Website visitor identification for B2B SaaS.

PLG & self-serve

From anonymous evaluation to a named account

Most product-led SaaS funnels are top-heavy with research traffic that never fills in a form. A buyer at a target account reads your homepage, clicks through to pricing, opens the docs to gauge implementation effort, then closes the tab to discuss it internally. By the time anyone signs up for a free trial, the real evaluation is already days old. Nalloo closes that blind spot by resolving the company behind those sessions from network signals — the visitor's ASN and corporate reverse-DNS — so a self-serve motion no longer means a silent one. You see which companies are circling pricing and product pages well before a trial request lands.

This matters because intent in SaaS is rarely a single event. A genuine evaluation looks like three pricing visits across a week, a docs deep-dive, and a return trip to a comparison page. Each of those is a company-level signal Nalloo captures without storing personal data. Because identification runs on hashed IP addresses inside the EU rather than device fingerprints, you build a picture of account intent that holds up to a privacy review — useful when your own buyers are themselves security-conscious software teams. The result is a shortlist of accounts that are already evaluating you, ranked by how much of your funnel they have actually touched.

Nalloo's confidence score keeps that shortlist honest. Every identification is graded very_high, high, medium, low or none, and you are only billed on medium and above — low-confidence guesses, bots, VPN and Tor traffic are shown but never charged, and seeing the same company twice in a month is free. For a SaaS team running paid acquisition into a self-serve funnel, that means you can act on the strong signals and ignore the noise without inflating your cost per identified account.

The workflow

How a SaaS team puts it to work

Identification only matters if it reaches the people who can act on it. Nalloo is built so a lean SaaS team can route account intent into the tools it already lives in, without a data-engineering project.

• ✓ Push warm accounts to your CRM. Native one-click OAuth for HubSpot, Salesforce and Pipedrive sends identified companies straight into the pipeline, so an AE picks up an evaluating account instead of a cold list.
• ✓ Qualify with built-in firmographics. Industry, company size, HQ, founded year, LinkedIn and tech-stack hints come from public sources, so you judge fit before anyone spends a minute on outreach.
• ✓ Track campaigns with branded nll.me links. Share a launch or comparison asset behind a short link and see company-level click attribution — which accounts your demand campaigns actually pulled in.
• ✓ Catch inbound email interest. The optional inbox scanner connects over IMAP to surface companies that emailed you, closing the loop between sales conversations and on-site behaviour.
• ✓ Start without a sales call. The free plan gives you 50 identifications a month with no credit card, and pay-as-you-go is off by default — no surprise invoice while you prove the signal on your own traffic.

The SaaS funnel

Catch demand before the form

In B2B SaaS, the highest-intent visitors often slip away unconverted: they read your pricing, open the docs, start a comparison — then leave without a trial. Nalloo surfaces those companies so your team can reach the ones already evaluating you.

Pair it with your CRM and you can route warm accounts to sales the moment intent spikes, and attribute campaigns to the companies they actually brought in.
