Revenue concentration

The ten largest entities generate three quarters of the published top 30's revenue.

The top five account for 54.8%, while the top ten account for 75.0% of the published sample's €599.6 million in revenue. This describes the structure of the ranking, not an official market share for the whole legal-services market.

Methodology

How was the top-30 law-firm ranking built?

The ranking is a static snapshot dated August 29, 2026. It combines the DM Faster company registry, official PRH identifiers, the Finnish Bar Association's law-firm naming rule, and company-level public financial observations.

  1. 1. Defining law firms

    The candidate population contains 169 active Finnish entities whose name, main industry, or reviewed activity indicated a law firm.

  2. 2. PRH identity verification

    Every published row was matched to a current official name and Business ID in PRH Open Data. Foreign branches, ended entities, and duplicate identifiers were removed.

  3. 3. Financial observation

    Each entity received its latest trusted legal-entity revenue observation from DM Faster company data. Fiscal year and personnel remain visible row by row.

  4. 4. Quality control and ranking

    Patent agents, generic legal services, and broad tax or transaction advisers were separated from law firms. The remaining entities were sorted by revenue and the largest 30 were published.

Limitations you should read

  • This is a reviewed market slice from DM Faster company data, not an official Finnish Bar Association or Statistics Finland market census.
  • The ranking covers Finnish legal entities. International group revenue and foreign parent-company figures are excluded.
  • Patent and trademark agencies, generic legal-service providers, and broad tax or transaction-advisory firms are excluded unless the legal entity is specifically a law firm.
  • Separate legal entities belonging to the same brand or group may appear as separate rows. Roschier Asianajotoimisto Oy and Roschier Brands Asianajotoimisto Oy are therefore ranked separately.
  • The latest comparable revenue observations cover fiscal years 2024 and 2025. The year is shown row by row and the figures should not be interpreted as same-year market shares.
  • Two entities have no available personnel observation in the source used. The employee total covers 28 entities and does not represent global network headcount.
  • Revenue measures legal-entity size, not legal quality, profitability, client satisfaction, or suitability for a particular matter.
  • Public financial data changes. Rankings can move after a new filing, merger, demerger, or source correction.
