What is Overit Finland?

Overit Finland is the Finnish company directory — a platform that brings together information on Finnish companies, verification, change monitoring and developer APIs in one product. Check who you do business with in seconds.

Where does the data come from?

From Finnish public registers: the Commercial Register, YTJ, the Trade Register and the EU VIES system for VAT number validation.

How do verification and the Overit score work?

Overit aggregates register data, filing history and monitoring signals into a single Overit score (0–100) plus a separate risk level. Both update automatically as new data arrives.

How often is company data updated?

Core register data refreshes daily; watched companies get near-real-time updates whenever a tracked event — such as a board or status change — is detected.

What does Radar track?

Radar tracks board changes, new annual reports, company status changes and registered-address changes for every watched company — alerts arrive in the Overit App dashboard or via webhook.

Does Overit offer APIs for developers?

Yes. The Overit API is a REST interface with JSON responses covering company lookups, verification and report data — integrate it straight into your own product or internal tools.

Know who you are dealing with

Overit verifies Finnish 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 Finnish registers.

Board checks

See who stands behind a company — board members and shareholders straight from the Business 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.
