Methodology
How was the Lahti top 30 built?
DM Faster's Finland company registry is built from PRH company and location data, then enriched with financial, personnel, technology, and sales signals. For this report, Lahti's current municipal population was verified on August 31, 2026 and every published revenue row was checked against DM Faster financial data.
1. Registry foundation
DM Faster's PRH-backed location data identified 12,148 Lahti observations.
2. Company normalization
Current address under municipality code 398, active trade-register status, legal name, and Business ID were normalized. This produced 7,976 active entities.
3. Financial enrichment
DM Faster's financial enrichment connected an exact 2024 or 2025 revenue observation to 640 companies.
4. Normalization and ranking
Office and service labels were replaced by current legal names. Entities were sorted by revenue and the largest 30 were published with their evidence.
How to read the figures
- DM Faster's PRH-backed registry covers 7,976 active legal entities with a current visiting or postal address under Lahti municipality code 398.
- The revenue ranking contains the 640 companies that DM Faster has enriched with an exact 2024 or 2025 revenue observation.
- The ranking covers legal entities. Group figures, brand sales, local-establishment sales, and revenue from other entities in the same group are not added to a row.
- Lahti municipality code 398 also contains addresses whose postal locality is Nastola. Postal locality alone does not define the municipality filter.
- Etteplan Oyj and Etteplan Finland Oy, and the Koiviston Auto companies, have distinct Business IDs. They remain separate when each meets the address and financial-observation rules.
- Fiscal years 2024 and 2025 appear together. The figures are not same-calendar-year market shares.
- Revenue measures the whole legal entity, not only sales generated in Lahti.
- Financial and register data change. Ranks can move after a new filing, address change, merger, demerger, or register update.
