B2B Website Visitor Identification
Our core service identifies anonymous B2B website visitors by matching IP addresses against the world's largest proprietary database. This enables businesses to discover which companies are visiting their website, track visitor behaviour patterns, and obtain detailed contact information for key decision-makers. The solution provides real-time alerts when high-value prospects engage with website content, allowing sales teams to prioritise outreach efforts effectively.
CRM Integrations
We offer seamless integration with major CRM platforms including Salesforce, HubSpot, and Microsoft Dynamics. Our technology automatically syncs visitor data with existing sales pipelines, enabling teams to maintain workflow continuity while gaining enhanced prospect insights. The integration supports both one-way data flow for basic implementations and complex two-way 'fuzzy matching' for enterprise organisations with high-traffic websites and multi-team operations.
Account Management Analytics
This service provides detailed analytics for existing customer accounts, tracking website engagement patterns to identify upsell and cross-sell opportunities. By monitoring which pages and content prospects interact with, businesses can tailor their account management strategies with data-driven insights. The system generates alerts when existing customers show renewed interest or require support, enabling timely interventions to improve retention and satisfaction.
Marketing Performance Tracking
Our platform tracks the effectiveness of marketing campaigns by linking website traffic to specific lead generation activities. Marketers can analyse which campaigns drive high-quality visitors, measure content engagement levels, and identify underperforming channels. The service provides detailed reports on visitor demographics, firmographics, and behavioural patterns, enabling data-driven optimisation of marketing strategies and budget allocation.
Data Import Services
This feature allows businesses to upload their Ideal Customer Profile (ICP) data for enhanced targeting. The system matches uploaded data against real-time website visitors, providing instant alerts when priority prospects engage with content. The service supports segmentation by geography, company size, industry sector, and other firmographic criteria, enabling precise audience targeting and personalised outreach strategies.

Lead Forensics has been a great tool for us, really helping us understand exactly how our marketing channels are driving traffic but also understanding the relevance to enable changes to what we do to then convert them into sales ready leads for the business. Our Customer Success Manager Michael is absolutely great and without him we would not even know where to begin. Great guidance and always on hand to help when we need it. Highly recommend to any business looking to make a difference to the way they work and ask for Michael to look after you.

Jay Norton is our contact with Lead Forensics and is awesome to work with! His training had us up and running in no time and I highly recommend him when it comes to setting your system up. We are very pleased and look forward to producing more leads in the future!
