The 6 Best B2B Data Providers in Finland: One Bureau, One Open API (2026)

Finland runs a genuinely useful free layer and a genuinely dominant paid one, side by side. The Business Information System, YTJ, jointly operated by the patent office and the tax administration, gives free basic company data and even digital financial statements through an open API. What it deliberately leaves out is contact detail: no phone numbers, no email addresses. So the register tells you a business exists and how it is doing, but not how to reach it.

On top of that free base sits Suomen Asiakastieto, the bureau that has effectively been the Finnish credit market for over a century and is now part of the listed Enento group that also owns Sweden's UC. Around it are the rebranded former Bisnode, a well-known Finnish sales-data disruptor, and the directory and media-backed players. This guide sorts out who adds what.

It ranks {count} providers on merit. We sell Finnish business data ourselves, so our pitch sits in a marked box rather than at number one.

In a hurry? The short answer

1. Suomen Asiakastieto: the dominant bureau

The bureau that is effectively the Finnish credit market, and the default for any credit decision.

Tracing back to a Tampere credit-information agency in 1905, Suomen Asiakastieto is the dominant Finnish credit bureau: business and consumer credit data, payment-default entries, scores and limits, financials, decision-maker and marketing data, and monitoring. Since 2018 it has been part of the listed Enento group, which also owns Sweden's UC. For a Finnish credit decision it is the reference, and its payment-default data is the first thing lenders check.

3. Dun & Bradstreet Finland: the incumbent rival

The main alternative to Asiakastieto on business data, backed by the global D&B file.

Rebranded from Bisnode Finland in early 2022, after D&B completed its acquisition of the Bisnode group, this is the main rival to Asiakastieto: business information, credit and risk scores, company master data, analytics and the D-U-N-S number with global coverage. It is the natural choice when Finnish data needs to sit inside a worldwide risk or master-data picture, and a credible second opinion on domestic credit.

4. Vainu: the Finnish disruptor

The homegrown sales-intelligence platform, built on open company data, though smaller than at its peak.

Founded in Helsinki in 2013, Vainu built an AI-driven sales-intelligence platform on open company data: firmographics, financials, group structure, decision-maker contacts, technographics and trigger events, with CRM connectors for prospecting and data maintenance. It is Finland's best-known company-data tech story, and still independent, though it has contracted from its peak scale. For prospecting and keeping a CRM current, it is the local, modern option.

5. Fonecta: the directory

The directory and marketing-data house, right for B2B lists and local search rather than risk.

Fonecta, with roots in the Finnish directory business and founded in its current form in 2002, provides business directory and contact data through fonecta.fi and Finder, plus B2B marketing data and digital-presence services. It expanded across the Nordics by acquiring Norway's 1881 group. For Finnish B2B marketing lists, local business search and digital marketing it is a natural pick, but it is a marketing-data house, not a credit or register source.

6. Alma Talent: the media-backed data

Sales intelligence and financial data with a business-media pedigree behind it.

Alma Talent, part of the listed Alma Media group, sells business and decision-maker data, company financials, real-estate and legal content, with the financial-media weight of Kauppalehti and Arvopaperi behind it. It sits between a sales-intelligence tool and a research service, aimed at finance and sales teams that want data and editorial context together. Not a bureau, but a credible Finnish source for company research and prospecting.

How Finland's market took shape

Finland pairs an old dominant bureau with a modern open register, and recent moves reshaped both ends:

So who is still actually Finnish?

The dominant bureau is now part of a listed Nordic group, while the prospecting and media players stay Finnish:

Free data, minus the contacts

Finland's YTJ is a genuinely useful free layer. Jointly run by the patent office and the tax administration, it publishes basic company data and digital financial statements through a free open API, updated daily. The deliberate gap is contact detail: phone numbers and email addresses are not in the open dataset, and some entity types such as private traders are excluded. So the register tells you a business exists and how it is doing, but not how to reach it.

That gap is exactly where the commercial layer earns its place. Asiakastieto adds credit scoring and payment-default data, D&B adds global reach, Vainu and Fonecta add contacts and prospecting signals. The financials are free; the scoring, the contacts and the workflow are not. Check the free source here:

• YTJ : The Business Information System: free basic company data and status, jointly run by the patent office and the tax administration.
• PRH open data : The patent office open-data API, including digital financial statements, free to use.
• Suomi.fi : The national service portal that also exposes the Business Information System for verification.

Four questions before you sign anything

1. Do you need contacts the register omits? YTJ gives you facts and financials free but no phone numbers or emails. If you need to reach the business, that is precisely what you are buying from a provider, not the registration data itself.

2. Credit, or prospecting? For credit decisions and payment-default data, Asiakastieto is the default and D&B the rival. For prospecting and CRM data, Vainu, Fonecta and Alma Talent are the fit. Do not buy a credit bureau for a marketing job.

3. Do you want a genuine second opinion? Asiakastieto dominates, so pairing it with D&B gives you an independent read on the same businesses rather than one source twice.

4. Are the free financials enough? PRH publishes digital financial statements for free. If you only need the numbers rather than a score or a contact, you can build on the open API before paying anyone.
