158 companies with evidence of recommendation systems work in Poland; 49 meet the ranking criteria. Sources: 158 by their Clutch profile, KRS records, available financial statements and employee reviews. If one senior engineer is enough, I build AI features with AI agents.

Best for: Startups and SMBs with a defined web, mobile or AI build that want low rates and accept a team working from Ukraine.
Verdict. Pick DBB Software for a defined web or AI build at low rates, delivered from Ukraine with a Kraków front office. Skip it if you need a team in Poland.
Pros
Net profit of 1,500,000 PLN in 2025 on 3,600,000 PLN revenue. (2026-10-28 · source)
Clutch rating of 5/5 from 34 client reviews. (2026-10-28 · source)
Best for: Anything around Atlassian, Jira, monday.com or a migration to Atlassian Cloud, and enterprise projects that need a 250+ company behind them.
Verdict. If your problem lives in Jira, Confluence or monday.com, this is the obvious call in Wrocław. For a custom product, read the case studies first and ask which team you would get.
Pros
Net profit of 30,400,000 PLN in 2025 on 407,800,000 PLN revenue. (2026-09-22 · source)

Projects & technologies
Source observations
Deviniti is the oldest and largest firm in the set. It was founded in 2004, has 330 IT experts and released its first Atlassian Marketplace app in 2012 (source).
The business centers on Atlassian, monday.com and Freshworks consulting plus its own apps, with generative AI layered on top (source).
Client counts conflict on one page, with 15,000 clients in the intro, 10,000 in the 2023 milestone and 236 organizations in the client section (source).
Many case studies are anonymized (a bank, a parcel company, a healthcare company), so only a few names can be verified (source).
Best for: Companies that need a large dedicated team fast, across many technologies, and can run it with their own product owner.
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.
Pros
Net profit of 363,200 PLN in 2025 on 177,100,000 PLN revenue. (2026-10-28 · source)

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.
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.

Service-area listings without confirmed local offices 3
A Clutch service-area listing does not establish an office. These records lack the location evidence required for this ranking. A paid placement by itself does not lower the score.

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
Ask for an A/B test result from a live store or app, not offline metrics. A recommender pays off only when it moves conversion or retention.
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.

Tell me what you are building. Within 24 hours on working days you get my own estimate and a shortlist of the best-fit agencies from this ranking with their offers, or my match if they stay silent. No commission, no obligation.
How this works: I write back with my own offer and forward your brief to the agencies that fit, after you agree. As of November 2, 2026 no agency pays me for leads and this page has no affiliate links. If that changes, it will say so here.
Questions
What are the best recommendation and personalization system companies in Poland in 2027?
By the score on this page: 1. Stratoflow (78), 2. Netguru (73), 3. JCD.PL (72), 4. DBB Software (70), 5. Deviniti (67). 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 in the data set.
How much do recommendation systems agencies in Poland 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 recommendation systems?
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 the Wrocław company 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

731with KRS records
462with a financial statement
7,436Clutch listing records
690employee review profiles on GoWork
Sources: Clutch profiles and listings, KRS records, available financial statements from rejestr.io and the Financial Documents Repository, GoWork reviews, JustJoin.it and No Fluff Jobs listings, and the Wrocław company catalog. Coverage varies by company; dates and links accompany the available records. The 0 to 100 score combines five axes: transparency, client reputation, stability, specialization and activity. Paid Clutch placements do not increase 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.
No agency pays for a position, there are no affiliate links. 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, source links and dates accompany the available company records.
Przemysław Zalewski, a senior full-stack engineer in Wrocław with 15+ years of shipping software. 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.
