IOS and Swift in Poznań, ranked for 2027

Best iOS and Swift software houses in Poznań

Przemysław Zalewski · Data verified:

  1. 1 Netguru Well-funded commerce and marketplace businesses that want a known brand to build or scale their platform. 80
  2. 2 Curiosum Startups and scale-ups already on Elixir and Phoenix that need senior engineers to build or rescue the product 78
  3. 3 Apzumi Digital health, medtech and health insurance companies that need compliant apps, AI features or software for a 73

I checked 24 companies with an office in Poznań that show iOS and Swift work in at least one source (24 by their Clutch profile, 1 by their open roles on JustJoin.it) against the court register, their latest filing and their employee reviews. 11 meet the ranking criteria, and the 10 highest scores are below. If one senior engineer is enough, I build mobile apps with AI agents.

In short: The highest-scoring iOS and Swift software houses in Poznań for 2027 are Netguru (score 80), Curiosum (score 78) and Apzumi (score 73). 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.

  • One senior instead of a team If the project fits one person with coding agents, hire me for mobile 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 iOS and Swift 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 deep the company goes into iOS and Swift (its share of the Clutch profile and of open roles) and weighs 35% instead of 15%, so specialists rank above large generalists. 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.

Netguru

Poznań digital product company focused on commerce platforms, marketplaces, AI and design for large brands.

Clutch: 4.8 (73 reviews) Rate: 50–99 USD/h Min. project: 50,000 USD Premier Verified

Best for: Well-funded commerce and marketplace businesses that want a known brand to build or scale their platform.

Verdict. Pick Netguru for a well-funded commerce or marketplace build with a known brand behind it. Check team continuity first, given the staff opinions and freelance hiring.

Pros

  • Netguru reported a profit of 6.3M PLN on 127.5M PLN of revenue in 2025.
  • Clutch shows 73 reviews averaging 4.8, and named clients include IKEA, Volkswagen and Żabka.
  • Netguru is a certified B Corporation, per its own site.
  • Netguru hires a lot on the job boards, almost all roles remote.

Cons

  • GoWork opinions lean negative, with 25 positive against 73 negative and 24 mentions of layoffs.
  • Open roles are listed as freelance, so part of the team may be contractors hired per project.
  • Clutch lists IT staff augmentation among its services, so check whether you get a team or individuals.

From their website and Clutch profile

Curiosum

Poznań Elixir and Phoenix specialists that build web apps and SaaS and run open source projects and meetups.

Clutch: 5.0 (8 reviews) Rate: 50–99 USD/h Min. project: 25,000 USD

Best for: Startups and scale-ups already on Elixir and Phoenix that need senior engineers to build or rescue the product.

Verdict. Hire Curiosum when Elixir is already your technology. If you have not chosen one yet, Elixir alone is no reason to hire them.

Pros

  • Claims 50+ Elixir projects and publishes open source libraries, a newsletter and monthly meetups.
  • Holds a 5.0 rating on Clutch from 8 reviews and names Lonely Planet and MEDICE in case studies.
  • Revenue reached 4.1M PLN in 2025, and KRS lists two private individuals as owners.

Cons

  • The 2025 profit was close to zero on 4.1M PLN of revenue, which leaves little financial cushion.
  • The company dates from 2020, the site shows about 13 people, and the job boards list no open roles.
  • Rates run from 50 to 99 USD, and Elixir is a niche technology that narrows your future hiring pool.

From their website and Clutch profile

  • The site claims 50+ Elixir projects and publishes open source libraries and an Elixir newsletter (source).
  • The company page gives 2020 as the official founding year and shows a team of 13 people (source).

Clutch: 4.9 (49 reviews) Rate: 50–99 USD/h Min. project: 10,000 USD Premier Verified

Best for: Digital health, medtech and health insurance companies that need compliant apps, AI features or software for a medical device.

Cons

  • The 2025 filing shows 14M PLN of revenue but only 68K PLN of profit, a thin margin.
  • Site figures do not match: 90+ projects in one place and 150+ in another.
  • ISO 13485 is described as compliance, not a certificate, so confirm what your regulator needs.
  • Narrow focus on health, fitness and insurance.

From their website and Clutch profile

  • The about page says the company started in 2013 and claims 13+ years on the market, 150+ completed projects, 70+ people and 15+ markets (source).

  • Case studies include Zbadani.pl for Synektik, Calpro as software certified as a medical device, and Perkk Check for Medavie; the home page covers HL7 FHIR, DICOM, HIPAA and IEC 62304 (source).
  • The home page shows 90+ projects and 12+ markets in one block and 150+ products in 16 markets in another, so the site's own figures differ (source).

  • The site address differs from the KRS address in Poznań.

From their website and Clutch profile

Best for: Regulated-sector companies that need software built to pass a DORA, NIS2 or GDPR audit.

Best for: Founders who want a fixed-price MVP or a rescue of a Lovable or no-code prototype, with prices known up front.

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

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.

  • DevPark

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.

  • Prograils

Website not confirmed

The website could not be tied to the registered company. Without that I cannot tell whose filing and reviews I am reading, so the company is not ranked.

  • B-MIND Software House

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.

  • Flutter Development AA+

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.

  • INVESTIT Systems
  • NextApps
  • codecreed

Weak evidence for iOS and Swift

They meet the data criteria, but the topic rests on a small Clutch share, a few job ads or a single source. They may do it; the data just does not show it.

  • VAO
  • The BitByBit Company
  • Red Rocket Software
  • Appunite
  • Zealous System
  • Beetroot AB
  • Onix-Systems

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.

25-49 USD/h 8
50-99 USD/h 14
100-149 USD/h 0
150-199 USD/h 0
Rates declared on Clutch, 22 companies with an office in the city.

Check any agency yourself in 10 minutes

  1. Ask for apps they shipped and still maintain, with the App Store link. Native iOS costs more than cross-platform, so it pays off for apps that lean on the device.
  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 in the Financial Documents Repository (free, by KRS number): 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 iOS and Swift software houses in Poznań in 2027?

By the score on this page: 1. Netguru (80), 2. Curiosum (78), 3. Apzumi (73), 4. Expansio (73), 5. APPVERK (72). 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 iOS and Swift agencies in Poznań 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 iOS and Swift?

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

  • 1,487 companies in the data set
  • 722 checked in the National Court Register
  • 453 with a financial statement
  • 7,436 Clutch listing positions read, paid ones marked
  • 690 employee 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 and the Financial Documents Repository 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

  • 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.
  • 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.
