Lusha is a continuously updating database that provides B2B Salespeople with targeted, accurate, and timely business information. Lusha aggregates its data from multiple sources, cross-checking and updating LIVE to ensure up-to-the-minute data accuracy and database cleanliness.
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.

Most SDR stacks start with a contact database โ ZoomInfo, Apollo, or Lusha โ and treat enrichment as a one-time step at the top of the funnel. The problem: these databases are 3โ18 months stale on average. Job titles change. Companies restructure. Decision-makers who were Director of Engineering in Q1 are VP by Q3. - Source: dev.to / 2 months ago
