List of Estonian limited companies (OÜ) that actually converts
Updated 2026-08-30 · 5 min read
The private limited company (osaühing, OÜ) is by far the most common company form in Estonia, so most B2B prospecting projects start from a list of OÜs.
The full list is a poor target group though: it contains dormant companies and sectors you never sell to. Here is how to cut it down to something usable.
What the list must contain
A name and a registry code alone cannot be segmented or synced to a CRM. A usable list always carries size and activity context too.
- Legal name and registry code
- Legal form, so OÜ can be separated from AS, MTÜ and sole traders
- EMTAK/NACE activity and sector
- County and city
- Employee count and turnover band
- General email and phone
How to narrow it down
Narrow segments win: one sector, one region, one size band. 500 correct companies beat 50,000 random rows.
In the Kontabase builder every filter updates the live record count and price, so you can tighten the segment before paying.
