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
