What is Nalloo?

Nalloo is a B2B website visitor identification tool. It reveals the real companies behind your anonymous traffic — by company name, domain and on-site intent — without storing personal data. EU-hosted, GDPR-friendly, one line of code.

The transformation

Your traffic is already talking.
You're just not listening.

Most websites identify 0% of their B2B traffic. Nalloo identifies the companies — by name.

Why company-level

Why company-level identification wins for B2B

For B2B, the buying unit is the company, not the individual. A single deal can involve five or six people across weeks of research — most of whom never fill out a form. Knowing that Acme visited your pricing page three times this week tells your team where to focus far better than a list of anonymous sessions.

Company-level identification is also the privacy-safe foundation: because Nalloo resolves the organisation behind an IP — never a named person — it works without storing personal data. You get the intent signal that drives pipeline, and your legal team gets a clean answer.

FAQ

Questions, answered.

Can I run Nalloo alongside Google Analytics?

Yes. Nalloo doesn't replace web analytics — it adds the missing B2B layer (which companies, not just how many sessions). Keep GA for behaviour and add Nalloo for named accounts.

How is this different from buying a contact list?

A purchased list is cold and static. Nalloo shows companies that are actively on your site right now, with the pages they viewed as live intent — warm, timely and tied to your own traffic.

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.

How many companies will I see?

Typically 8–18% of B2B traffic depending on industry and market. Corporate networks resolve best; mobile and consumer ISPs less. Start free and see your own rate.

Does it work with my CRM?

Yes — native one-click OAuth for HubSpot, Salesforce and Pipedrive.

Will it slow down my website?

No. The tracker is ~4 KB, loaded async and deferred; it never blocks rendering.

You're ~10 seconds from your first lead.
