About
Heartbeat uses predictive modelling to best guess provider’s contact information. You can confidently expect 84% accuracy on cell phone numbers and 92% on personal emails on your first result. You can manage all members from one account with multiple admins, or have each team manage their own individual account. Their data will still be synced to your contract account so you have access to all data and won’t get charged twice on using a credit on the same contact. Heartbeat provides accurate personal cell phone and personal email data, less business emails that change so frequently. Most list providers will use recycled or permutated business emails which are about 50% accurate. They also do not provide cell phone numbers of providers, like Heartbeat does.

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.
