Zielona Góra software companies

Software houses in Zielona Góra: local directory

Przemysław Zalewski · Data snapshot:

  1. 1 DO OK 76
  2. 2 Crehler 63

Zielona Góra has distinct software suppliers rather than one interchangeable agency market: Codetain focuses on e-mobility, CREHLER and SoftCareHouse offer Shopware commerce, SOLTIX and Exergy Group build business systems, and CSL Software and 4Evolve offer security-related work. Astec is a Rublon Services brand; DO OK and GlobalLogic list local offices as part of larger organizations. This directory separates those specialisms from the evidence required for a ranking. Coverage currently includes 12 company records. Only 2 meet the existing eligibility and score thresholds; the other records remain in the directory without a rank. This is a partial directory, not an exhaustive city ranking.

Companies meeting the criteria

DO OK

NewConnect-listed, four-times ISO certified software and IoT studio serving insurance, proptech, health and edtech clients in Northern Europe.

76/100

Clutch: 4.8 (42 reviews) Rate: 50–99 USD/h Min. project: 5,000 USD

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.

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.

Pros

  • Net profit of 905,000 PLN in 2025 on 13,500,000 PLN revenue. (2026-09-22 · source)
  • Clutch rating of 4.8/5 from 42 client reviews. (2026-10-28 · source)
  • Published projects: BEHA, Zilveren Kruis (Actify), YOLI.
  • The contact page lists an office in Zielona Góra. (2026-11-02 · source)

Cons

  • GoWork records 3 positive and 12 negative reviews. These are user opinions, not independently established events. (2026-09-22 · source)
Projects & technologies

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).

Unranked records and coverage gaps

On the city’s Clutch list, but based elsewhere 1

Clutch shows them on this city’s page, but KRS records and the data set do not confirm an office here. They count in the ranking of the city where their office is confirmed, if this site has one.

  • 4Evolve

Ranked 11th and below 1

They qualify but score lower. Their full rows are in the table below; the gap between 10th and 15th is often a few points.

  • SOLTIX Software House

Too little client evidence, under 10 people, sole traders 8

Without 5 Clutch reviews or 2M PLN of revenue in a filing there is no fair way to compare a company with the rest. That is a data gap, not a verdict.

Check any agency yourself in 10 minutes

  1. Find the legal entity in the National Court Register: the seat, the share capital and the shareholders. An office here with a seat in another city is a sales office, not a team.
  2. Read the last financial statement in the Financial Documents Repository (free, by KRS number): revenue, profit or loss, and whether it was filed on time.
  3. Check the VAT white list: active, and the name matches the contract.
  4. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
  5. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
  6. Ask who exactly will work on your project, and check those people on LinkedIn.

How this works: I write back with my own offer and forward your brief to the agencies that fit, after you agree. As of November 2, 2026 no agency pays me for leads and this page has no affiliate links. If that changes, it will say so here.

Questions

Is this a complete ranking of Zielona Góra software houses?

No. It is a partial directory based on the linked records. Only companies meeting the existing eligibility rules and score threshold receive a rank; missing evidence does not imply poor quality.

How are local offices established?

The directory links the company contact pages and available registry records. A registered headquarters and a delivery office can be in different cities.

How this ranking was made

  • 1,494 companies in the data set
  • 728 with KRS records
  • 453 with a financial statement
  • 7,436 Clutch listing records
  • 690 employee review profiles on GoWork

Sources: Clutch profiles and listings, KRS records, available financial statements from rejestr.io and the Financial Documents Repository, GoWork reviews, JustJoin.it and No Fluff Jobs listings, and the Wrocław company catalog. Coverage varies by company; dates and links accompany the available records. The 0 to 100 score combines five axes: transparency, client reputation, stability, specialization and activity. Paid Clutch placements do not increase the score.

Disclosures

  • Until November 2026 I work at Sanddev (Wrocław) as the founding engineer of its Sandtime product. Sanddev appears in the full table with the same score as everyone else and no editorial favor.
  • No agency pays for a position, there are no affiliate links. If any of that changes, the disclosure changes first.
  • My business interest is on every page: I sell senior engineering with AI agents as the alternative to hiring an agency.
  • Written with AI (Claude) from the data set. Every number in the editorial text is checked automatically against the company record or the research notes, source links and dates accompany the available company records.
