How to choose

What to look at

Privacy & hosting: for EU traffic, prefer EU-hosted, company-level tools that avoid storing PII.

Pricing model: watch for prices that climb steeply with volume or opaque annual quotes. A free plan lets you compare on your own traffic.

Fit, not hype: person-level tools (mostly US) and enterprise ABM suites solve different problems. Match the tool to your market and team.

How to read this

How we built this comparison

Every figure here comes from each vendor's own pricing page, checked directly — not from third-party aggregators. Where a vendor doesn't publish pricing, we say 'on request' rather than guess. We never invent competitor data.

The honest takeaway: the tools differ most on three axes — where your data is hosted, whether they store PII, and how the price scales with volume. For EU B2B, EU-hosted is usually the safer default; person-level US tools solve a different problem.

FAQ

Questions, answered.

Which tool is best for EU B2B traffic?

Prefer EU-hosted, company-level tools that avoid storing PII. That's the lane Nalloo is built for.

Which is the cheapest at the same volume?

At comparable company volumes, the EU company-level tools cluster between roughly €70 and €330/month for ~1,000 companies; Nalloo sits at the low end. Compare each on your own traffic with a free trial.

Does Nalloo identify individual people?

No. Nalloo identifies companies, not people. It never stores personally identifiable information.

Is Nalloo GDPR-compliant?

Yes. Nalloo identifies companies (not natural persons), stores no personal data; IP addresses are processed hashed, inside the EU. This page is informational and not legal advice.
