I checked 121 companies with an office in Warsaw that show iOS and Swift work in at least one source (116 by their Clutch profile, 7 by their open roles on JustJoin.it) against the court register, their latest filing and their employee reviews. 44 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 Warsaw for 2027 are GLOBALDEV (score 90), itCraft (score 89) and Order Group (score 86). 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.
GLOBALDEVProduct company that wants to add AI-focused engineers to its own team for months. IOS and Swift is 100% of the technology focus on its Clutch profile. Score 90, 4.9 on Clutch from 116 reviews, profit in 2025.
itCraftHealthcare and retail companies that need a mobile app built and maintained by an ISO-certified team with named references. IOS and Swift is 50% of the technology focus on its Clutch profile. Score 89, 5.0 on Clutch from 71 reviews, profit in 2025.
Order GroupEnergy, IoT and fintech companies that need EMS, device or lending software in React and React Native, with UX/UI design included. IOS and Swift is 50% of the technology focus on its Clutch profile. Score 86, 5.0 on Clutch from 19 reviews, profit in 2025.
ElinextEnterprises that need a large outsourced team for testing and QA alongside custom development. IOS and Swift is 50% of the technology focus on its Clutch profile. Score 85, 4.9 on Clutch from 46 reviews, profit in 2025.
One senior instead of a teamIf 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 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.

Order Group
Warsaw software house building energy, fintech, AI and IoT software, from EMS to lending apps and Android systems.
Best for: Enterprises that need a large outsourced team for testing and QA alongside custom development.
Verdict. Use Elinext when you need many testers or developers fast and can work across time zones. For a small team based in Poland, pick a local firm.
Pros
Lists manual, automated, performance and penetration testing as separate QA services.
Shows ISO 9001, ISO 27001 and ISO 13485 badges on its site.
Clutch shows 4.9 from 46 reviews.
Earned 754K PLN of profit on 18.6M PLN of revenue in 2025.
Cons
Most of its 700+ engineers work outside Poland, in centers such as Vietnam and Uzbekistan.
The site gives two QA headcounts, 200+ and 120, so ask who will work on your project.
From their website and Clutch profile
The contact page names Warsaw as headquarters with 220+ employees, plus centers in Vietnam, Uzbekistan, Georgia and Kazakhstan (source).
The services page gives 200+ QA engineers in one place and 120 in-house QA engineers in another (source).
The site dates the group to 1997, while the Polish company entered KRS in 2020 (source).
The home page shows ISO 9001, ISO 27001 and ISO 13485 badges (source).
Best for: Small businesses that need a WordPress site, a web app or a simple mobile app at offshore-band rates.
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.
Pros
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).
Best for: Nonprofits and publicly funded US health programs that want a small team to add generative AI to existing software.
Verdict. Choose Freeport Metrics for an AI feature in a US-facing product built by a small team. For Polish public tenders look elsewhere, since its government work is all in the US.
Pros
Clutch shows 4.8 from 15 reviews.
Its portfolio names clients such as Smile Train and Bangor Savings Bank.
Publishes Form2agent, an open-source toolset for adding AI to existing apps.
Its portfolio tags four US projects as government work.
Cons
Thin margin in 2025, with 126K PLN of profit on 5.3M PLN of revenue.
GoWork shows 11 negative entries and no positive ones.

Every company we checked
The table below has the 121 companies with iOS and Swift evidence in Warsaw, including the ones that do not qualify for the ranking, with the reason. Sort by any column.
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.
Geniusee (paid)
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.

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.
25-49 USD/h54

100-149 USD/h6
150-199 USD/h0
Rates declared on Clutch, 117 companies with an office in the city.
Check any agency yourself in 10 minutes
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.
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.
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.
Check the VAT white list: active, and the name matches the contract.
On the Clutch list hover over the company link; a link through ppc.clutch.co is an ad. Then read the reviews themselves.
On GoWork read the employee reviews, not the stars, and look for layoffs and rotation.
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 Warsaw in 2027?
By the score on this page: 1. GLOBALDEV (90), 2. itCraft (89), 3. Order Group (86), 4. Elinext (85), 5. Develtio (85). 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 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 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.
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.
Przemysław Zalewski, a senior full-stack engineer in Wrocław with 15+ years of shipping software. I ran this catalog for two months while choosing my own next clients, so every number here was useful to me before it was useful to you. I build with coding agents, work with clients in the US and the UK, and I sell the alternative to the agencies on this list.
“a true bias for action” client CTO, public LinkedIn recommendation
Confidential by default. NDA is standard. I never show your project, name or screenshots without written consent, which is why this site names no clients without permission.
Your code, your accounts. Code and data stay in your repository and accounts. AI tools run with training on your data turned off, and secrets never reach a model.
A handover you can use. Every project ends with the same checklist: a README that gets it running, one architecture diagram, written decisions, CI, a runbook and a recorded walkthrough. It is done when someone outside the project can run it from the docs.
Boring technology where it counts. I pick a stack you can hire for. Anything experimental needs your yes and an exit plan.
Approach matched to your risk appetite. Prototype, product or regulated: the level decides how much autonomy the agents get and how much review and validation each change needs.
Everything checkable. Every number on my pages links to its source. My tools are free, and the idea validator skill is open source (MIT).
My pledge
Reply within 24 hours. I reply within 24 hours on working days, personally, not a bot. Weekend messages: by Monday noon.
Late means free. If I am late, the first hour of work is free. You do not have to ask.
Scope in writing within 24 hours. A free 30-minute call with no company deck, then the scope and the price in writing within 24 hours. You decide.
The person who does the work. You talk to the person who does the work. No sales layer, no handoff.
Follow-up only with news. I follow up only when I have something new for you. Never a "did you see my offer".
Honest "not a fit". If I am not the right person, I say so on the call and point you to someone who is.
