DO OK
NewConnect-listed, four-times ISO certified software and IoT studio serving insurance, proptech, health and edtech clients in Northern Europe.
Best for: Nordic and Benelux clients who need ISO-certified processes (including 27018 for personal data in the cloud) and a team split between Wrocław and Tallinn.
Pros
- Four ISO certificates (9001, 27001, 14001, 27018), the most of any company in the ranking, and a NewConnect listing since 2017.
- 4.8 on Clutch from 42 reviews, offices in Tallinn and Aarhus, 3 open roles on the boards.
- Profitable in 2025 (905K PLN on 13.5M PLN of revenue).
Cons
- Employee reviews are negative (3 positive, 12 negative); read them before you sign.
- A listed company (S.A.), so the shareholders are not in the court register.
- The projects page renders empty without JavaScript, so case studies are hard to find.
From their website and Clutch profile
- DO OK is the only firm in the set with four ISO certificates, including 27018 for personal data in the cloud. It debuted on the Warsaw Stock Exchange (NewConnect) in 2017 (source).
- DO OK has offices in Tallinn and Aarhus, a Dutch branch since 2018 and a Danish one since 2019 (source).
- The founding year conflicts, with 2010 on the site and 2016 in the KRS entry in our file, likely the S.A. conversion (source).
- The projects listing renders empty without JavaScript, so case studies are reachable only via the industries page and direct links (source).
Clients they name: BEHA, Zilveren Kruis (Actify), YOLI, Versa, Optima Sport, Polish Press Agency (FakeHunter)
Verdict. Certificates and a public listing make it the easiest Wrocław agency to pass through a corporate procurement department. The employee reviews are the thing to ask about on the call.
