Ask anyone outside Poland to name a Polish SaaS company and you will hear Booksy, DocPlanner, maybe Brand24. Three names for a market that has hundreds.
We put the rest of them in a spreadsheet.
This is a free, ungated database of more than 400 Polish B2B SaaS companies, with the region and city for each one. No form, no email required, no trial. Open it, copy it, use it.
What follows is the part most resource pages skip: what the data actually shows, what the file is missing, and how to turn a list of company names into a working outbound campaign.

What is in the file
Four columns per company: name, voivodeship (Poland's regional administrative unit), city, and a logo URL.
That is deliberately thin, and it matters that you know it upfront. The file gives you an account universe, not a contact list. No websites, no headcount, no revenue, no decision-maker names. If you want those, you add them yourself, and the enrichment section below covers how.
An account universe is still worth having. Most people building a Polish target list start by scraping LinkedIn filters that return software houses, IT consultancies, and outsourcing shops mixed together with actual product companies. Starting from a curated list of SaaS vendors saves the week you would spend cleaning that up.
Where Polish SaaS actually sits
The concentration is sharper than most people expect.
All 16 Polish voivodeships appear in the database, but two of them hold more than half the companies.
At city level: Warsaw leads with 136, Wrocław follows with 88, then Kraków at 42, Poznań at 29, and Gdańsk at 22. Those five cities cover roughly three quarters of the list. The remaining quarter is scattered across 42 other locations, and 29 of those towns have exactly one company in the file.
Two observations worth pulling out.
Wrocław punches above its weight. Kraków has the bigger tech reputation abroad, largely because of the outsourcing and shared-services industry that grew there. On product companies, Wrocław ranks second in this dataset by a wide margin. Worth noting: the Wrocław sample here is unusually deep, so treat the exact gap as directional rather than definitive.
The long tail is real. A quarter of these companies are outside the five main hubs, in places like Bielsko-Biała, Olsztyn, Koszalin, Rzeszów, and Zielona Góra. Those companies are almost never in anyone's target list, because everyone filters on the big cities. They also get contacted less, which is exactly the argument for including them.
Why the geography changes your outreach
Concentration this heavy has practical consequences.
If you sell something that benefits from meeting in person, two cities cover half your market. A two-day trip to Warsaw and a train to Wrocław puts you within reach of more than 220 of these companies. That is a very different calculation from the US, where the same coverage means crossing a continent.
Event strategy follows the same logic. Polish SaaS founders cluster around a small number of recurring meetups and conferences, most of them in Warsaw, Wrocław, and Kraków. A single well-chosen event reaches a meaningful slice of the list.
Referral density is the third effect. In a market where most product companies sit in five cities, founders know each other. One good reference travels further in Poland than it does in a fragmented market. The flip side also holds: a bad experience gets around.
Turning a company list into a contact list
The database gives you accounts. Here is how we take a file like this to a running campaign.
Step one: define who you are actually selling to. Four hundred companies is not an ICP. Cut it down using something you can defend: company size, tech stack, funding status, or the specific problem your product solves. Thirty accounts you understand beat 400 you guessed at.
Step two: resolve names to domains. The file has company names but no websites. Run the list through Clay to match each name to a domain and LinkedIn company page. Expect some manual cleanup, especially for the companies whose names in the file include taglines or descriptions.
Step three: build the contact layer. Once you have LinkedIn company URLs, pull decision-makers by role. For a Polish B2B SaaS company, the useful entry points are usually the founder or CEO, the Head of Sales, and whoever owns marketing. Most of these companies are small, so titles are broad and founders are still involved in vendor decisions.
Step four: verify before you send. Run emails through a waterfall using Prospeo, Findymail, and Apollo, then verify with a tool like Bouncer, which happens to be on this list itself. Polish domains often use catch-all configurations, so verification matters more here than in the US.
Step five: pick your language deliberately. Covered below, because it is the decision foreign vendors most often get wrong.
What foreign vendors get wrong about selling into Poland
Assuming English is fine everywhere. It usually is with founders and engineers at product companies, and this list is full of exactly those people. It is much less safe with operations, finance, or procurement contacts, and less safe again outside the main cities. If your buyer is technical, English works. If your buyer is not, a Polish-language sequence will noticeably outperform an English one.
Copying US-style copy directly. Polish B2B buyers respond poorly to the hyperbolic register that works in American outbound. Superlatives and social-proof stacking read as noise. Specificity, a clear reason for contact, and brevity work better.
Ignoring the rules on unsolicited email. Poland is stricter than the United States. Where CAN-SPAM allows cold commercial email with an opt-out, Polish law generally requires prior consent before sending commercial communication to an electronic address, and the rules changed again with the Electronic Communications Law that took effect in 2025. On top of that, GDPR applies to how you source and store the data. Get a Polish lawyer to review your process before you send at volume. This article is not legal advice, and the penalty for guessing wrong is real.
Pricing without adjusting. Polish companies at this stage buy carefully and negotiate on annual commitments. Sticker prices set for US mid-market will stall deals that would close at a localized number.
Who else this list is useful for
Sales teams are the obvious audience, but the file works for several other jobs.
Recruiters use it to map where product engineering roles exist outside the outsourcing sector. Investors and corp-dev teams use it as a starting universe for sourcing in a market that has no good public directory. Partnership teams use it to find integration candidates. And Polish SaaS founders themselves use it for competitive research, since a lot of these companies have never crossed each other's radar.
If you run any of those functions, the enrichment steps above apply the same way. The bottleneck is never the company names.
Four ways to waste this file
Emailing all 400. The list is a universe, not a segment. Blasting it produces a bad reply rate, a damaged sending domain, and no learning about which segment actually converts.
Skipping verification. A file this size does not survive a high bounce rate. One bad send can take a warmed domain out of the inbox for weeks.
Treating every company as the same size. The database mixes companies with three people and companies with three hundred. Your message has to change accordingly, and nothing in the file tells you which is which until you enrich it.
Writing in English by default. Test both. On most Polish campaigns we run, the language decision moves reply rates more than any other single variable in the sequence.
FAQ
Is the database free? Yes. No gate, no form, no email. Open the sheet and make a copy.
How many companies does it include? More than 400 rows covering Polish B2B SaaS vendors across all 16 voivodeships. The file contains a small number of duplicate entries where a company appears under two spellings, so clean it before you import.
What data does each row contain? Company name, voivodeship, city, and a logo URL. No contact data, no revenue, no headcount.
Where does the data come from? Public company records and business data sources, compiled by the Vanderbuild team. Treat it as a research starting point rather than a verified CRM import.
Can I send cold email to these companies? Polish rules on unsolicited commercial email are stricter than US rules and generally require prior consent, with GDPR governing how you handle the data. Check your specific approach with a Polish lawyer before running a campaign at volume.
Should I write in Polish or English? Depends on the buyer. Technical founders and engineering leaders at these companies read English comfortably. Commercial, finance, and operations contacts often do not, particularly outside Warsaw, Wrocław, Kraków, Poznań, and Gdańsk. When in doubt, test both.
How often is it updated? Periodically. Company names and locations change, so verify anything you plan to build a campaign around.
Do you have a version with contact data? Not publicly. We build enriched, ICP-filtered lists for clients as part of campaign setup.
What to take away
Warsaw and Wrocław hold more than half the Polish B2B SaaS market between them, and five cities cover roughly three quarters of it. That concentration makes in-person selling, event strategy, and referral plays unusually efficient here compared to larger markets.
The quarter of companies sitting outside those hubs is the part most people never contact, which is a reasonable argument for starting there.
The file itself is four columns. Everything that makes it valuable happens after you enrich it, segment it, and decide what language to write in.
We do that work for clients across Polish and international markets. If you want the campaign built rather than the spreadsheet downloaded, book a free consultation.
