About

LeadSonar is a B2B lead intelligence and sales prospecting platform that consolidates lead discovery, email verification, phone enrichment, ICP scoring, and AI-written outreach openers into a single workspace. The platform runs a waterfall cascade across 18+ data providers (including LeadMagic, Prospeo, Apollo, Hunter, RocketReach etc.), tiered from primary fast sources to fallback providers, with stop-on-hit logic that halts the cascade the moment a verified result is found. LeadSonar delivers 99.9% email accuracy, a 95% catch rate and bulk enrichment throughput of 25 profiles per second. Each lead returns 30+ enrichment fields. Native AI features include Sonya, a sales agent that runs end-to-end search, verification, and export from a plain-English prompt; ICP scoring with A/B/C/D grades and 0-100 numerical confidence; and AI-written subject lines plus first-line openers tailored to each lead's role and company.
