Best European Sales Intelligence

Looking for a GDPR-compliant alternative to ZoomInfo, Apollo.io or Clearbit? European sales intelligence tools find and enrich the B2B contact and company data a sales team prospects from, whether by identifying companies already visiting your website or by searching a contact database, while keeping the data itself under EU jurisdiction.

How we rank these tools — 4-step process
  1. 1
    European ownership, verified

    The company is headquartered and incorporated in the EU, EEA or Switzerland, and processes customer data in Europe. A US parent company disqualifies a tool from this page regardless of where its servers are.

  2. 2
    Category fit and hands-on review

    What the tool actually does, who it suits, and where it falls short — checked against the vendor’s own documentation, changelog and pricing page rather than its marketing copy.

  3. 3
    Compliance and pricing check

    GDPR posture, hosting location and the prices quoted on this page are verified against the vendor’s public pricing before publication, and re-checked when we revisit the category.

  4. 4
    Position on this page

    Placement on this page can be paid, and that can affect the order tools appear in. It never buys a listing: a tool that fails the checks above is not here at any price, and payment does not change the shortcomings we write about. A vendor can ask us to correct a factual error — not to remove a criticism.

Vendors can pay for visibility on this page. It never changes what an entry says about a product, including the criticism, and we earn nothing when you click through to a vendor. Paid placement can affect the order in which tools appear; it never affects whether a tool is listed. Editorial policy

How we review

Key takeaways

  • Leadfeeder ranks #1 among European sales intelligence tools because it is the only one with a genuine, permanent free tier alongside published pricing on every paid plan.
  • Three of the five — Leadfeeder, Leadinfo and SalesViewer — work by identifying companies already visiting your website, not by searching a pre-built outbound database like ZoomInfo or Apollo.io.
  • Vainu is the deliberate outlier: Nordic-only coverage, deeper than any pan-European tool, but useless for prospecting outside Denmark, Finland, Norway or Sweden.
  • Overloop is the only tool here that pairs contact data with outbound multichannel sequencing, though it prices in USD despite its Belgian incorporation.
  • Four of the five publish real pricing; only Vainu is quote-only.

Looking for a GDPR-compliant alternative to ZoomInfo, Apollo.io or Clearbit? European sales intelligence tools find and enrich the B2B contact and company data a sales team prospects from, whether by identifying companies already visiting your website or by searching a contact database, while keeping the data itself under EU jurisdiction.

Every European sales intelligence tool reviewed

#1 Leadfeeder

Karlsruhe, Germany (office in Helsinki, Finland) 2022 merger; Leadfeeder brand dates to 2012 Free Lite tier; paid plans from €79/month

Best for: A company that wants to start reading its website traffic for free and only pay once it needs verified contact details, intent signals or CRM automation

  • Operating company. Dealfront Group GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. EU data hosting, GDPR-compliant
  • Source code. Closed source
  • Replaces. ZoomInfo, Apollo.io, Clearbit

Leadfeeder is the current brand name for what was, from 2022 to 2025, marketed as Dealfront — formed when Echobot, a German B2B data company, merged with Leadfeeder, a Finnish website-visitor-identification company, backed by a €180 million investment from US private equity firm Great Hill Partners. The legal entity remains Dealfront Group GmbH, a German GmbH with offices in Karlsruhe and Helsinki; the company moved the whole platform back under the better-known Leadfeeder name in 2025.

The free Lite plan is genuinely permanent — unlimited users, up to 100 identified companies a month, 7-day visitor history — before paid tiers from Discover (€79/month) through Activate and Scale add verified contacts, intent filtering and CRM automation.

What Leadfeeder does well

  • Genuine always-free Lite tier, not a time-limited trial
  • German GmbH entity with EU data hosting
  • Website-visitor identification catches active buying interest a cold-search database cannot show

Where Leadfeeder falls short

  • Verified contact emails and phone numbers are reserved for Activate and above
  • The 2022 merger was funded by a US private equity firm, though the legal entity stays German

Standout feature. A real, permanent free plan rather than a disguised trial.

#2 Leadinfo

Capelle aan den IJssel, Netherlands Founded not stated by the vendor From €69/month (annual), published tiers

Best for: A team wanting a straightforward Dutch visitor-ID tool with published pricing and no permanent free tier to worry about outgrowing

  • Operating company. Leadinfo (part of teamblue)
  • Jurisdiction. EU (Netherlands)
  • Where the data sits. EU data hosting, GDPR-compliant, ISO 27001 certified
  • Source code. Closed source
  • Replaces. ZoomInfo, Apollo.io, Clearbit

Leadinfo, based near Rotterdam, decodes anonymous website traffic into named visiting companies and layers on a 300 million-plus contact database, real-time alerts and CRM integrations. It is part of teamblue, a Dutch/Belgian software group, and holds ISO 27001 certification. Pricing starts from €69 a month billed annually, with a 14-day free trial and no credit card required to start — but no permanent free tier once the trial ends.

What Leadinfo does well

  • Published pricing from €69/month, no sales call needed to see a number
  • ISO 27001 certified, backed by an established Dutch software group
  • 14-day trial with no credit card required

Where Leadinfo falls short

  • No permanent free tier, unlike Leadfeeder
  • Founding year not published, making the company's track record harder to assess

Standout feature. A no-credit-card 14-day trial that makes evaluating the product genuinely frictionless.

#3 Vainu

Helsinki, Finland Founded 2013 From roughly €3,500/year, quoted

Best for: A sales or marketing team selling into Denmark, Finland, Norway or Sweden that needs local-language, locally-sourced data a pan-European database does not cover as deeply

  • Operating company. Vainu.io Oy
  • Jurisdiction. EU (Finland)
  • Where the data sits. EU data hosting, GDPR-compliant
  • Source code. Closed source
  • Replaces. ZoomInfo, Apollo.io, Cognism

Vainu takes a narrower bet than most tools in this category: rather than chasing global coverage, it goes deep on the four Nordic markets, pulling from local business registries, news, job postings and filings in each country's own language. Vainu.io Oy has built the product since 2013. Pricing is not published as a self-serve rate card; it starts from roughly €3,500 a year and is quoted after a sales conversation.

What Vainu does well

  • Deep, local-language data coverage across all four Nordic markets
  • One of the more established vendors in this category, operating since 2013
  • Intent signals drawn from local sources rather than generic firmographic data

Where Vainu falls short

  • No published pricing; every deal starts with a sales conversation
  • Coverage is deliberately Nordic-only, the wrong tool outside those four markets

Standout feature. Local-language data depth across all four Nordic markets, sourced from each country's own registries rather than translated from a pan-European dataset.

#4 Overloop

Brussels, Belgium Founded 2015, as Prospect.io From $69/user/month, published tiers

Best for: A team that wants a contact database and outbound multichannel sequencing in one product rather than two separate tools

  • Operating company. Overloop SRL
  • Jurisdiction. EU (Belgium)
  • Where the data sits. EU data hosting, GDPR-compliant
  • Source code. Closed source
  • Replaces. Outreach, Apollo.io, Salesloft

Overloop, rebranded from Prospect.io after Brussels-based Sortlist acquired it in 2022, pairs a 450 million-plus contact database with outbound sequencing across email and LinkedIn — closer to a sales-engagement tool with data built in than a pure lookup database.

It is the only tool in this category that combines both jobs in one product. Pricing is published from $69 per user per month, though quoted in USD despite the Belgian entity, a detail worth noting when budgeting in euros. There is no permanent free tier, but a 7-day trial is available.

What Overloop does well

  • Combines a large contact database with outbound sequencing in one product
  • Belgian entity under GDPR, with published pricing
  • 450M+ contact database, competitive with dedicated lookup tools

Where Overloop falls short

  • Priced in USD despite EU incorporation
  • No permanent free tier, only a 7-day trial

Standout feature. The only tool in this category that bundles contact-data lookup with outbound multichannel sequencing, rather than requiring a separate sales-engagement tool.

#5 SalesViewer

Bochum, Germany Founded 2010 From €99/month

Best for: A marketing or sales team that wants to know which companies are already visiting its website, at an accessible entry price

  • Operating company. SalesViewer GmbH
  • Jurisdiction. EU (Germany)
  • Where the data sits. EU data hosting, GDPR-compliant
  • Source code. Closed source
  • Replaces. ZoomInfo, Apollo.io, Clearbit

SalesViewer, built by SalesViewer GmbH in Bochum since 2010, is one of the longer-running vendors in this category. Like Leadinfo and Leadfeeder, it works by decoding anonymous website traffic back into named visiting companies rather than searching a pre-built contact database, then layers on behavioural tracking, lead scoring and CRM integrations. Plans start from €99 a month and scale with identified-visitor volume; there is no published free tier, and evaluating the product means booking a demo.

What SalesViewer does well

  • Accessible entry price at €99/month for this category
  • German company under GDPR, with EU data hosting
  • One of the more established vendors, operating since 2010

Where SalesViewer falls short

  • No published free tier; evaluating the product means booking a demo
  • Identifies only companies already visiting your website, nothing for outbound prospecting

Standout feature. An accessible €99/month entry point into website-visitor identification from a vendor that has run the same core product since 2010.

Visitor identification or a contact database?

Three of these five tools — Leadfeeder, Leadinfo and SalesViewer — answer the question "who is already looking at our website?" by decoding anonymous IP traffic back into named companies. Vainu and Overloop are closer to the traditional model: a searchable database you query from a standing start, by job title, industry or region.

Neither approach is strictly better; they answer different questions, and larger sales teams often run one of each rather than treating them as substitutes.

Frequently Asked Questions

Leadfeeder ranks #1 in this directory because it is the only tool in the category with a genuine, permanent free tier alongside published pricing on every paid plan. The right answer still depends on the job: Leadinfo for a straightforward Dutch visitor-ID tool, Vainu for deep Nordic-only data no pan-European database matches, Overloop for outbound multichannel sequencing on top of contact data, and SalesViewer for the most accessible entry price.

All five tools in this category are built as European alternatives to ZoomInfo, Apollo.io and Clearbit. Three of them — Leadfeeder, Leadinfo and SalesViewer — work by identifying companies already visiting your website rather than searching a pre-built outbound database, which is a genuinely different workflow worth understanding before switching. Vainu and Overloop are closer to the outbound-database model, with Vainu focused specifically on the Nordics.

Leadfeeder starts with a genuinely free Lite plan and moves to paid plans from €79/month. Leadinfo starts from €69/month, SalesViewer from €99/month, and Overloop from $69/user/month, all with published tiers. Vainu is the outlier: pricing starts from roughly €3,500 a year and is quoted rather than published as a self-serve rate card.

Leadfeeder is the only tool here with a genuine, permanent free tier — unlimited users and up to 100 identified companies a month, not a time-limited trial. Leadinfo, Overloop and SalesViewer all offer free trials instead of a permanent free plan; Vainu has no free tier or trial stated.

Website-visitor identification — used by Leadfeeder, Leadinfo and SalesViewer — decodes anonymous traffic on your own website back into named visiting companies, telling you who is already showing interest. A contact database, closer to how Vainu and Overloop work, is searched from a standing start by job title, industry or company size to find people who have not necessarily shown any interest yet. They answer different questions and often get used together rather than as substitutes.

Vainu, built specifically around Denmark, Finland, Norway and Sweden, pulling from each country's own business registries, news and job postings in the local language — coverage a pan-European or US-built database typically cannot match in depth, though it comes at the cost of being useless outside those four markets.
