Nalloo

Nalloo identifies companies behind anonymous B2B website traffic, showing company name, domain, and on-site intent. Company details can include industry, size, headquarters, founding year, and technology hints from public sources. One-click OAuth integrations connect with HubSpot, Salesforce, and Pipedrive. An optional IMAP inbox scanner can find companies that have emailed the customer and enrich them in the same way. Branded nll.me short links provide company-level click attribution. Nalloo says it identifies companies rather than individuals, stores no personal profiles or PII for visitor identification, and hashes visitor IPs inside the EU. The JavaScript tracker is about 13 KB and loads asynchronously. Installation instructions cover WordPress, Shopify, Webflow, Google Tag Manager, and plain HTML. The free plan includes 50 identifications per month, a dashboard, firmographics, and community support. Pay-as-you-go is €0.20 per token with no monthly fee; Starter costs €75 per month and Scale €500 per month. Only qualifying new identifications count toward usage. When an allowance runs out, new identifications pause unless pay-as-you-go is enabled, which is off by default.

Nalloo focuses on company-level identification and enrichment, with CRM connections and an optional inbox scanner. The free plan has a monthly allowance, and new identification pauses at the cap unless pay-as-you-go is switched on.

Nalloo may suit B2B teams looking to identify organizations visiting their website and connect those results to a CRM. Its free plan offers a starting option, while paid tiers add usage and support provisions.

Nalloo is built for B2B teams that need to turn anonymous website visits into company-level account signals. It suits marketers and sales operations focused on firmographic qualification, campaign attribution and CRM handoff rather than finding individual contacts. The main trade-off is clear: useful enrichment and integrations, but no person-level identities and a relatively small free allowance.

Overview

Nalloo identifies the company behind a visit using company name, domain and on-site intent. Identified accounts may include industry, company size, headquarters, founding year and technology hints drawn from public sources. Visitor activity history and reverse IP lookup support account research, while contact details remain outside the product’s scope. That makes Nalloo appropriate for deciding which accounts merit follow-up, not for turning a visit into a named lead.

Its privacy posture follows the same company-level boundary. Nalloo says it stores no personal profiles or personally identifiable information for visitor identification and hashes visitor IPs inside the EU. The DPA describes EU hosting in Frankfurt and Madrid, encryption in transit and at rest, access controls, activity logging, monitoring, and backup and recovery procedures. The service is operated by Ecofin Cloud S.L. in Sant Cugat del Vallès, Barcelona, Spain.

Key features

• Company identification and firmographics: Account names, domains, intent and public-source firmographics give revenue teams context around existing traffic. The absence of contact details means teams still need another system for person-level prospecting.
• CRM connections: One-click OAuth integrations with HubSpot, Salesforce and Pipedrive reduce the friction of moving account signals into established workflows. This is most valuable when sales follow-up already happens in one of those CRMs.
• Optional inbox scanner: An IMAP scanner finds companies that have emailed the customer and enriches them in the same way as website visitors. It extends coverage beyond web traffic, but remains company enrichment rather than contact discovery.
• Campaign attribution: Branded nll.me short links include company-level click attribution, giving campaign teams an account view of link engagement instead of individual clicker identities.
• Lightweight installation: The approximately 13 KB JavaScript tracker loads asynchronously, so it does not block page rendering. Installation guidance covers WordPress, Shopify, Webflow, Google Tag Manager and plain HTML, making deployment practical across common site setups.
• Usage accounting: Only new identifications at medium or higher confidence consume allowance. Repeat companies in the same month, low-confidence results and bot, VPN or Tor traffic are free. When an allowance is exhausted, new-company identification stops unless pay-as-you-go is enabled; that safeguard is off by default.

Pricing

Nalloo uses a freemium model, with paid usage from €0.20 per token and no free trial.

• Free — €0 forever: 50 identifications per month, the full dashboard and firmographics, community support and no credit card. It is a sensible way to evaluate account-level identification, but the cap is restrictive for an active marketing site.
• Pay as you go — €0.20 per token: No monthly fee or commitment, with everything in Free and payment per company. This fits irregular traffic or teams that want to exceed 50 identifications without taking on a subscription; costs become less predictable as volume rises.
• Starter — €75 per month: Includes 500 tokens, then €0.18 per extra token, plus CRM sync, inbox scanner and email support. It is the practical step for a small revenue team that needs integrations and a defined monthly allowance.
• 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 favors sustained, higher-volume account identification, but the subscription only makes sense when usage approaches that level.
• Enterprise — custom pricing: Unlimited volume, a dedicated EU instance, custom contract and DPA, onboarding and dedicated support. It targets organizations requiring contractual and deployment customization rather than a standard self-serve plan.

Platforms

Nalloo is offered through a web interface and API. Its asynchronous tracker can be added through the supported site builders or plain HTML, while CRM connections use OAuth.

Who it's for

Nalloo is best for B2B marketing, sales and revenue-operations teams that already generate website or email traffic and want account-level prioritization, firmographic context and CRM delivery. It is also a good fit for privacy-conscious organizations that want company signals without storing visitor profiles or PII. Look elsewhere if your workflow depends on identifying individual people, revealing contact details or maintaining large volumes on a small budget.

Pros and cons

Pros

• Company, domain and intent signals are supplemented by useful firmographics for account qualification.
• HubSpot, Salesforce and Pipedrive OAuth connections, plus the inbox scanner, support direct operational handoff.
• EU hashing and hosting, documented controls and a non-blocking tracker address privacy and implementation concerns.
• Pay-as-you-go avoids a recurring fee for uneven demand.

Cons

• The Free plan allows only 50 identifications per month, so regular prospecting quickly reaches its ceiling.
• No contact details or person-level identification are provided.
• Starter and Scale require meaningful monthly commitments, while pay-as-you-go can become expensive at high volume.
• Identification pauses at the allowance unless pay-as-you-go is deliberately switched on.

Alternatives

Leadfeeder is the better choice when a free plan with up to 100 identified companies per month, seven days of history and unlimited users matters more than Nalloo’s firmographic and inbox options. Choose Leadberry if a free trial is important. RB2B suits teams wanting Slack delivery and 150 monthly resolutions on its free plan, while Visitor is aimed at a smaller starting footprint with 25 lifetime identified companies. Warmly is an alternative for API/MCP workflows with credit-based plans. ConnectLoop Visitor Intelligence, TAPNET Visitor Identification and Factors.ai are other options to compare when their respective delivery models or plan structures fit better.

Verdict

Choose Nalloo if your priority is privacy-conscious, company-level visitor intelligence that can flow into a mainstream CRM, with optional email enrichment and campaign attribution. Its strongest advantage is the combination of firmographics, integrations and flexible usage billing. Look elsewhere if you need named contacts, person-level resolution or a larger free quota before committing to paid volume.
