Overit Finland is an independent Finnish company directory that brings information from public registers together on one platform. It helps individuals and organizations check who they are dealing with by searching for businesses by name, Business ID or VAT number. The directory includes company profiles, financial statements, ownership and board information, and other available registry details.

Its services support company verification, partner and customer screening, and supplier checks. Users can review registration status, assess profile completeness through Overit scores, and view a separate risk indicator based on published financial statements. The monitoring service, Tutka, tracks selected companies and notifies users of changes such as new financial statements or updates to registry information. Overit also provides company search, change histories, relationship information and bulk export options, depending on the plan.

For developers and platforms, Overit offers a REST API with JSON responses, bulk-search and verification endpoints, and financial statement data. Webhooks are offered for notifications about company changes.
