B2B Lead Generation Company in Europe and UK

Callbox has been running lead generation in Europe since 2004. With a dedicated UK office, multilingual SDR teams, and campaigns covering the UK, DACH, Nordics, Benelux, and Southern Europe.

For US and North American companies, we remove the three biggest barriers to European market entry: local know-how, regulatory compliance (GDPR), and the time and cost of building an in-house European sales team.

Our Human + AI approach consistently delivers 30% more appointments and 25% faster sales cycles.

GDPR compliance is built into every stage of our European campaigns - from how we source and maintain prospect data, to how we structure outreach sequences and handle opt-outs.

We operate under EU data protection standards across all member states, and our legal and data teams ensure that your outreach is fully compliant with both GDPR and ePrivacy regulations. This protects your brand and ensures long-term, scalable outreach without regulatory exposure.

We run lead generation service in the EU and across the wider European region, including the UK & Ireland, Germany, Austria, Switzerland (DACH), the Netherlands, Belgium, the Nordics (Sweden, Norway, Denmark, Finland), France, Spain, and Italy.

Whether you're targeting a single market or launching a pan-European campaign, we can build and execute the right strategy.

Yes. As a dedicated UK lead generation agency, Callbox has a London office and a team with deep expertise in the UK B2B landscape.

We run targeted outreach to UK decision-makers across enterprise and mid-market sectors, including Financial Services,

Technology, SaaS, Manufacturing, and Healthcare — all fully compliant with UK GDPR (post-Brexit data regulations).

Absolutely. Our multilingual teams conduct outreach in English, German, French, Dutch, and other European languages.

This goes beyond translation — our SDRs are trained to communicate in alignment with the business norms and buyer expectations of each target market, producing significantly better engagement than templated, translated outreach.

Pricing is customized based on your target European markets, campaign scope, and lead volume goals.
We offer flexible subscription-based programs.

You can do either. We have an in-house data research and enrichment team that builds and maintains verified B2B databases across industries.

If you already have a list, we can clean, validate, and enrich it. If not, we’ll create one from scratch that aligns with your ICP and region—ensuring accurate and compliant outreach under GDPR, CCPA, PDPA, and CAN-SPAM standards.

Our clients typically see a 30% increase in appointment rates and 25% faster sales funnel movement after working with Callbox.

Results depend on your industry, audience, and message alignment, but every campaign is monitored and optimized through our AI analytics and team feedback loops to ensure continuous improvement.

Most lead generation companies in the EU are built for European companies selling to European buyers. Callbox is specifically experienced in helping North American B2B companies enter and scale across European markets — bridging the gap between US-style sales culture and European buyer expectations.

We combine 20 years of global experience, a dedicated European presence, an AI-powered platform, and a subscription-based model that scales with your growth — with no guesswork and full transparency.
