Warmly

Warmly's visitor identification technology operates as a sophisticated intelligence layer that transforms anonymous website traffic into actionable sales opportunities. When a prospect visits your website, the platform's proprietary de-anonymization engine cross-references IP addresses, browser fingerprints, and behavioral patterns against extensive B2B databases to reveal the visitor's identity with remarkable accuracy. The system captures comprehensive data including company name, industry, employee count, revenue range, and technology stack, along with individual-level details such as the visitor's name, job title, seniority level, LinkedIn profile, and direct contact information. Beyond basic identification, Warmly tracks the visitor's entire journey—which pages they viewed, how long they spent on each, what content they downloaded, and their engagement patterns over multiple sessions. This behavioral intelligence is crucial for understanding buying intent and timing outreach appropriately. Convert anonymous website traffic into qualified leads with immediate outreach opportunities, capturing high-intent prospects before they move to competitors.
