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.

About

upcell is a lightweight Chrome extension that helps sales and RevOps teams capture LinkedIn leads, enrich contact data, and sync everything cleanly to their CRM—without bloated platforms or overbuilt workflows. Traditional sales data providers are bloated, overpriced, and underused. Teams end up paying for features reps don’t use and data they can’t access. upcell solves this by giving reps a simple tool they’ll actually use, and giving RevOps full control over enrichment coverage, routing, and integrations. With unlimited exporting, real-time mobile and email enrichment, and one-click sync to tools like Salesforce, HubSpot, Outreach, and Salesloft, upcell replaces complexity with clarity. It’s faster, cleaner, and built for the way modern go-to-market teams actually work.
