Software houses in Łódź, ranked for 2027

Best software houses in Łódź

Przemysław Zalewski·Data verified: ·26 min read

Łódź is a smaller market with lower costs and a few established houses; Clutch has no city page for it, so this list comes from the national listing filtered by office location. I read the Clutch listing in full, marked the paid positions, and checked every company with an office here in the National Court Register, its latest financial statement and the job boards. Of the 34 companies with an office or a listing here, 19 meet the criteria for a software house with a real local team. The 8 highest scores are ranked below. I sell the alternative: one senior engineer working with AI agents.

In short: The highest-scoring software houses in Łódź for 2027 are FiveDotTwelve (score 78), Exaco (score 78) and goodylabs (score 78). The 0 to 100 score combines court register data, the latest financial statement, Clutch client reviews, GoWork employee reviews and open roles on the job boards. Paid Clutch positions do not count.

The ranking

The order below is the score from five axes: transparency (seat in KRS, filings, known owners), client reputation (Clutch rating weighted by the number of reviews), stability (profit, revenue, age, employee reviews), specialization and activity (open roles on the job boards). Weights and the full method are on the guide page.

Financial figures come from the latest filing of the Polish company. For subsidiaries of foreign groups they can be far from the size of the real business. Read the pros and cons, then open the sources under each entry.

FiveDotTwelve

Łódź mobile studio that builds Flutter and FlutterFlow apps, from MVPs to IoT and fitness products.

Clutch: 4.9 (38 reviews)Rate: 50–99 USD/hMin. project: 25,000 USD

Best for: Startups and brands that want a Flutter or FlutterFlow mobile app taken from MVP to launch.

Pros

  • Holds 4.9 on Clutch from 38 reviews and has been a recommended Flutter consultant since 2023.
  • Profitable in 2025, with a profit of 246K PLN on 6.9M PLN of revenue, and KRS lists one private owner.
  • The site states 20+ people and 125+ projects and names clients such as Knauf and Autenti.

Cons

  • The team works in Flutter and FlutterFlow, so native-only apps and heavy backend work fall outside its core.
  • The job boards list no open roles, and GoWork has no employee reviews.
  • Its Clutch minimum project is among the higher ones for a team of this size.

From their website and Clutch profile

  • The about page claims 20+ people and 125+ projects (source).
  • Flutter's site has listed FiveDotTwelve as a recommended consultant since 2023 (source).
  • More than 30 named clients give testimonials, from startups to Knauf and Autenti (source).

Clients they name: VRWorkout, Squaddy, Knauf, Autenti, Skra Bełchatów, Widzew

Flutter app developmentFlutterFlow developmentMVP developmentUI/UX design and auditsIoT appsWeb backend and frontendAI

Verdict. Call FiveDotTwelve first for a Flutter app in Poland. For native iOS or a complex backend, add another partner or look elsewhere.

Exaco

Łódź software house that builds web and mobile apps and offers outsourcing and a service desk for maintenance.

Clutch: 5.0 (11 reviews)Rate: 50–99 USD/hMin. project: 10,000 USD

Best for: Polish retailers, schools and public bodies that need a web or mobile app plus someone to run it after launch.

Pros

  • Profitable in the latest filing, with a profit of 1.1M PLN on 8.4M PLN of revenue in 2025.
  • Publishes six named case studies with Polish clients such as Carrefour, Bricoman and AHE Łódź.
  • Holds a 5.0 rating on Clutch from 11 reviews, with reviewers from Carrefour and PWN.
  • Runs a service desk for maintenance after launch, a job many small houses leave to the client.

Cons

  • Clutch puts 30% of its work in IT staff augmentation, so part of the business is body leasing.
  • GoWork employee reviews are mixed, with 9 positive and 6 negative, and one mentions layoffs.
  • Its own pages give different figures for its years in business, and the last snapshot showed zero open roles.

From their website and Clutch profile

  • The home page claims nearly 150 projects and 7 mln+ users of its apps, with no breakdown (source).
  • The about page claims 10+ years of experience and elsewhere refers to the last eight years (source).
  • All six named case studies are for Polish clients such as Carrefour, Bricoman and AHE Łódź (source).
  • Clutch lists 5.0 from 11 reviews, 50 to 99 USD per hour and a 10,000 USD minimum, with reviewers from Carrefour, PWN and Przewozy Regionalne (source).

Clients they name: Carrefour, Bricoman, 3W, Epruf, AHE Łódź (Academy of Humanities and Economics), Invest in Łódź

Web development (Java/Kotlin, Angular, PHP)Mobile development (iOS, Android, Flutter)IT outsourcingService desk and maintenanceBusiness analysisQuality assurance

Verdict. Take Exaco for a retail or education app with years of maintenance. Skip it if you want a product team that publishes engineering work.

goodylabs

Łódź product studio that combines customer experience design, digital commerce and custom engineering for retail and workspace brands.

Clutch: 5.0 (8 reviews)Rate: 50–99 USD/hMin. project: 5,000 USD

Best for: Retail and e-commerce brands that want customer experience design and a loyalty or commerce app from one Łódź studio.

Pros

  • Profitable in 2025, with a profit of 1.2M PLN on 13.2M PLN of revenue.

  • Holds a 5.0 rating on Clutch from 8 reviews and names clients such as Tortoise Media and Triptease.
  • The Clutch minimum project is 5,000 USD, a low entry point.

Cons

  • The site names no clients in text beyond one testimonial, and the case study list shows no readable titles.
  • Clutch shows 10 to 15 employees in Łódź against a company size of 50 to 249, so ask who would work on your project.
  • GoWork has only 2 reviews, both negative, and the last snapshot showed zero open roles.

From their website and Clutch profile

  • The 'proud to work with' logo strip names no clients in text, and the case study list loads as filters without readable titles (source).
  • The contact page mentions offices in Central Europe and the UK but lists only the Łódź address (source).
  • The site names SoDA and the coworking software vendor Nexudus as partners (source).
  • Clutch gives 2012 as the founding year and 10 to 15 employees in Łódź against a company size of 50 to 249. Reviewers include Tortoise Media and Triptease (source).

Clients they name: OTCF

CX strategy and designLoyalty and digital commerceCustomer research and product designProduct healthcheck and UX auditSoftware deliveryBig data managementAI

Verdict. Use goodylabs for a commerce or loyalty app, after asking for three named references. For complex backend engineering, look at a more technical team.

Makimo

Łódź software consultancy that offers code health checks, integrations, maintenance and full builds.

Clutch: 5.0 (11 reviews)Rate: 50–99 USD/hMin. project: 10,000 USD

  • Holds a 5.0 rating on Clutch from 11 reviews and publishes an XTB case study.

  • Sells fixed service packages such as a health check and a care plan, which makes buying easier.

Cons

  • The 2025 profit was 66K PLN on 3.7M PLN of revenue, a thin margin.
  • The site gives no headcount, address or founding year, and Łódź appears only in the privacy policy.
  • The job boards list no open roles, and employee reviews are almost absent.

From their website and Clutch profile

  • makimo.pl redirects to makimo.com, and the Łódź address appears only in the privacy policy (source).

  • Makimo is an AWS Select Tier partner and a SoDA member (source).
  • The listed broker XTB appears as a named case study (source).

Clients they name: XTB, Tune Therapeutics, Vanderbilt University, Winicjatywa, MISZBUD

Codebase health checkIntegrationsMaintenance and reliabilityEnd-to-end developmentAdvisoryTeam mentoring

Verdict. Hire Makimo to fix and maintain a product you already run. For a large new build, its small size becomes the limit.

Codeclusive

Small Łódź team of senior developers that builds and rescues products for founders and often stays for years.

Clutch: 5.0 (10 reviews)Rate: 50–99 USD/hMin. project: 1,000 USD

Best for: Founders who need two to four senior developers to build or rescue a web or Flutter product and stay for years.

Clients they name: Tute, Fuseable, Thanks Mel, Simplifire, Shrap, Yepic

Custom software and platform rewritesRescue of stalled projectsPoC and MVP for foundersFlutter mobile appsLaravel web developmentConversational AI in Clojure

Verdict. Hire Codeclusive when you want two to four seniors for a long partnership. Skip it for a platform that needs a dozen people at once.

TDCM

Łódź team-extension agency that builds web and mobile apps, mostly for small clients in the US, UK and Europe.

Clutch: 5.0 (9 reviews)Rate: 25–49 USD/hMin. project: 10,000 USD

Best for: Small foreign startups that want to add low-rate Ruby on Rails or React Native developers from Łódź to their team.

  • The public team page lists 21 people by name.
  • The portfolio shows specific apps in health, clean energy and maritime, with the technologies listed.

Cons

  • The latest filing in our data shows revenue of only 207K PLN, which does not match a team of 10 to 49.
  • TDCM sells team extension, a form of staff augmentation, and its 25 to 49 USD rate band is the offshore band.
  • KRS dates the company from 2022 while Clutch says 2011, and the only phone number on the site is American.

From their website and Clutch profile

  • The team page names 21 people (source).
  • The about page describes an extended team model in which developers join the client's team as staff augmentation (source).
  • The only phone number on the contact page is a US number, next to a Łódź address (source).

Clients they name: Sea Service, Forté Music, Reinvigoration (OpX), Nazca Health, Wattcrowd

Web apps (Ruby on Rails)Mobile apps (React Native)DevOpsAPIsInternet of ThingsMachine learning

Verdict. Use TDCM for low-cost extra developers, after confirming which legal entity invoices you and who employs the developers. Do not hand it a whole product.

Polar Night Software

Finnish-Polish software company with senior teams in Łódź that builds healthcare, data and custom platforms for Nordic clients.

Clutch: 4.8 (8 reviews)Rate: 50–99 USD/hMin. project: 10,000 USD

  • Focuses on healthcare and has a compliance advisor on the team.

  • The last snapshot showed zero open roles, and GoWork has no employee reviews.

From their website and Clutch profile

Clients they name: Medixine, Renta, Efecte, Robu, GroundHawk, FleetGuru

Healthcare and MedTech softwareData and AIFull-stack web and mobile developmentDevOps and cloudAudits, migrations and AI prototyping sprintsTeam extensionAI

Verdict. Choose Polar Night Software for Nordic or healthcare work with a small senior team. Ask for financials newer than 2024 first, because that year closed with a loss.

Inwedo

Łódź .NET house that modernizes legacy business systems and adds AI and process automation for manufacturers.

Clutch: 4.6 (9 reviews)Rate: 50–99 USD/hMin. project: 5,000 USD

.NET and web developmentLegacy app modernizationAI integration (Model Context Protocol)Process automation and monitoringTeam extension and dedicated teamsSoftware testing and QAAI

Verdict. Pick Inwedo for an old .NET system in a factory or back office. Given the 2025 loss and the employee reviews, write the team names into the contract.

All companies in the data set, with the same score. Companies without a confirmed office, sole traders, body-leasing firms and product companies are listed but not ranked.

Who is not in the top 8, and why

Paid placements and “serves the city” without an office

On the Clutch city list the first positions are bought with ads (links through ppc.clutch.co) or a “serves” entry. These companies have no office in the city according to KRS or their own site, so they are not ranked here.

None in this city.

Struck off the register or in liquidation

They still show up on other people’s “best of” lists. Here they appear only in the full table.

None in this city.

Body leasing, product companies and other services

Renting people into someone else’s team is a different service from delivering a project. A product company, a marketing agency or an SAP partner does not sell software projects either. They are in the full table with a label.

  • Happy Team
  • Lowgular

On the city’s Clutch list, but based elsewhere

Clutch shows them on this city’s page, but KRS and our data do not confirm an office here. They are ranked in their own city.

None in this city.

Ranked 11th and below

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

Too little client evidence, under 10 people, sole traders

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.

What they charge

On Clutch, agencies with an office in Łódź most often declare 50 to 99 USD an hour. 0 positions on the city list were paid placements or “serves the city” entries from abroad, usually at 25 to 49 USD. The rate is what the agency bills; the developer on your project is paid less than half of it.

For comparison, my own rate is 36 to 54 USD an hour (45 USD base, pricing). The cost estimator shows what a project like yours costs with and without coding agents.

Rates declared on Clutch, 32 companies with an office in the city. In brackets: companies “serving” the city without an office.

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 on rejestr.io: 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.

Questions

What are the best software houses in Łódź in 2027?

By the score on this page: 1. FiveDotTwelve (78), 2. Exaco (78), 3. goodylabs (78), 4. Makimo (77), 5. Codeclusive (74). The score adds up transparency in the court register, client reviews on Clutch, profit and stability in the latest filing, specialization and current hiring. The full table shows every company checked.

How much does a software house in Łódź cost?

Most agencies with an office in Łódź declare 50 to 99 USD an hour on Clutch, with minimum projects from 5,000 to 25,000 USD. My own rate as a senior engineer working with AI agents is 36 to 54 USD an hour.

Why is a well-known agency not in the top 10?

The full table shows every company with its score. Known names drop when the last filing shows a loss, when Clutch reviews are few, or when the company rents people instead of delivering projects. Some have their seat in another city and only a sales office here.

Did any company pay to be on this list?

No. There are no paid placements and no affiliate links. The only business interest is mine: I sell senior engineering as the alternative to an agency.

How often is the data updated?

Every entry shows the date each source was checked. The plan is a full refresh every quarter.

Can I get my company added or corrected?

Yes. Write to ciunkos@gmail.com with the KRS number and the correction.

The company list comes from a full read of the Clutch city listing (every page, with paid positions marked by their ppc.clutch.co links), the ITCORNER cluster, Google results and job ads. Every company was checked in the National Court Register (KRS) for its seat, legal form, capital and shareholders, in rejestr.io for revenue and profit from the latest filing, on GoWork for employee sentiment, layoff mentions and review clusters, and on the JustJoin.it and No Fluff Jobs boards for open roles and the stack they actually pay for. The 0 to 100 score is five axes with published weights: transparency, client reputation, stability, specialization, activity. A paid Clutch placement does not raise the score.

Disclosures

  • I worked at Sanddev (Wrocław) as the founding engineer of its Sandtime product until November 2026. Sanddev appears in the full table with the same score as everyone else and no editorial favor.
  • As a contractor I have talked with, or applied to, some of the agencies on these lists. None of them knew about this ranking and none of it changed a score.
  • No agency pays for a position, there are no affiliate links, and no company has seen its entry before publication. 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, and every top entry was read against the company’s own website. Sources and check dates are under each entry.
