TL;DR · 30 SECONDS
- The “top 10 software houses in Kraków” ranking is useless for most projects. Paid rankings show companies that have paid for a spot. Clutch shows companies that have received the most reviews. None of this answers the question, “Who will do MY project well?”
- A better criterion: niche specialization. There are 50+ software houses in Kraków. Each one is good at 1-2 areas and average at the rest. The question is not “who is the best” but “who is the best FOR MY scope”.
- Five areas + examples of well-known companies in each area: mobile (Miquido), fintech/iGaming (CrustLab), automotive (Spyrosoft), enterprise IT (Softelnet), digital transformation of B2B sales (JSON Crew—that’s us).
- 5 questions to ask every agency BEFORE you sign: Who owns the copyright, where are the repositories hosted, who specifically is working on this, what exactly does the SOW cover, and what are the terms for termination? These same questions apply regardless of the city.
Niche specialization: an agency with 5+ projects in a single niche area (e.g., B2B configurators, fintech, automotive ECUs, mobile health). It offers predictability: they know the industry’s edge cases, have working architecture templates, and have already made the mistakes you’re making for the first time. The opposite: a generic “we do everything” agency—more expensive or less capable in every area, sometimes both.
A founder googles “software house Kraków” at 10 p.m. The first page of Google: 50 companies. Each claims to be the best, has a 4.9/5 rating on a paid ranking and an impressive case study. After an hour of scrolling, the founder has more questions than at the start.
You know the feeling. Frustration, confusion, and indecision. Because every company looks like the best option, every ranking highlights different leaders, and you have 60,000 PLN and three months to make a decision that will determine the product.
Why rankings are a dead end
A ranking won't tell you who will do a good job for you. He'll just say who bought their spot in the rankings (paid websites) or Who has asked the most clients for reviews on Clutch (Clutch.co, a global review site). That’s why both sources, though legitimate, are useless when it comes to deciding “who I’m going to give 60,000 PLN and three months of my life to.”
That is why this article does not present a ranking. It shows five specialization categories in Krakow, well-known examples of companies in each category (with a link to the official website and Clutch), and five questions These are questions you should ask every agency, regardless of the city. Also, a quick note at the end: JSON Crew (that’s us) is one of the companies listed. We think that’s fair, since we describe our own specialization just like any other.

Why is the “top 10 software houses in Kraków” list useless for most projects?
Because the "Top 10" isn't the Top 10 for you. In reality, it's the Top 10 for the ranking algorithm or the editorial team of the website publishing the list. The algorithm looks at ratings (Clutch, Google, GoodFirms), the number of reviews, advertising fees, and length of time in the industry. Meanwhile, your project looks at something else: whether the agency can do EXACTLY what you need, within the time and budget you have.
The second thing: Kraków is home to more than 200 software companies, according to ClutchMost rankings feature the same top 20 companies in varying orders. These 20 companies do a little bit of everything, which means they’re average for your niche. Niche specialists (companies with 10–30 employees that handle 5+ projects per year in a single field) usually don’t appear in the overall top 10 because they have fewer reviews overall.
The third reason: the ranking confuses two different questions
First question: “who is a good software house in Kraków in general?” Answer: the same 20 companies in every ranking. Second question: “who will build my B2B Product configurator with a Comarch ERP integration in 8 weeks for PLN 50,000?” Answer: 3-5 companies in all of Kraków, none of which are in the overall top 10.
As a result, confusing these two questions leads to a situation where the founder hires a company from the top 10 of the overall ranking, gets a generic discovery process, a generic tech stack, and generic delivery, and after six months asks, “Why didn’t this work out?” In our opinion, it didn’t work out because the question was flawed from the start.
Five areas of specialization with well-established companies
For each category, we list 1-2 publicly known Kraków companies with a link to their official website and a description of their niche. This is NOT a ranking. It's a map that helps you see that the “top 10″ is a false simplification. The real decision starts with the question “which area does my project fall into”.
Area 1. Mobile-first, AI, e-commerce
In our opinion, a company that is well-positioned in this niche is Miquido. Best known for mobile development (iOS, Android, Flutter) and AI implementations for e-commerce, finance, and healthcare. Holds Google Certified Agency status, with a client base of over 100 companies. According to their own statement, 9 out of 10 projects come from referrals. Profiles on Clutch with verifiable reviews.
When it makes sense: you're building a large-scope mobile app, you have a budget of PLN 200k+, and the project needs AI features (recommendations, NLP, computer vision). Miquido isn't cheap, but for this niche it's one of the safe options in Kraków.
Area 2: iGaming, fintech, payment systems
In our opinion, a company that is well-positioned in this niche is CrustLab. Specializing in iGaming, fintech, and health. Full end-to-end (discovery, architecture, UX/UI, development, QA, maintenance). Profile on Clutch publicly verifiable.
When it makes sense: you're building a betting platform, an online casino, B2B/B2C payments, or a fintech system with compliance requirements (PSD2, KYC). A narrow niche requires knowledge of the regulations, which a generic firm probably doesn't have.
Area 3. Automotive, ECUs, embedded systems
In our opinion, [company name] is well-positioned in this niche Spyrosoft. Cited in industry analyses as a safe bet for the automotive sector. Specialization: automotive software, ECUs, embedded systems, and real-time software for autonomous vehicles.
When it makes sense: You’re a Tier 1 or Tier 2 supplier to an automaker and need software for ECUs, ADAS, infotainment, and telematics. This narrow niche requires expertise in AUTOSAR, ISO 26262 (functional safety), and MISRA C (coding standard). A generic agency can’t handle this.
Area 4. Enterprise IT, integrations, custom systems
In our opinion, a company that is well-positioned in this niche is Softelnet. Established in 2001, the company specializes in custom IT systems for businesses looking to streamline their business processes. Java-based, integrations with legacy systems, long-term maintenance.
When it makes sense: you have a company with over 500 employees, a legacy system from 2010 that needs to be rebuilt, and enterprise-scale integration with SAP/Oracle/Comarch. Niche industry expertise and vendor stability are more important than a “modern tech stack.”
Area 5. Digital Transformation of B2B Sales (configurators, dashboards, IoT, automation)
He's sitting here JSON Crew—that’s us. Over the past four years, we’ve implemented configurators and client panels for dozens of manufacturing companies in Poland. Most of them came to us after their first, unsuccessful collaboration with a generic agency. In our opinion, we describe our own niche just as honestly as the other companies in this article. Specialization: Product configurators (Three.js plus dedicated pricing rule engines), customer panels and quote portals, IoT dashboards (energy, manufacturing, smart home), sales automation (CRM, quoting, ERP integrations). Plus our own SaaS product JSON Hub for existing customers.
When it makes sense: You’re a B2B manufacturing company with 50–500 employees, you have a product catalog with variants (tiles, doors, windows, machines), and the quoting process takes days and is a source of losses. Or: You’re building a SaaS product with a configurator as a core feature, and you need a dedicated pricing engine instead of a no-code solution.
When it doesn't make sense: you're building an iOS mobile app, an iGaming project, an automotive project, or an enterprise legacy migration → go to companies in areas 1–4. We’ve written a separate article on how to choose a software development company after an unsuccessful collaboration.
What you won't find in any ranking, but should check out
Every company in the ranking has a 4.5+ rating on Clutch. Unfortunately, that doesn’t tell the whole story. The real criteria that influence a project’s success are largely invisible in rankings.
| Criterion | Version from the ranking | What's really worth checking out |
| Experience | Years in business, number of projects | Number of projects in YOUR niche over the past 24 months |
| Technology stack | List of 30+ technologies | Should we use a public stack (React/Node/Postgres) or our own framework (vendor lock-in)? |
| Case studies | Client logos, general description | The facts: user numbers, integrations, edge cases, and key metrics |
| Team | “50–100 people, 80% of whom are seniors” | The specific people assigned to YOUR project, including their names and working hours |
| Price | "Custom quote after consultation" | Written SOW with a scope change procedure and an IP transfer clause |
| Rating | 4.5/5 on Clutch | 3 references from former clients whom you can call personally to ask |
Five questions to ask every agency BEFORE you sign
These questions don’t require any legal knowledge. They require a specific, written response before signing the contract. They apply regardless of the city or industry. We’ve covered a full analysis of red flags in contracts with software development companies in a separate post: What a software development company won't tell you before you sign the contract.
QUESTION 1
Who owns the copyright?
It should read: To you, upon payment of the last invoice, in all fields of use.
QUESTION 2
Where are the repositories hosted?
It should read: on your GitHub/GitLab account starting on the 1st, the agency as a collaborator.
QUESTION 3
Who exactly is working?
It should include: first name, last name, years of experience, and hours assigned per week. Not job titles.
QUESTION 4
What exactly does the SOW cover?
It should include: a list of screens, integrations, acceptance criteria, and a written procedure for scope changes.
QUESTION 5
What are the terms of termination?
It should be: 30 days' notice, transfer of code and documentation within 7 days, hourly billing.
What's important for a first-time founder
Most Kraków software house rankings assume the reader knows what they're buying. In reality, 70% of the founders who contact us are buying for the first time in their lives. For them, the “overall top 10” is a worse advisor than a random acquaintance from the industry.
Three things you should definitely do BEFORE you start comparing companies:
- Write down the scope on one A4 page. What exactly is being developed, for whom, which 3–5 features are must-haves, and what integrations are needed. Without this information, every agency will tell you, “The price is 50,000–200,000 PLN, depending on the scope,” and you won’t get any further.
- Identify your niche. Mobile? B2B configurator? Fintech? Automotive? Enterprise? The narrower the niche, the faster you’ll eliminate 80% of companies from the ranking.
- Call three former clients of the agency you’ve chosen (not the ones from the case study, but the previous ones). Ask directly: Was the budget on track? Was the SOW followed? Was the code transferred without any issues? These three phone calls will save you six months.
If your budget is limited (15,000–30,000 PLN for the first version), we recommend considering an article on realistic price ranges for apps before you start asking agencies for quotes.
What's next? Start with the scope, not the ranking
Choosing a software house shouldn't start with “top 10 Kraków” but with “what exactly am I building and in what niche”. Only then do you compare 3-5 companies that genuinely fit your niche, not 50 companies that just happen to be in Kraków.
If you’re building a B2B Product configurator, a client portal, an IoT dashboard, or sales automation, this is exactly what we do. In our opinion, it’s worth starting with a 30-minute diagnostic call, where we’ll be honest about whether we’re a good fit for your project scope. If not, we’ll recommend a competitor who is (sometimes one of the companies listed above, sometimes someone outside of Krakow).
The call is free and doesn't involve any slides. You'll walk away with three things: a clear definition of your project's niche, a list of 3–5 companies that fit that niche, and a list of questions to ask each of them.
OPTION 1 · DIAGNOSTIC CONSULTATION

Frequently asked questions about software houses in Kraków
Questions about rankings and selection
Why are Kraków software house rankings useless?
Because the ranking shows generic companies that are good at a little bit of everything. Your project is in one specific niche (mobile, fintech, automotive, B2B sales, digital transformation, enterprise legacy). In our opinion, choosing 3–5 companies in your niche is a better decision than going with the top 10 overall. Paid rankings show companies that have bought their way onto the list. Clutch shows companies that have received the most reviews overall. None of this answers the question “who will do MY project well.”
How many software houses operate in Kraków?
According to Clutch.co, over 200 software development companies are registered in Kraków. We estimate those actually active in B2B (regularly taking on new projects worth PLN 50k+) at 50-80. The rest are 1-3 person studios, freelancers with a company, and agencies that only work for existing clients. The “top 10″ ranking shows the same twenty companies in a different order on every portal. Niche specialists (10-30 people, 5+ projects a year in one area) are usually outside the overall top 10.
Questions about specialization and niches
What does "niche specialization" mean for a software house?
An agency that has completed 5+ projects in a single niche area (e.g., B2B configurators, mobile health, automotive ECUs, fintech KYC) over the past 24 months. This provides predictability: they know the industry’s edge cases, have proven architectural templates, and have already made the mistakes you’re making for the first time. The opposite is a generic “we do everything” agency—more expensive or less capable in every area, sometimes both at once.
Questions about the location and alternatives
Is it worth choosing a software house outside Kraków?
Yes, if your niche is narrow. Kraków doesn't have a strong concentration of companies in some niches (e.g. medical device software with FDA compliance), but Warsaw, Wrocław or Poznań do. In our view, location matters less than specialization. Remote meetings have been standard since 2020, so a physical presence in Kraków gives no real advantage. The exception: projects that require frequent on-site work (e.g. enterprise legacy implementations). In that case a local agency saves on travel costs.
