🇵🇱Poland Business Database — Verified B2B Leads Across All Voivodeships (2026)

20 min read

Why a Poland Business Database Is Essential for B2B Growth in 2026

Poland is the largest economy in Central and Eastern Europe and one of the fastest-growing B2B markets in the European Union. With approximately 2.5 million active businesses, a GDP exceeding €650 billion, and a deeply diversified economy spanning IT and software development, automotive manufacturing, agriculture, fintech, BPO/shared services, and retail, Poland represents one of the most significant opportunities for B2B sales and marketing teams targeting the CEE region. Warsaw alone is home to the regional headquarters of hundreds of multinational corporations, and thriving business hubs in Kraków, Wrocław, Poznań, Gdańsk, and Łódź continue to attract international investment at record rates.

But reaching Polish businesses effectively requires more than ambition. You need accurate, verified contact data. You need to know who the decision-makers are, what their email addresses are, whether those emails actually work, and what industry and company size you are dealing with. Manually building lists from KRS (the National Court Register) or CEIDG takes weeks and produces inconsistent results. Generic purchased lists are riddled with outdated contacts, invalid emails, and missing data fields. The difference between teams that consistently fill their pipeline and teams that struggle is almost always the quality of their lead data.

That is exactly what a high-quality Poland business database solves. In this comprehensive guide, we cover everything you need to know about Polish business databases in 2026 — what data fields are included, how WholeDatabase collects and verifies Polish company data, coverage across all 16 voivodeships, how to use these leads for GDPR-compliant outreach, and how WholeDatabase compares to alternatives like ZoomInfo, Apollo, and Hunter. Whether you are a startup founder in Warsaw or a sales director managing a team targeting the Polish market, this guide will help you make a smarter data investment.

What Is a Poland Business Database?

A Poland business database is a structured, searchable collection of company and contact information for businesses operating across all 16 voivodeships of Poland. It goes far beyond what you would find in a basic directory like Panorama Firm or PKT. Instead of just a company name and phone number, a modern B2B database includes verified email addresses, direct-dial phone numbers, decision-maker names and job titles, registered company addresses, PKD codes (the Polish Classification of Business Activities system), employee counts, estimated revenue, and KRS or CEIDG registration numbers.

Unlike consumer databases that focus on individuals, a B2B business database is built around companies and the people who make purchasing decisions within them. Every record represents a real, actively trading business entity — whether it is a spółka z ograniczoną odpowiedzialnością (sp. z o.o.), a spółka akcyjna (S.A.), a sole proprietorship (działalność gospodarcza), or a partnership. The best databases update their records daily, removing dissolved companies, correcting outdated contact information, and adding newly registered businesses as they appear in KRS and CEIDG.

Who Uses a Poland Business Database?

The primary users are sales development representatives (SDRs) and account executives who need a steady flow of fresh leads to fill their pipeline. But the use cases extend well beyond outbound sales. Marketing teams use Polish business databases to build targeted advertising audiences and account-based marketing (ABM) lists. Recruitment agencies use them to identify growing companies and connect with hiring managers. Digital agencies use them to find potential clients by industry and region. Private equity firms and venture capital funds use them for market mapping and deal sourcing in the CEE region. Even government agencies and EU institutions use business data for economic analysis and programme evaluation.

In short, if your work involves reaching out to Polish businesses — whether to sell to them, partner with them, or serve them — a Poland business database is the foundation of your workflow. The question is not whether you need one. It is which one gives you the best data at the best price, while keeping you GDPR compliant.

What Data Fields Are Included in the WholeDatabase Poland Database?

One of the most common frustrations with cheap Polish business lists is that they only provide a company name and a generic biuro@ or info@ email address. That is virtually useless for targeted outreach. To run effective B2B campaigns, you need rich, multi-dimensional data that lets you personalise your messaging and precisely target the right accounts and decision-makers.

WholeDatabase provides 18+ data fields for every Polish business record. Each field is collected from public sources and verified through our AI pipeline. Here is the complete breakdown of what you get with every lead:

ℹ️Multi-Step Email Verification

Every email address in the WholeDatabase Poland database goes through a 4-step verification process: syntax validation, domain existence check, MX record verification, and SMTP mailbox confirmation. This is why our verified email deliverability rate exceeds 95% — significantly higher than industry averages of 70-80%. You will see fewer bounces, protect your sender reputation, and get more replies from Polish prospects.

Having all 18+ fields in a single export means you do not need to juggle multiple tools or manually enrich your data. Download a CSV, import it into your CRM or email platform, and you are ready to launch campaigns immediately. Every field is filterable in the WholeDatabase app, so you can narrow your list to exactly the segment you need — for example, "Director or C-level contacts at IT companies in Warsaw with 50-500 employees."

How WholeDatabase Collects and Verifies Polish B2B Data

Data quality is everything. A database with millions of records is worthless if half the emails bounce and the company information is two years out of date. That is why WholeDatabase built a fully automated, AI-powered data collection and verification pipeline that runs 24/7. Here is how it works for the Polish market specifically:

Our system continuously scans thousands of public data sources across Poland and beyond. The primary sources are KRS (Krajowy Rejestr Sądowy), the National Court Register that holds records on all Polish companies, partnerships, and associations, and CEIDG, the Central Register and Information on Business Activity for sole proprietorships. We also scan GUS (Statistics Poland) data, professional directories, industry association membership lists, company websites, job postings on Pracuj.pl and Indeed Poland, press releases, and publicly available social media profiles on LinkedIn and GoldenLine. We do not scrape private databases or purchase data from questionable brokers. Every data point comes from a publicly accessible source, ensuring full compliance with GDPR and the Polish Personal Data Protection Act.

Your Dashboard

1
Source Discovery
Our AI agents continuously crawl KRS (Poland's National Court Register with records on all companies and associations), CEIDG (the register for sole proprietorships with 2.5M+ entries), GUS statistical data, professional directories, industry associations like BCC and ABSL, and corporate websites. We monitor new company registrations daily — approximately 1,200 new businesses are registered in Poland every working day, and our system picks them up within 48 hours.
2
Data Extraction
Raw data is extracted and structured into standardised records. Company names, registered addresses, phone numbers, email addresses, employee counts, revenue estimates, PKD codes (Poland's Classification of Business Activities), and contact information are parsed and normalised. Natural language processing identifies decision-maker names and job titles from public profiles, company websites, and KRS filings.
3
Cross-Source Enrichment
Each record is cross-referenced against multiple independent sources. If a company appears in KRS, on its own website, and in a professional directory, we merge the data to create the most complete profile possible. We reconcile company trading names with their legal registered names, match subsidiary businesses to parent companies, and resolve conflicting information using recency and source reliability scoring.
4
Multi-Step Email Verification
Every email address undergoes our 4-step verification: syntax check (valid format), domain validation (domain exists and accepts mail), MX record check (mail exchange records configured), and SMTP verification (mailbox exists and is deliverable). Polish-specific email patterns like .pl, .com.pl, and .waw.pl domains are handled with specialised validation rules. Catch-all domains and disposable emails are flagged separately.
5
Daily Delivery to Your Dashboard
Approximately 7,000 fresh, verified business leads across all countries are added to the WholeDatabase platform every single day. The Poland portion includes newly registered companies, updated contact details for existing businesses, and re-verified records. Old records are continuously re-checked, and any that fail verification are removed or flagged.

This end-to-end pipeline is what separates WholeDatabase from providers that buy bulk data lists from KRS and resell them without verification. Our data is collected first-party, verified in real-time, and refreshed daily. The result: a 95%+ email deliverability rate that protects your sender reputation and maximises your outreach ROI in the Polish market.

Polish Business Data by Voivodeship — Coverage Breakdown

WholeDatabase covers all 16 voivodeships of Poland. However, business density varies dramatically by region. Masovia (Mazowieckie), home to Warsaw, accounts for roughly 620,000 active businesses — the highest concentration in Poland. Silesia (Śląskie), Greater Poland (Wielkopolskie), and Lesser Poland (Małopolskie) are the next most business-dense voivodeships, reflecting Poland's economic geography and the concentration of industry and services.

Understanding regional business distribution is critical for effective outreach. If you are selling IT services, Warsaw and Kraków are your primary targets, but Wrocław (a major BPO and tech hub) and the Tri-City (Gdańsk, Gdynia, Sopot) are equally important. If you are targeting manufacturing businesses, Silesia, Greater Poland, and Łódź have the highest concentrations. The automotive sector clusters around Silesia, Lower Silesia, and Greater Poland, with major plants from Volkswagen, Opel, and Fiat.

PRO TIP

In the WholeDatabase app, you can filter Polish leads by voivodeship, city, or postal code prefix. If you are running a regional sales campaign — say, targeting IT companies in the "Polish Tech Triangle" of Warsaw-Kraków-Wrocław — simply select those cities, choose relevant PKD codes (62.01.Z for software development, 62.02.Z for IT consultancy), and export your list. You will have thousands of verified leads in seconds.

Industries Covered in Our Poland Business Database

The WholeDatabase Poland database covers every major industry vertical, classified by PKD codes (Polska Klasyfikacja Działalności). The PKD system, maintained by GUS (Statistics Poland), is the official framework for categorising businesses by their primary economic activity and is aligned with the EU NACE classification. Our database covers 500+ individual PKD codes grouped into the major industry verticals below.

Poland's economy has a distinctive industry mix. The IT and software sector has been growing at double-digit rates, with Poland now home to over 300,000 software developers — one of the largest talent pools in Europe. The automotive sector is a pillar of Polish manufacturing, with major plants from Volkswagen (Poznań), Mercedes (Jawor), Toyota (Wałbrzych), and Opel (Gliwice). The BPO/shared services sector employs over 400,000 people, making Poland the top nearshoring destination in Europe. Agriculture remains significant, with Poland being the EU's largest producer of apples and one of the top producers of poultry and dairy.

With new verified leads added every month, you will never run out of fresh Polish prospects — no matter how niche your target market is. Use our advanced filters to drill down by PKD code, industry keyword, company size, revenue range, and geography for laser-targeted prospecting across all 16 voivodeships.

How to Use Polish Business Leads for Sales Outreach

Having access to thousands of verified Polish business leads is powerful, but data alone does not close deals. The magic happens when you combine high-quality lead data with smart, compliant outreach strategies. Crucially, selling to Polish businesses means operating under GDPR and Polish national data protection laws overseen by UODO (the Polish Data Protection Authority) — one of the strictest regulatory environments in the EU. Here is how to use WholeDatabase leads effectively and legally.

Cold Email Campaigns (B2B GDPR Framework)

Cold email to Polish businesses is possible under GDPR when done correctly. The key legal basis is "legitimate interest" — Article 6(1)(f) of the GDPR. Under this provision, you can contact business professionals at their work email addresses if your outreach is relevant to their professional role, you have a legitimate business reason for contacting them, and you provide an easy way to opt out. Poland's Telecommunications Act (Prawo telekomunikacyjne) also requires consent for electronic marketing communications, so targeting corporate email addresses (company domains) rather than personal addresses is critical for compliance.

Best practices for cold email with WholeDatabase Poland leads: segment your list by industry and company size so you can write relevant messaging for each segment. Personalise the first line using the company name, city, or industry. Keep your email under 120 words. Include one clear call-to-action (usually a meeting request). Send 3-5 follow-ups spaced 3-4 days apart. Always include your company name, registered address, and an unsubscribe link. Use a tool like Instantly, Smartlead, or Woodpecker (a Polish cold email platform) to manage sending and follow-ups at scale.

⚠️GDPR & Polish Data Protection Compliance

When sending commercial emails to Polish businesses, you must comply with GDPR and Poland's national data protection laws. Key requirements: include your company identity and registered address in every email, provide a clear unsubscribe mechanism, honour opt-out requests promptly, target corporate email addresses rather than personal ones, and conduct a legitimate interest assessment (LIA) before starting your campaign. WholeDatabase provides B2B data from public sources under legitimate interest, but it is your responsibility to ensure your outreach complies with all applicable laws. UODO (Urząd Ochrony Danych Osobowych) can impose GDPR fines up to €20 million or 4% of global turnover.

LinkedIn + Email Multi-Channel Outreach

The highest-performing sales teams targeting Polish businesses in 2026 combine email outreach with LinkedIn touchpoints. Poland has over 5 million LinkedIn users, with particularly high penetration among IT, finance, and management professionals. Here is how it works with WholeDatabase leads:

First, export your target list from WholeDatabase with contact names and company details. Use the contact name to find their LinkedIn profile. Start your sequence with a LinkedIn connection request — a simple, non-salesy message works best. Two days later, send your first email. If they have not replied by day five, send a LinkedIn message referencing your email. Continue alternating channels for 2-3 weeks. Teams using this multi-channel approach consistently report 3-4x higher response rates compared to email-only outreach.

CRM Enrichment and Data Hygiene

Your CRM is only as valuable as the data inside it. Most B2B teams have thousands of contacts in their CRM — but a significant percentage of those records are outdated, incomplete, or have invalid email addresses. This is especially problematic in the Polish market, where approximately 30,000 companies are dissolved or struck off each year. WholeDatabase solves this by letting you export fresh, verified data as CSV and import it directly into your CRM.

Use WholeDatabase to enrich existing CRM records with missing phone numbers, updated job titles, and current company information. You can also use it to fill gaps in your total addressable market (TAM) — identify Polish companies in your target segment that are not yet in your CRM and add them.

1
Filter leads by industry, voivodeship, and company size
Log in to app.wholedatabase.com and use the advanced filters to build your target list. Select the industry (PKD codes or keywords), geographic area (voivodeship, city, or postal code prefix), employee count range, and revenue range. You can also filter by job title to target specific decision-makers like Dyrektor Zarządzający (Managing Director), Head of Marketing, or IT Director.
2
Export CSV with verified emails and phone numbers
Once your list is filtered, click Export to download a clean CSV file. Pro plan users get unlimited CSV exports with full contact details — verified emails, direct phone numbers, company addresses, and all 18+ data fields. The CSV is formatted for easy import into any CRM or email platform.
3
Import into your CRM or email outreach tool
Upload the CSV to Salesforce, HubSpot, Pipedrive, or your cold email tool (Instantly, Smartlead, Woodpecker, etc.). Map the columns to the corresponding fields in your system. Most tools auto-detect common field names like 'Email', 'Company', and 'Phone'.
4
Launch your targeted, GDPR-compliant outreach campaign
With your leads loaded, create personalised email sequences segmented by industry and company size. Use the data fields to personalise: reference the company name, city, industry, or employee count in your messaging. Include your company name, registered address, and unsubscribe link in every email. Monitor open rates, reply rates, and bounce rates. With WholeDatabase data, expect bounce rates under 2% and deliverability above 95%.

WholeDatabase vs Other Polish Lead Providers

There are several B2B data providers that cover the Polish market, and choosing the right one can make or break your outreach budget. We have done the comparison so you do not have to. Below is an honest, feature-by-feature breakdown of WholeDatabase against the three most popular alternatives: Apollo.io, ZoomInfo, and Hunter.io.

The Polish B2B data landscape has some unique characteristics. ZoomInfo has limited Polish coverage and focuses primarily on enterprise accounts at enterprise pricing — starting at $14,995 per year. Apollo.io has been growing its European data but still has significant gaps in Poland outside Warsaw. Hunter.io is popular for email finding but is not a full business database — you cannot browse by PKD code, voivodeship, or company size. Polish-specific providers like Bisnode Poland, Panorama Firm, and CRIBIS offer company data but typically lack verified email addresses and daily refresh rates.

Let us break this down with real numbers. If you need 200,000 verified Polish leads per month (which is what WholeDatabase Pro gives you for $49), here is what that would cost on competing platforms:

  • Apollo.io: Their Professional plan gives you limited export per month. To get anywhere near 200K contacts, you would need their highest tier at $99/mo+ and still face export caps. Their Polish data coverage outside Warsaw is notably thin. Real cost for equivalent volume: $500+/month.
  • ZoomInfo: Their SalesOS platform starts at $14,995 per year (roughly $1,250/month) with seat-based pricing and credit limits. ZoomInfo has very limited Polish coverage, focusing primarily on enterprise multinationals.
  • Hunter.io:Their Business plan at $99/month gives you 10,000 searches and 10,000 verifications. You would need 20x that volume to match WholeDatabase. Hunter also does not provide company data — only email addresses.

The Value Math

WholeDatabase delivers 200,000 verified leads for $49/month — covering Poland and dozens of other countries. The same volume on Apollo would cost $500+/month, and on ZoomInfo, $14,995+ per year. For Poland-focused teams, WholeDatabase offers the best combination of data quality, coverage, and affordability.

Data Quality and Verification Process

A database is only as good as its verification process. Sending emails to unverified addresses damages your sender reputation, wastes your time, and can get your domain blacklisted. In the Polish market, where .pl domains and Microsoft 365 / Google Workspace email hosting are extremely common, verification accuracy is particularly important because both providers have strict bounce handling policies.

Our verification system processes millions of email addresses daily using a four-step approach. Each step filters out a different category of bad addresses, and only emails that pass all four steps are marked as "Verified" in the database. Here is what each step does:

4-Step Process

Email Verification Pipeline

Step 1: Syntax Check

98% pass

Validates email format — catches typos like jan@@firma.pl or missing TLDs

Step 2: Domain Validation

97% pass

Confirms the domain exists, is active, and resolves correctly via DNS lookup

Step 3: MX Record Check

96% pass

Verifies mail exchange records are properly configured to receive email

Step 4: SMTP Verification

95%+ pass

Connects to the mail server and confirms the specific mailbox exists and is deliverable

Result: 95%+ Deliverable Emails

Only verified, deliverable emails make it into your dashboard

Beyond the four-step verification, we also perform catch-all detection. Some Polish mail servers are configured to accept email to any address at their domain (e.g., [email protected] will be received). These catch-all domains make it impossible to verify individual mailboxes via SMTP. We flag these as "Catch-all" in the database so you can make an informed decision about whether to include them in your campaigns.

We also filter out disposable email addresses and role-based addresses(biuro@, info@, sekretariat@, recepcja@) unless they are the only available contact for a company. The Polish market has a higher prevalence of "biuro@" and "sekretariat@" addresses than Western European markets, so our Poland-specific rules handle these appropriately.

Pricing — Get 200,000 Polish Leads for $49/month

WholeDatabase was built with a simple pricing philosophy: give B2B teams the maximum amount of verified data at a price that any company can afford. We do not believe in €12,000/year contracts, per-seat pricing, or credit systems that force you to ration your prospecting. See our full pricing page for details, or read on for a summary of our three plans:

Free Plan — Test the Waters

Our free plan gives you access to 1,000 Polish business leads per month with masked contact details (partial email and phone). This is designed for you to explore the data quality, test the filters, and see for yourself that our records are accurate and up-to-date. No credit card required — just sign up and start browsing.

Pro Plan — $49/month — Best Value

The Pro plan is where the real power is. For $49 per month (approximately PLN 200), you get access to 200,000 verified business leads with full, unmasked contact details — emails, phone numbers, addresses, and all 18+ data fields. You get unlimited CSV exports, advanced filters, and approximately 7,000 fresh leads added to your dashboard every day across all countries. Data accumulation means your total available leads grow month over month. Cancel anytime — no annual contracts.

Enterprise Plan — Custom Pricing

For large teams with specialised needs, our Enterprise plan includes everything in Pro plus API access, custom data pipelines, dedicated account management, priority support, and SLA guarantees. We can also provide custom Data Processing Agreements (DPAs) for GDPR compliance. Contact our sales team to discuss your requirements.

Data compliance is not optional in Poland — it is rigorously enforced by UODO (Urząd Ochrony Danych Osobowych), Poland's national data protection authority. UODO has been actively issuing fines under GDPR, including several high-profile penalties against Polish companies. WholeDatabase takes Polish data compliance extremely seriously. Here is how we ensure that our Poland business database meets the highest standards.

GDPR & Polish Personal Data Protection Act

Poland implements GDPR through the Polish Personal Data Protection Act (Ustawa o ochronie danych osobowych) of 2018. WholeDatabase processes all Polish B2B data under a legitimate interest basis (Article 6(1)(f) of GDPR). We have conducted a thorough Legitimate Interest Assessment (LIA) that confirms: there is a genuine business need for B2B contact data, the processing is necessary to meet that need, and the rights and freedoms of data subjects are not overridden. We collect only publicly available business information and honour all data subject access requests (DSARs) and deletion requests within the mandated 30-day timeframe.

Polish Telecommunications Act

The Prawo telekomunikacyjne (Telecommunications Act) regulates electronic marketing communications in Poland. Article 172 requires consent for direct marketing via electronic means. For B2B communications, targeting corporate email addresses at company domains — rather than personal email addresses — is the standard approach. WholeDatabase focuses exclusively on B2B corporate email addresses to support compliant outreach.

Our Data Sources Are 100% Public

Every data point in the WholeDatabase Poland database comes from publicly accessible sources: KRS (National Court Register) filings, CEIDG registrations, GUS statistical data, company websites, professional directories, job boards, and public LinkedIn profiles. We do not purchase data from third-party brokers of unknown origin. We do not scrape private databases. We do not use hacked or leaked data.

ℹ️Data Removal Process

If any individual or company wishes to be removed from the WholeDatabase, they can submit a request through our website or by emailing our data protection team. All removal requests are processed within 72 hours — well within the GDPR's 30-day requirement. You can also contact us directly. We maintain a permanent suppression list to ensure removed records are never re-added. For more details, visit our GDPR policy page and our Acceptable Use Policy.

KEY TAKEAWAY

WholeDatabase is fully compliant with GDPR and the Polish Personal Data Protection Act. All data is B2B only, collected exclusively from publicly available sources, and verified through our automated pipeline. We honour all data removal requests within 72 hours and maintain a permanent suppression list. We recommend consulting with a Polish legal advisor regarding Prawo telekomunikacyjne compliance before launching cold email campaigns in Poland.

Frequently Asked Questions About Our Poland Business Database

How many Polish business leads does WholeDatabase have?

WholeDatabase currently tracks approximately 2.5 million Polish businesses across all 16 voivodeships. Pro plan subscribers can access up to 200,000 verified leads per month, with approximately 7,000 new leads added to the platform every day across all countries. The total database grows continuously as our AI pipeline discovers and verifies new businesses from KRS, CEIDG, corporate websites, and professional directories.

How often is the Poland business database updated?

The database is updated daily. Our automated pipeline runs 24/7, adding fresh, verified leads each day while simultaneously re-verifying existing records. Companies that have been dissolved, contacts that have changed roles, and email addresses that are no longer deliverable are flagged or removed. We also monitor KRS and CEIDG for new registrations — approximately 1,200 new Polish businesses are registered every working day.

Does WholeDatabase cover all 16 voivodeships?

Yes. WholeDatabase covers all 16 Polish voivodeships comprehensively. Masovia has the highest business density (approximately 620,000 businesses), followed by Silesia (350,000+), Greater Poland (310,000+), Lesser Poland (280,000+), and Lower Silesia (250,000+). You can filter by voivodeship, city, or postal code prefix in the app.

Are the email addresses verified?

Yes. Every email address undergoes our 4-step verification process: syntax validation, domain existence check, MX record verification, and SMTP mailbox confirmation. Only addresses that pass all four steps are marked as "Verified." Our overall deliverability rate exceeds 95%. Polish-specific email patterns (.pl, .com.pl domains) are handled with specialised validation rules.

Is it legal to send cold emails to Polish businesses?

Cold B2B email in Poland is governed by GDPR and the Polish Telecommunications Act. Under GDPR, B2B cold email can be justified under the "legitimate interest" basis (Article 6(1)(f)). The Telecommunications Act requires consent for electronic marketing, so targeting corporate email addresses at company domains is the recommended approach. We recommend consulting with a Polish legal advisor before launching large-scale campaigns.

Can I filter leads by voivodeship, city, or industry?

Absolutely. The WholeDatabase app includes advanced geographic filters for voivodeship, city, and postal code prefix. You can select multiple regions at once or drill down to a specific city. Combine geographic filters with industry and company size filters for precision targeting.

Is there a free trial?

Yes. WholeDatabase offers a free plan that gives you access to 1,000 business leads per month with masked contact details. This is not a time-limited trial — it is a permanent free tier. No credit card is required. When you are ready for full access, upgrade to Pro for $49/month.

How does WholeDatabase compare to Polish-specific data providers?

Polish-specific providers like Bisnode Poland, Panorama Firm, and CRIBIS offer good company-level data (KRS records, financial data, credit scores), but they typically lack verified email addresses for individual decision-makers and do not provide daily data refresh. WholeDatabase fills a different niche: verified B2B contact data for sales and marketing outreach, updated daily, at a fraction of the price.

Is the data GDPR compliant?

Yes. WholeDatabase collects only B2B data from publicly available sources (KRS, CEIDG, company websites, public filings, professional directories). We process data under a legitimate interest basis for B2B communications, which is compliant with GDPR and the Polish Personal Data Protection Act. We honour all data subject access requests (DSARs) and deletion requests within the mandated timeframes.

What is included in the $49/month Pro plan?

The Pro plan includes access to 200,000 verified business leads per month with full, unmasked contact details (verified emails, direct phone numbers, company addresses) across Poland and dozens of other countries. You also get unlimited CSV exports, advanced filters (industry, voivodeship, city, PKD code, company size, revenue, job title), approximately 7,000 fresh leads added daily, and data accumulation. There are no annual contracts — you can cancel anytime.
