About

GTM OS is AI outbound infrastructure for B2B revenue teams; one operated AI agent deployed behind the outbound stack you already pay for. It replaces the enrichment, signal, intent, workflow, and TAM-building layer while your CRM and sequencer stay in place. It is not a new UI your team has to log into; it is an AI agent that operates a four-system back end, configured in a single YAML file, run at your command, and designed to land output daily where your team already works. It collapses fragmented tools into one operated layer across TAM, Signal, Enrichment, and Delivery. TAM builds and refreshes the addressable account universe, expands beyond LinkedIn TAM, scores accounts at ingest, and keeps them fresh. Signal runs buckets such as Expansion, New Sheriff, and Leaky Bucket, plus custom signals built to your ICP and scored by intensity. Enrichment uses Cascade, with probabilistic routing across 15+ data sources and AI fallback.

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.
