Website Visitor Identification
Website visitor identification tools reveal which companies, and in some markets which individual people, are browsing a site anonymously, so a sales team can follow up on interest that never filled in a form.
Most of the traffic that matters never converts on the page: a buyer reads the pricing page three times, forwards it to a colleague, and disappears. This category resolves that anonymous traffic against IP-to-company graphs, ad-network cookie pools, or opted-in identity networks, then routes the resulting signal into Slack, a CRM, or an outbound sequence. Person-level resolution is a US-centric product with real privacy trade-offs; company-level resolution is the safer default everywhere else.
