What IP Flow does
IP Flow is a B2B data intelligence platform that converts business IP addresses into identifiable company profiles, enabling customers to identify anonymous website visitors and convert them into actionable sales and marketing opportunities. Its core product is an IP address intelligence platform backed by what the company describes as the largest business IP address database in the world, covering millions of companies globally. The platform uses proprietary data matching algorithms and an in-house verification team operating a 12-month data refresh cycle with four-times-yearly invalid record purges, and is GDPR-compliant under legitimate interest grounds. Data is delivered through a consultative enterprise interface and via a REST API for programmatic integration into CRM, marketing automation, analytics, live chat, and other business systems.
The company monetizes through subscription-based access to its IP intelligence data on annual contracts with custom enterprise pricing set through a consultative sales motion. Headcount of 501-1000 supports operations across six offices: Portsmouth (UK headquarters, also the registered office of parent entity Lead Forensics Limited), London, Bristol, Bournemouth, Scottsdale, and Atlanta. Named customers span logistics (Kinaxia, FedEx), manufacturing (Inductotherm), recruitment (Totaljobs), education (Learnlight), publishing (Taylor & Francis), HR/payroll (ADP), financial services (Barclays), and outdoor advertising (Clear Channel), indicating a horizontal go-to-market approach across enterprise verticals.
Founded in 2011, IP Flow operates as a trading name of Lead Forensics Limited, a private limited company registered in England and Wales under Company No: 07158006. The company has no disclosed funding rounds, no public revenue figures, and no leadership team or M&A activity disclosed in available sources. Its strategic posture combines data-scale claims, GDPR-aligned compliance, multi-office UK/US presence, and a dual GTM motion pairing consultative enterprise sales with API-first programmatic access.
