About us
An Estonian software company, on the record
3S holding OÜ was entered in the Estonian Business Register on 07.01.2022 and has been engineering software for organisations since. Everything on this page that concerns our legal status is taken from the public register and can be checked there.
Who we are
The short version
We are a small, senior engineering company based in Tartu, Estonia. We build custom software for organisations, advise on cloud and platform architecture, integrate security into the systems we work on, and modernise systems that have become too risky or too slow to change. We work with businesses and institutions, in English, across the EU and internationally.
The register records our principal activity as EMTAK 62101 — Computer programming activities. That is not a formality we are stretching to fit a marketing page: it is precisely the business described on this site.
We are a private limited company (Osaühing (private limited company)) with a share capital of 2 501 €, and we have filed an annual report for every financial year since incorporation. Each of those statements is verifiable in the register linked below.

We publish the fact that each report was filed and accepted, with its submission date, because that is what the register states. We deliberately do not publish revenue or profit figures here: the numbers circulating on third-party company-data sites disagree with one another, and we will not repeat a figure we cannot stand behind. The filed reports themselves are available from the register.

Where we operate
Location and hosting
Our registered office is Purpuri tn 12-2, 51011 Tartu, Tartu maakond, Estonia. That address is the company’s registered seat as recorded in the business register; it is not a walk-in support counter, and we ask that enquiries come by e-mail so they reach the right person.
This website is hosted by Namecheap, Inc. (AS22612) in the United States, which is outside the European Economic Area. We measured that rather than assuming it, and the resulting international transfer is disclosed — with the safeguard it relies on — in our Privacy Policy.
