Nalloo

Nalloo is a B2B website visitor identification service that connects anonymous traffic to companies, not individual people. It suits teams qualifying target accounts from site activity and routing those signals into a CRM. Choose it for company-level context and EU-focused privacy controls; look elsewhere if you need named contacts.

Overview

Nalloo identifies a visiting company by name and domain, with on-site intent and visitor activity history to help teams judge which accounts merit follow-up. Firmographic details can include industry, company size, headquarters, founding year and technology hints from public sources. This gives sales and marketing teams useful account context, but it does not reveal contact details or turn an anonymous visit into a person-level lead.

Nalloo says it stores no personal profiles or PII for visitor identification and hashes visitor IPs inside the EU. Its DPA describes hosting in Frankfurt and Madrid, encryption in transit and at rest, access controls, activity logging, monitoring, and backup and recovery procedures. The product is made by Ecofin Cloud S.L., based in Sant Cugat del Vallès, Barcelona, Spain.

Key features

• Company identification and reverse IP lookup: Nalloo links website activity to companies rather than individuals. That is a good fit for account-based prospecting, but not for teams that need a visitor's name, email address or other contact information.
• CRM connections: One-click OAuth integrations with HubSpot, Salesforce and Pipedrive provide a direct path for moving company signals into existing workflows. Starter and higher plans include CRM sync; teams that need this handoff should budget for a paid subscription.
• Optional inbox scanner: An IMAP scanner can identify and enrich companies that have emailed the customer. It extends company-level context to incoming email, but is optional rather than part of the free or pay-as-you-go offer.
• Branded campaign links: Nalloo's nll.me short links include company-level click attribution, giving campaigns another way to connect engagement to organizations.
• Lightweight installation: The asynchronous JavaScript tracker is about 13 KB and does not block page rendering. Installation instructions cover WordPress, Shopify, Webflow, Google Tag Manager and plain HTML, which should make deployment practical across common site setups.
• Usage billing: Only new company identifications at medium or higher confidence count. Repeat companies in the same month and low-confidence, bot, VPN or Tor results are free, so the quota is less wasteful than a raw count of every visit. Once the allowance is spent, new identifications pause unless pay-as-you-go is enabled; that setting is off by default.

Pricing

Nalloo has a free entry point and paid usage and subscription plans. There is no free trial, so the free plan is the way to assess the product before committing.

• Free — €0 forever: 50 identifications per month, full dashboard and firmographics, community support and no credit card. It is a sensible starting point for low-volume evaluation, but the cap can constrain ongoing prospecting.
• Pay as you go — €0.20 per token: No monthly fee or commitment, and it includes everything in Free. This is the flexible choice for irregular identification needs; unlike a subscription, it provides no stated monthly token allowance.
• Starter — €75 per month: Includes 500 tokens, with extra tokens at €0.18 each, plus CRM sync, inbox scanner and email support. It suits teams that need these workflows and a modest recurring volume, but overages still add cost.
• Scale — €500 per month: Includes 5,000 tokens, with extra tokens at €0.10 each, everything in Starter and priority support. The lower overage rate and larger allowance fit higher-volume teams; it is a substantial step up in monthly spend.
• Enterprise — custom pricing: Unlimited volume, a dedicated EU instance, custom contract and DPA, onboarding and dedicated support. This is aimed at organizations needing a tailored deployment and support arrangement rather than a standard allowance.

Free includes community support, Starter email support, Scale priority support and Enterprise dedicated support. Because pay-as-you-go is off by default, teams relying on uninterrupted identification should enable it or monitor their allowance.

Platforms

Nalloo is available on web and through an API. Its JavaScript tracker can be installed on WordPress, Shopify, Webflow, Google Tag Manager or a plain HTML site. The small asynchronous script avoids blocking page rendering, making it a relatively light addition to a website.

Who it's for

Nalloo is best for B2B marketing and sales teams that already attract relevant website traffic and want to prioritize companies by firmographic context and intent. It is particularly useful when CRM handoff or company-level campaign attribution matters. It is a poor fit for contact discovery, person-level visitor identification, or teams that need every new identification to continue automatically without enabling pay-as-you-go.

Pros and cons

• Pro: Company identification is paired with firmographics and activity history, helping teams evaluate accounts rather than merely count traffic.
• Pro: Usage billing excludes repeat monthly companies and low-confidence, bot, VPN or Tor results, reducing charges for results less likely to be useful.
• Pro: CRM integrations, inbox enrichment and branded attribution links connect identification to several practical B2B workflows.
• Pro: The stated EU data handling and security controls may suit organizations seeking EU-hosted infrastructure and company-level identification without stored personal profiles.
• Con: Nalloo does not reveal individual contact details, so teams seeking named leads need a separate source.
• Con: Free is limited to 50 identifications per month, and new identifications stop at the cap unless pay-as-you-go is enabled.
• Con: CRM sync and the inbox scanner begin with Starter at €75 per month, putting those workflows beyond the free and usage-only tiers.

Verdict

Nalloo is a strong fit for B2B teams that want to turn anonymous site activity into company-level account signals, especially when EU-oriented privacy controls and CRM handoff are priorities. Its best reason to choose is the combination of firmographics, intent and flexible usage billing; its clearest reason to look elsewhere is that it never identifies individual contacts. Start with Free for modest volume, use pay-as-you-go for irregular needs, and choose a subscription when CRM workflows or sustained throughput justify the monthly cost.
