The 13 Best B2B Data Providers in the Netherlands: Life After the KVK (2026)

Since September 2024 the Dutch Chamber of Commerce hides entrepreneurs' phone numbers by default. Sole traders can shield their address. The free open datasets ship without names, without KVK numbers, without full postcodes. The register that used to be the country's prospecting goldmine has been quietly closing its doors for six years, and that single fact explains this entire market: what you are shopping for is no longer the register, it is the layer somebody built on top of it.

This guide ranks 12 Dutch providers on merit, from the register heavyweights to the web crawlers and the shared-file collective. We sell Dutch business data ourselves, so our pitch sits in a clearly marked box further down instead of at number one. Start with the cheat sheet.

2. Company.info: the register heavyweight

The most complete Dutch business file, and the one with the shortest path to the register itself.

Founded in 1998 and owned by FD Mediagroep (the publisher behind Het Financieele Dagblad and BNR) since 2012, Company.info is an official KVK service provider, which means real-time access to Handelsregister mutations rather than a monthly refresh. On top of that it stacks annual accounts, creditworthiness, shareholder structures, UBO data, Kadaster property records, RDW vehicle data and news from 1,500+ sources, across 2.5M businesses and 2.5M business people. It absorbed marketing-intelligence firm Sizo in 2018. If one vendor has to cover KYC, credit and sales at once, this is usually the answer.

3. GraydonCreditsafe: credit risk at volume

The default for Dutch credit decisions at portfolio scale, with payment behaviour data few can match.

Graydon has been scoring Dutch businesses since roughly 1888. Creditsafe completed its acquisition from Atradius in March 2022, and the joint brand now pairs Graydon's Dutch depth with a group serving 120,000 customers worldwide. You get credit scores and limits, payment behaviour, annual accounts, register data and compliance screening, plus international reports on the same contract. Graydon was also one of the five founders of the VVZBI, the trade association that took KVK to court and won.

4. Altares Dun & Bradstreet: for D-U-N-S thinkers

The Benelux gateway into the global D&B file, strongest when your suppliers and customers span continents.

Altares is the exclusive Dun & Bradstreet partner for the Benelux and France, not a D&B subsidiary; the group is majority-held by French investor Naxicap. It brings D-U-N-S numbering, 130M+ business records across 240+ countries, failure scores, compliance data and master-data management. It bought Dutch master-data specialist Olbico in 2019 and Belgian favourite Companyweb in January 2025. Note there is no separate D&B Netherlands to compare it against; in this market Altares is the D&B route.

5. DATA-collectief: the shared file

The only Dutch provider where customers actively improve the file, and you can join without giving anything back.

Running since 2005, DATA-collectief built something genuinely different: a shared file fed by KVK and the insolvency register, then continuously corrected by the organisations that use it. Participants connect their own address file, it gets matched and cleaned against the collective, and their corrections flow back in, roughly 450,000 to 550,000 mutations a month. Contributing is optional, so you can benefit without opening your own data, and no personal data moves between participants. Undeliverable post loops back into the file too. They also run an outsourced appointment-setting service, which makes them part data vendor, part sales agency.

6. Ad Hoc Data: the transparent one

The only provider on this page that publishes its price list, and it is refreshingly cheap.

Ad Hoc Data has been selling Dutch address files since 2004 and covers 3.4M+ organisations, plus Belgium. What sets it apart is honesty about money: €0.08 per record one-off, €0.12 with building filters, subscriptions from €55 a month, API tiers from €100. Selection runs on 130+ criteria including some nobody else offers, like energy consumption and building type. There is also a KVK API product positioned as an enriched alternative to the official one. No credit scores, no compliance layer; this is a list-building tool that respects your time.

7. NextBI: the quiet veteran

A 1947 lineage and 3.6M records including the institutions most files forget.

The company traces back to 1947, traded as Schober Nederland, became DR3Data when it split from the German Schober group in 2012, was bought by De Telefoongids in 2016, and went independent again through a management buyout by Jaap Wolff in 2018. Since 2022 it is NextBI. The file holds 3.6M+ Dutch organisations, and unusually it includes government bodies, institutions, foundations and associations, the segments most commercial files thin out. Address files, APIs, a business finder and custom BI work; pricing is quote-based.

8. Bedrijfsdata.nl: what firms actually run

Register data tells you a business exists; this tells you which software it runs.

The company was formally incorporated recently, but the data asset goes back to the late 1990s, built by technical director Peter Schinkel. The angle is web and technographic enrichment: it crawls 1.3M+ Dutch business websites and derives software and app usage, ad networks, e-commerce platforms and social signals. You can buy ready-made datasets (everyone using a given platform, say), build a custom set, or hit the API. Its sister product handles website visitor identification. For a software vendor hunting firms on a competing platform, this beats any register file.

9. CreditDevice: software plus its own file

The rare vendor that owns both the credit management software and the data feeding it.

CreditDevice positions itself as the only Dutch party combining self-built credit management software with its own business information file, refreshed daily against roughly 10,000 sources and enriched with property, vehicle fleet and website signals. Its reports are accepted for self-assessment by credit insurers Allianz Trade, Atradius and Coface, which is a meaningful third-party endorsement. It is a VVZBI member and also operates in Germany. Smaller than GraydonCreditsafe, and that is sometimes the point.

10. Dataprovider.com: the whole web, indexed

Not a register vendor at all: 400M+ domains a month, and Dutch coverage falls out of that.

Founded in Groningen in 2012 and still fully bootstrapped with no outside investors, Dataprovider.com indexes over 400 million domains every month across 200+ fields: technology detected, classification, engagement and risk signals. Customers include PayPal, GoDaddy and national statistics offices, which tells you the accuracy bar. Delivery is via a search interface, a REST API, or warehouse shares in Snowflake, BigQuery and Databricks. Use it for brand protection, payment risk and technographic targeting, not for annual accounts.

11. REACH (Moody's, formerly Bureau van Dijk): the analyst's tool

Structured Dutch financials and ownership trees, built for people who model rather than prospect.

REACH is the Dutch national product in the Orbis family, from Bureau van Dijk, which Moody's acquired in 2017 for €3bn. It offers deep structured financials, ownership structures and directors with screening and peer-group tools, and connects into Orbis for cross-border research. Dutch universities subscribe to it, which says exactly who it is for: analysts, researchers and transfer-pricing teams rather than sales or credit controllers.

12. Leadinfo: who visited your site

A different question entirely: not which firms exist, but which ones just looked at you.

Leadinfo identifies the businesses behind anonymous website traffic and pushes them into your CRM, with 70+ integrations and 9,000+ European customers. Part of team.blue since 2022, it bought Swiss competitor LeadRebel and Canadian Visitor Queue in 2025, so the consolidation is running its way. It only surfaces firms already on your site, which makes it a complement to a data file rather than a replacement, and a strong one if your marketing already pulls traffic.

13. Datlinq: every kitchen in the country

Niche by design: if you sell to foodservice or food retail, generic files will not do.

Datlinq maps foodservice and food retail locations: restaurants, cafés, hotels, canteens and supermarkets, with the operator detail and location intelligence that generic business files flatten into a single activity code. Acquired by Amsterdam-based Roamler in 2021, the brand and its CEO stayed in place. For food, beverage and hospitality suppliers this is the market map; for anyone else it is irrelevant, which is exactly how a niche provider should look.

How the Dutch register quietly closed its doors

The single most important thing to understand about this market is not who owns which vendor. It is that the free source everyone once relied on has been shrinking for six years, on purpose. The timeline:

So who is still actually Dutch?

The Dutch market held on to its independents better than Belgium did. If local ownership matters for procurement or principle, this is the 2026 picture:

What the official sources still give you for free

The Handelsregister remains the backbone of every Dutch business file, but the free routes into it are narrower than most people assume. The open dataset covers only BVs and NVs and deliberately omits the KVK number, the organisation name, the full postcode and every sole trader. The annual accounts dataset strips personal data. The paid KVK API is the practical route for public data, at a couple of cents per profile, while the heavyweight Dataservice carries a four-figure connection fee and a two-month setup.

That gap is the entire business case for the providers above. Check the primary sources yourself here:

• KVK Handelsregister : The official register. Free open dataset for BV and NV basics, paid API for the fields that matter.
• Centraal Insolventieregister : Bankruptcies, suspensions of payment and debt restructuring, updated daily by the courts.
• CBS Statistics Netherlands : Aggregate business statistics from the national statistical business register, free as open data.

Four questions before you sign anything

1. Register access or own research? Some providers are official KVK service providers with real-time mutations. Others build their own picture from the web, from members, or from fieldwork. Neither is better in the abstract, but as the register closes further, own-research files get relatively more valuable.

2. Which fields survived the shielding? Phone numbers have been hidden by default since September 2024 and sole-trader addresses can be shielded. Ask specifically how a provider fills those gaps today, and when their mobile and email fields were last verified.

3. One job or five? Credit checks, compliance, prospecting, technographics and visitor identification are five different products. The Dutch market has genuine specialists in each. Buying one tool for all five usually means overpaying for four.

4. Can they show a GDPR paper trail? Register facts about legal entities are public, but director names, mobile numbers and personal email addresses are personal data needing a legal basis and a working opt-out. Ask for provenance per field before anything reaches your CRM.
