your supply chain.
Overit score
A 0–100 score of how complete and well-sourced a company profile is: filings, board, contacts. Not a credit rating — risk level is a separate figure.
Risk radar
Continuous monitoring flags emerging risks before they become problems.
Example Overit score
Based on register data, annual reports and continuous monitoring — sample profile.
Overit API for developers
Integrate Luxembourg company data, verification and monitoring straight into your product through a clean, JSON REST API.
