React in Warsaw, ranked for 2027

Best React software houses in Warsaw

Przemysław Zalewski·Data verified: ·22 min read

Ask which React version and framework the team ships today and who owns the design system. A team that only lists React next to ten other frameworks usually staffs whoever is free. I found 168 companies with an office in Warsaw that show React work in at least one source (154 by their Clutch profile, 16 by their open roles on JustJoin.it, 1 by my Wrocław catalog), and checked each in the court register, its latest filing and its employee reviews. 135 meet the ranking criteria and the 10 highest scores are below. If one senior engineer is enough, I build React apps with AI agents.

In short: The highest-scoring React software houses in Warsaw for 2027 are BlueSoft (score 85), Innowise (score 84) and Andersen (score 82). 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.

Which company fits your project

  • BlueSoftReact is 25% of the technology focus on its Clutch profile. 4 open roles with React in the requirements. Score 85, 4.8 on Clutch from 13 reviews, profit in 2025.
  • InnowiseReact is 10% of the technology focus on its Clutch profile. Score 84, 4.9 on Clutch from 73 reviews, profit in 2025.
  • AndersenReact is 10% of the technology focus on its Clutch profile. Score 82, 4.9 on Clutch from 129 reviews, profit in 2025.
  • DeveltioReact is 20% of the technology focus on its Clutch profile. Score 82, 5.0 on Clutch from 41 reviews, profit in 2025.
  • One senior instead of a teamIf the project fits one person with coding agents, hire me for React apps before you pay an agency margin.

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 React 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 React 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.

BlueSoft

Warsaw enterprise integrator owned by Orange Polska, focused on data, integration, cloud and AI for banks, telecom and retail.

Clutch: 4.8 (13 reviews)Rate: 50–99 USD/hMin. project: 50,000 USD

Best for: Banks, telecoms and large retailers that need integration, data platforms or managed services from a vendor with a corporate owner.

Pros

  • BlueSoft reported 300.9M PLN of revenue and a profit of 43.8M PLN in 2025.
  • Orange Polska has owned BlueSoft since 2019, which helps with procurement and continuity.
  • Named case studies cover Canal+, Biedronka, GATX and Hellenic Cables. Clutch shows 4.8 from 13 reviews.
  • The job boards showed 72 open roles at the last snapshot.

Cons

  • GoWork employee reviews are negative (13 positive, 39 negative), with 2 mentions of layoffs.
  • The minimum project is 50,000 USD and the processes are enterprise-grade, so an MVP is a poor fit.
  • Many case studies are for Orange companies, the owner, so outside references are fewer than they look.

From their website and Clutch profile

  • BlueSoft has belonged to the Orange Polska group since 2019, together with Craftware and Essembli (source).
  • Several case studies are for Orange companies, the owner, next to clients such as Canal+, Biedronka and GATX (source).
  • The site claims 1000+ experts and 200+ active clients and says it is hiring 118 people (source).
  • The site shows partner logos for AWS, Microsoft, Google, MuleSoft, Salesforce and Databricks (source).

Clients they name: Orange Polska, Canal+, Biedronka, GATX, Hellenic Cables, Raiffeisen Bank

Custom software developmentData platforms and BISystem integration (MuleSoft)Cloud migrationAI agents and document processingManaged servicesJavaPythonTerraformPostgreSQL

Verdict. Pick BlueSoft for corporate integration, data and managed services backed by a telecom group. For a startup or a single small product, it is too heavy.

Innowise

Very large outsourcing and staff augmentation company with a Warsaw headquarters claim and a catalog covering almost every technology.

Clutch: 4.9 (73 reviews)Rate: 50–99 USD/hMin. project: 10,000 USD

Best for: Teams that must add several developers quickly and can manage an outsourced team under their own tech lead.

Pros

  • The Polish company reported 251.2M PLN of revenue and a profit of 3.0M PLN in its 2025 filing.
  • Clutch shows 4.9 from 73 reviews.
  • GoWork employee reviews lean positive, with 65 positive and 10 negative.
  • The site lists ISO 9001, ISO 27001 and ISO 13485.

Cons

  • The margin is thin, with profit at about one percent of revenue.
  • The case studies page names no clients and warns that details may be generalized or modified. The portfolio cannot be checked.
  • The Polish company dates from 2021, while the site claims 2007. The footer gives a registered address in Boston, and the job boards showed no open roles at the last snapshot.

From their website and Clutch profile

  • The about page claims 3,500+ people, 1,600 projects and a founding year of 2007. The Polish company in KRS dates from 2021 (source).
  • The FAQ names Warsaw as headquarters, while the footer gives a registered address in Boston, MA (source).
  • The case studies page names no clients and warns that client details may be generalized or modified (source).
  • Innowise sells staff augmentation openly, promising CVs in 1 to 2 days and a team joining in 3 to 5 days (source).

Clients they name: Hays, Spar, Tietoevry, Topcon, NTT Data, Commercial Bank of Qatar

Custom software developmentStaff augmentation and dedicated teamsTesting and QAData, AI and MLERP and CRMLegacy modernizationAI

Verdict. Use Innowise for staff augmentation under your own tech lead when you need CVs fast across many technologies. Skip it when you need a partner whose past work you can verify.

Andersen

Large international outsourcing company headquartered in Warsaw, selling dedicated teams and full-cycle development in 22 industries.

Clutch: 4.9 (129 reviews)Rate: 50–99 USD/hMin. project: 50,000 USDVerified

Pros

  • Clutch shows 129 reviews with a 4.9 rating and a Verified badge.
  • The Polish company reported 177.1M PLN of revenue in its 2025 filing.
  • Andersen has headquarters in Warsaw and a Kraków development center. Its named work includes Deutsche Telekom and Samsung Electronics.

Cons

  • The margin is near zero, with a profit of 363K PLN on 177.1M PLN of revenue.
  • The Polish company dates from 2019, while the group claims 19 years. Other entities sit in Lithuania and Germany.
  • Our GoWork data has no employee reviews, and the job boards showed no open roles at the last snapshot. The minimum project is 50,000 USD.

From their website and Clutch profile

  • The about page claims 3,500+ in-house experts, 2,000+ clients, 18 offices and 19 years of experience, with Warsaw as headquarters (source).
  • The footer names other legal entities, UAB Andersen Soft and Andersen Germany GmbH, so the Polish company is one of several (source).
  • Many case studies are under NDA, and the named ones include Deutsche Telekom and Samsung Electronics (source).
  • The site announces the Claude Partner Network and AWS MSP partnership (source).

Clients they name: Samsung Electronics, Deutsche Telekom, BNP Paribas, Verivox, TUI

Custom software developmentStaff augmentation and dedicated teamsAI and dataCloud and DevOpsCybersecurityCRM and ERPAI

Verdict. Use Andersen to scale a team you lead, backed by 129 Clutch reviews. Check who signs the contract, given the thin Polish margin and the multi-entity setup.

Develtio

Warsaw web and app studio born from an ad agency, mostly WordPress, PHP and mobile work, now selling AI sprints.

Clutch: 5.0 (41 reviews)Rate: 25–49 USD/hMin. project: 5,000 USD

Best for: Small businesses that need a WordPress site, a web app or a simple mobile app at offshore-band rates.

  • Clutch shows a 5.0 rating from 41 reviews, with reviewers such as Skanska, Orange Polska and Hitachi.
  • The site has named case studies for Hitachi's HVAC branch, Biletyna and Kiddoways.
  • Clutch lists a minimum project of 5,000 USD.

Cons

  • Develtio reported 4.2M PLN of revenue and a profit of 51K PLN in 2025. The site claims 60+ people on one page and 40+ on another.
  • Employee reviews are mixed (3 positive, 3 negative), with 3 mentions of layoffs.
  • Business directories list greenlead.pl as its website, while the company site is develtio.com.

From their website and Clutch profile

  • Team size claims disagree, with 60+ on the homepage and 40+ on the about page (source).
  • Develtio grew out of Green Parrot, an advertising agency, and was founded in 2017 (source).
  • Half of the six visible case studies do not name the client (source).

Clients they name: Hitachi (HVAC branch), Biletyna, Kiddoways, IPMA, BNP Paribas

Web development and WordPressMobile appsAI development and chatbotsCustom softwareWebsite maintenance (SLA)Search experience optimizationAI

Verdict. Develtio fits websites and small apps, where its client reviews matter more than scale. The filings do not support the team size on the site, so ask who will do the work.

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 10, 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.

  • Brights (paid)
  • Geniusee (paid)

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.

  • KITRUM

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.

  • Ideamotive
  • Team Connect
  • ALTEN Polska
  • ITDS
  • B3 Consulting Poland
  • EffectiveSoft

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.

  • MITRIX Technology

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, 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.

Rates declared on Clutch, 145 companies with an office in the city. In brackets: companies “serving” the city without an office.

Check any agency yourself in 10 minutes

  1. Ask which React version and framework the team ships today and who owns the design system. A team that only lists React next to ten other frameworks usually staffs whoever is free.
  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 React software houses in Warsaw in 2027?

By the score on this page: 1. BlueSoft (85), 2. Innowise (84), 3. Andersen (82), 4. Develtio (82), 5. Order Group (80). 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 React agencies in Warsaw 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 React?

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.
