LeadSonar is a participant in the agentic sales stack through its Sonya agent. Sonya is a natural language interface that automates the multi-step process of prospecting, which traditionally required human intervention at every stage: filtering, verifying, and drafting. By allowing users to define a task in plain English and having the agent execute the data retrieval and enrichment, LeadSonar moves sales intelligence from a passive data repository to an active participant in the workflow.
The platform is relevant to the broader agent ecosystem as it provides the 'ground truth' data that other sales agents require to function. Whether through its own internal agent or its REST API, LeadSonar provides the verified contact information and ICP grading necessary for autonomous outbound systems to operate without human oversight. It effectively acts as a data-rich environment where agents can perform high-fidelity prospecting tasks.
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, People Data Labs, Lusha, ContactOut, Findymail, Dropcontact, Snov.io, Kaspr, Wiza, and Clearbit), 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.
Pricing follows a pay-per-lead, zero-waste credit model rather than annual subscription lock-in. Plans start with a free 7-day trial of 1,000 leads (no credit card required). A REST API supports synchronous email and phone lookups, async bulk enrichment up to 100 contacts per job, and direct one-click sync into HubSpot and Salesforce.
LeadSonar is built for B2B SaaS sales teams, GTM and RevOps teams, outbound agencies, SDRs, BDRs, AEs, founders, and growth leaders who want to replace Apollo, ZoomInfo, Lusha, and standalone email verification tools with a single waterfall-powered workspace. Compared to single-vendor databases that refresh weekly or monthly, LeadSonar verifies in real time, refunds instantly on verification failure, and bills only for providers that actually returned data.
