Methodology
How was the Seinäjoki 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, the current Seinäjoki municipal population was verified on October 24, 2026 and every published revenue row was checked against DM Faster financial data.
1. Registry foundation
DM Faster's PRH-backed location data identified 4,862 Seinäjoki observations.
2. Company normalization
Current address under municipality code 743, active trade-register status, legal name, and Business ID were normalized. This produced 4,701 active entities.
3. Financial enrichment
DM Faster's financial enrichment connected an exact 2024 or 2025 revenue observation to 319 companies.
4. Ranking
Business ID formatting variants were unified, current legal names were restored from PRH, and the 30 largest entities were ranked by revenue.
How to read the ranking
- The population contains active legal entities with a current PRH visiting or postal address under municipality code 743.
- The ranking uses the latest exact DM Faster revenue observation from fiscal year 2024 or 2025.
- Revenue measures the full legal entity, not only sales generated in Seinäjoki or at one local establishment.
- Financial and registry data update over time, so ranks can move after a new filing or registry change.
