What Lead Forensics does
Lead Forensics is a UK-founded, privately held B2B sales-intelligence platform that identifies the companies behind anonymous visits to a customer's website by matching visitor IP addresses against a proprietary, in-house-built B2B IP database maintained over 17 years. The platform enriches these identified companies with firmographic data, behavioral intent signals, and decision-maker contact details (phone, email, LinkedIn), then routes them into sales workflows through native integrations with Salesforce, HubSpot, Microsoft Dynamics 365, Pipedrive, and Zoho, or via Zapier for downstream tool coverage. The company sells two software subscription tiers (Essentials and Automate) priced on a quote-based, traffic-dependent, annual basis with unlimited user seats, supplemented by a three-tier agency partner program (Referral, Co-sell, Reseller) and a programmatic ABM data module distributed through DSPs and agency trading desks. Additional modules include Lead Forensics Chat (managed B2B live chat) and AI/LLM traffic attribution for GEO/AEO measurement; the company holds ISO 27001 certification and is GDPR-registered, and is recognized on G2 as the #1 B2B website visitor identification platform with 47 G2 badges and 28 #1 rankings in its Summer 2026 report.
Lead Forensics serves B2B sales, marketing, and account management teams primarily through direct enterprise field sales and inside sales, with a consultative one-week free trial preceding paid subscription. Enterprise logos such as Xerox, Travelers, Karcher, SpeedyFreight, Toyota Material Handling, Survitec, Cosworth, Helwig Carbon, and Waupaca Foundry sit alongside a broad SMB base that includes Turning Point HR Solutions, Evans Transportation, AW Miller, LightTrans, Sellectronics, and Paragon Marketing. The company claims 10,000+ customers and 60,000+ active users across six offices (London, Portsmouth, Bournemouth, Bristol, Atlanta, Scottsdale) and markets three revenue streams: traffic-dependent software subscriptions, agency channel revenue-share, and programmatic ABM data licensing.
The underlying platform runs a small tracking code comparable to Google Analytics, captures IPs of B2B visitors, applies high-signal modeling and multi-source validation across proprietary data streams, and exposes results through real-time alerts, a lead and pipeline manager, behavior analytics, and decision-maker filtering. Growth has historically been funded internally — no outside capital, funding rounds, or M&A activity are disclosed — under founder-CEO Paul Thomas, with revenue mechanics anchored to traffic-volume pricing, agency channel economics (£5.65 agency client-spend uplift per £1 of Lead Forensics spend), and emerging data-monetization through programmatic channels.
