Ruby on Rails in Wrocław, ranked for 2027

Best Ruby on Rails software houses in Wrocław

Poland has a strong Rails community from the 2010s, and several houses still specialize in it. Ask about upgrades across Rails major versions, because that is where old apps get stuck. I found 13 companies with an office in Wrocław that show Ruby on Rails work in at least one source (10 by their Clutch profile, 1 by their open roles on JustJoin.it, 4 by my Wrocław catalog), and checked each in the court register, its latest filing and its employee reviews. 6 meet the ranking criteria and the 5 highest scores are below. If one senior engineer is enough, I build SaaS products with AI agents.

In short: The highest-scoring Ruby on Rails software houses in Wrocław for 2027 are Momentum (score 86), Monterail (score 82) and Grape Up (score 81). 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 picks come from the data in the full table, not from who paid. A company enters this list when at least one source shows Ruby on Rails work; the share on Clutch is what the company declares.

The ranking

The order below is the score from five axes: transparency, client reputation, stability, specialization and activity. Here specialization measures how strong the Ruby on Rails evidence is. 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. Open the sources under each entry before you shortlist.

Momentum

Wrocław healthcare software and AI studio, formerly Applover, that builds HIPAA-ready apps and wearable integrations for HealthTech companies.

Clutch: 4.9 (45 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Healthtech companies and clinics that need a patient app, an EHR integration or medical AI from a team that works only in healthcare.

Pros

  • Momentum reported a profit of 1.7M PLN on 25.6M PLN of revenue in 2025.
  • Healthcare apps and FHIR integrations have been its niche since 2020. The site shows an ISO 13485 certificate.
  • Clutch shows 4.9 from 45 reviews. Named case studies include LabPlus, Caily and Villa Medica.
  • Momentum publishes open-source health tools such as Open Wearables, so you can read its code before you sign.

Cons

  • Employee reviews are mixed (23 positive, 19 negative), and 12 of them mention layoffs or cuts.
  • Venture funds own the company through ASI vehicles in KRS, so investors set the growth targets.
  • Clutch lists a minimum project of 50,000 USD. Some Clutch reviews still describe Applover, the old brand.

From their website and Clutch profile

  • Applover rebranded to Momentum in 2024 and narrowed its focus to healthcare, while Clutch reviews still refer to Applover (source: https://www.themomentum.ai/about and https://clutch.co/profile/momentum-previously-applover).
  • ISO 13485 and HIPAA appear only as logos, with no certificate number or certifying body (source).
  • The site gives no headcount and cites 220+ delivered projects and 100+ healthcare applications (source).
  • The HQ address, Gen. Sikorskiego 26 in Wrocław, is the same building Droids On Roids lists (source: https://www.themomentum.ai/lets-talk and https://www.thedroidsonroids.com/).
  • Clutch reports 70 percent of clients in the medical industry, a $50,000 minimum project and $50 to $99 per hour (source).
  • The site promises a reply within 24 hours (source).

Clients they name: LabPlus, Bennabis Health, Egis, Steppie, Villa Medica, Caily

Healthcare web developmentHealthcare mobile developmentHealthcare AI implementationWearable app developmentHIPAA-compliant infrastructure and securityEHR and HL7 FHIR integrationAIRubyDockerPython

Verdict. Pick Momentum for a healthcare product in Wrocław, where its compliance work counts. Outside healthcare look elsewhere, and ask about the layoff mentions on the first call.

Monterail

Product design and software studio (Vue and Nuxt partner) building web, mobile and AI products for global brands since 2010.

Clutch: 4.8 (64 reviews)Rate: 25–49 USD/hMin. project: 10,000 USDPremier Verified

Best for: A funded startup or a brand that wants a known Wrocław name with a big public portfolio, a US office and official Vue and Nuxt partner status.

Pros

  • The largest public portfolio in the city, with named brands such as Pizza Hut, Merck and Polaroid, and 4.8 on Clutch from 61 reviews.
  • Profitable in 2025 (1.2M PLN on 29.3M PLN of revenue) and owned by the founders’ family foundations, so no foreign parent.
  • Official Vue and Nuxt partner, with offices in Chicago and Berlin for clients in those markets.

Cons

  • Employee reviews are mostly negative (6 positive, 16 negative) and 10 of them mention layoffs or cuts; growth by acquisition brings integration pain.
  • Zero open roles on the job boards at the last snapshot, which is unusual for a company of this size.
  • Declared rate band of 25 to 49 USD on Clutch is below the Wrocław norm; ask who works on your project and at what seniority.

From their website and Clutch profile

  • Monterail has the biggest public portfolio in the set, with about 70 case studies naming brands such as Flink, Pizza Hut, Merck and Polaroid (source).
  • Monterail grows by acquisition, buying Untitled Kingdom (2024), ElPassion (2025) and Lakeview Labs (2025) (source).
  • Monterail is the only firm here with a US office (Chicago) and a Berlin address. It is also an official Vue and Nuxt partner (source).
  • The homepage says 400+ clients and 900+ projects, and the site never breaks these numbers down (source).

Clients they name: Flink, Pizza Hut, Merck, Polaroid, SPIE, Convatec

Web developmentMobile appsProduct designAI solutionsMVP developmentStaff augmentationReactVueRubyElixir

Verdict. The best-known name on this list and the best client reviews by volume, dragged down by what its own people say. Hire it for the portfolio, write the team into the contract.

Grape Up

Enterprise cloud, legacy modernization, data platforms and AI engineering for automotive, finance, manufacturing and aviation companies.

Clutch: 5.0 (6 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Automotive, finance and aviation enterprises modernizing legacy systems or building a cloud and data platform, with a budget above 50,000 USD.

Pros

  • Grape Up reported a profit of 27.1M PLN on 92.3M PLN of revenue in 2025.
  • Polish funds and the founders' family foundations own the company. Headquarters are in Kraków, with a Wrocław development center.
  • Grape Up runs its own platforms for legacy modernization and data sharing, such as G.Tx and Databoostr.
  • Clutch shows a 5.0 rating.

Cons

  • Clutch shows only 6 reviews, and only one of 25 case studies names the client. Logos such as Porsche come without described work.
  • GoWork employee reviews are negative (5 positive, 17 negative), with 8 mentions of layoffs, though the latest review is from 2024.
  • The job boards showed 1 open role at the last snapshot.

From their website and Clutch profile

  • Headquarters are in Kraków, and Wrocław is one of two Polish development centers. Grape Up has a Wrocław presence but is not a Wrocław company (source).
  • 24 of 25 case studies are anonymized by sector, and Cummins is the only named client. The homepage logo wall shows image files without text names (source).
  • The about page claims over 20 years of operation but gives no year. The Polish KRS entry is from 2014, and Clutch lists 2006 (source).
  • The site shows no ISO or cloud partner certifications, although Grape Up sells sovereign cloud and AI governance products (source).
  • Clutch shows 5.0 from 6 reviews, a $50,000 minimum project, $50 to $99 per hour and 50 to 249 employees (source).

Clients they name: Cummins

Hybrid cloud engineeringApplication and legacy modernization (G.Tx process)Data platformsAI and advanced analyticsAgentic AI product engineeringOwn products: Cloudboostr, Databoostr, AiboostrReactPythonKubernetesAI

Verdict. Grape Up is profitable but hard to verify from outside, so ask for named references in your industry before you sign. For a startup MVP it is too big.

GP Solutions

Munich-based software group with travel tech roots, selling custom development and dedicated teams from Polish offices.

Clutch: 4.9 (24 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: A travel company or tour operator that needs booking or operations software from a team that knows the domain.

Pros

  • Long travel tech record, with clients like Air Canada, Tallink and Railbookers.
  • Publishes a project floor of 50,000 EUR on its home page.
  • Clutch shows 4.9 from 24 reviews.
  • Lists Ruby on Rails among its technologies, next to .NET, Java and PHP.

Cons

  • The Polish company is small, with a loss of 36K PLN on 1.5M PLN of revenue in 2023.
  • The imprint names only GP Solutions GmbH in Germany, and the Łódź company from KRS is absent from the site.
  • Had zero open roles at the last snapshot and almost no GoWork history.

From their website and Clutch profile

  • The imprint names GP Solutions GmbH in Unterschleißheim near Munich and no Polish company. (source)
  • The imprint lists offices in Kraków, Warsaw and Wrocław, while KRS places the Polish company in Łódź. (source)
  • The home page says medium and large projects start from 50,000 EUR. (source)
  • The home page claims experience since 2002, 300+ projects and a 94% retention rate. (source)

Clients they name: Education First, Mercedes-Benz, Air Canada, Tallink, XING, Migros, Railbookers

Custom enterprise softwareWeb and mobile appsDedicated development teamsLegacy modernizationAI and data analyticsShopify developmentAI

Verdict. GP Solutions fits a travel business with a mid-size budget and a long roadmap. Confirm the contracting entity before you sign.

The Masters

Clutch: 5.0 (7 reviews)Rate: 25–49 USD/hMin. project: 5,000 USD

Pros

  • Owned by private individuals (KRS)

Cons

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 5, 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.

  • Altimi

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.

  • N-iX · Kraków
  • USEO
  • Softjourn
  • Bright Coders' Factory · Opole

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.

  • Qulix

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.

  • Antologic
  • Light Code

What they charge

On Clutch, the companies in this table most often declare 50 to 99 USD an hour. 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.

Check any agency yourself in 10 minutes

  1. Poland has a strong Rails community from the 2010s, and several houses still specialize in it. Ask about upgrades across Rails major versions, because that is where old apps get stuck.
  2. 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.
  3. Read the last financial statement on rejestr.io: revenue, profit or loss, and whether it was filed on time.
  4. Check the VAT white list: active, and the name matches the contract.
  5. On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
  6. On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
  7. Ask who exactly will work on your project, and check those people on LinkedIn.

Questions

What are the best Ruby on Rails software houses in Wrocław in 2027?

By the score on this page: 1. Momentum (86), 2. Monterail (82), 3. Grape Up (81), 4. GP Solutions (61), 5. The Masters (59). 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 do Ruby on Rails agencies in Wrocław charge?

Most companies in this table declare 50 to 99 USD an hour on Clutch. My own rate as a senior engineer working with AI agents is 36 to 54 USD an hour.

How do you know a company does Ruby on Rails?

From at least one of three sources: the service, industry and framework shares on the Clutch profile, the skills in open roles on JustJoin.it, or my own Wrocław catalog. Companies with two or three sources score higher on specialization. The software house finder shows the same tags for every company.

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.

Can I get my company added or corrected?

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

How this ranking was made

  • 1,485companies in the data set
  • 709checked in the National Court Register
  • 454with a financial statement
  • 7,436Clutch listing positions read, paid ones marked
  • 451employee review profiles on GoWork
  • 2+months of data collection, since September 2026

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.
