Dutch Company Data for Lead Generation
Search the Dutch business registry by industry, location, and legal form. Build targeted prospect lists with verified company data, contact addresses, and VAT numbers.
Finding and qualifying Dutch leads takes too long
Breaking into the Dutch market requires accurate company data. You need to identify businesses in specific industries, verify they are active, and collect their contact details. But the Dutch business landscape has its own classification system (SBI codes), its own registry (KVK), and its own legal structures.
Generic business databases often have outdated or incomplete Dutch company records. Company names are misspelled, addresses are wrong, and there is no reliable way to filter by industry or legal form. Your sales team wastes hours cleaning data instead of reaching out to prospects.
Scraping public directories or buying third-party lists gives you quantity but not quality. What you need is direct access to the official Dutch business registry, with the ability to search, filter, and export verified company profiles.
Search, filter, and enrich Dutch business leads
The KVKBase API lets you search the Dutch business registry by company name, location, industry (SBI code), or legal form. Every result includes the full company profile: legal name, trade names, registered address, VAT number, and industry classification.
Combine search with enrichment to build a complete pipeline. First, search for companies matching your ideal customer profile. Then enrich each result with detailed company data for qualification and outreach.

print(f"Found {len(leads)} qualified leads")The search endpoint supports multiple filters that you can combine. Search by SBI code to target specific industries, filter by city or province for geographic targeting, and narrow by legal form to focus on BVs, NVs, or sole proprietorships depending on your ideal customer profile.
