Description
LeadSonar is an innovative platform designed for B2B lead intelligence and sales prospecting, seamlessly integrating lead discovery, email verification, phone enrichment, ICP scoring, and AI-generated outreach openers within a unified workspace. This platform utilizes a sophisticated waterfall cascade that sources information from over 18 data providers, such as LeadMagic, Prospeo, Apollo, Hunter, and RocketReach, prioritizing rapid primary sources while employing fallback providers, and implementing a stop-on-hit mechanism that ceases the search once a verified result is located.
With an impressive 99.9% accuracy rate for emails, a 95% success rate for leads, and the ability to enrich 25 profiles every second, LeadSonar stands out in its efficiency. Each lead enriched through the platform yields more than 30 data fields, enhancing the overall value proposition. Additionally, LeadSonar features advanced AI capabilities, including Sonya, a virtual sales assistant that manages the entire process of searching, verifying, and exporting data via simple English commands, alongside a scoring system that evaluates ideal customer profiles with A/B/C/D grades and a confidence scale from 0 to 100. Furthermore, the platform generates AI-crafted subject lines and opening lines that are specifically customized to align with the respective roles and companies of each lead.
Description
We believe software should serve people, not the other way around.
Scalestack runs repeatable AI work as governed workflows, reachable from the agents your employees already use. Access, spend and a record of every action stay under your control.
Point Scalestack at your data, start from a warehouse table, an application like Salesforce, a CSV or a live webhook. Records arrive the way they really are: incomplete, duplicated and out of date. Chain the steps you need, enrich, validate, score and reconcile in one workflow, from more than 190 modules. Describe it to Attento in plain English, or build it on the canvas. Run over a segment once, refresh it on the cadence the job needs, or process each record the moment a webhook sends it. Scalestack handles the plumbing, the API calls, retries, batching, rate limits, credits and confidence scoring, across hundreds of thousands to millions of rows. Get a clean, current table back, written back to your warehouse and the applications your teams use, or queried by agents over MCP, with the source and reasoning for every value.
Typeform , Astronomer, Clio, Constructor, DigitalOcean, Harvey, Profound, Redis, The Stepstone Group and more run on it. Redis went from 40% to 90% CRM fidelity across 300K records. Typeform enriches in real time at a 92% B2B match rate with sub-5s latency.
Platforms can embed Scalestack inside their own product and ship the AI capabilities never architected for.
