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

ProspectZero is an AI-powered outbound sales platform that automatically identifies high-intent prospects and starts relevant conversations on LinkedIn to generate pipeline on autopilot. Instead of relying on static lead lists, ProspectZero continuously monitors real-time buying signals across LinkedIn, including engagement with competitor content, interactions with industry influencers, keyword-based activity, profile visits, and recent role changes. The platform scores and prioritizes prospects based on fit and intent, ensuring outreach is focused on people who are actively engaged and more likely to respond. Once qualified, ProspectZero’s AI agent initiates personalized LinkedIn conversations, referencing each prospect’s recent activity to create highly relevant messaging. Campaigns run autonomously with multi-step follow-ups, helping users consistently book meetings without manual prospecting.

Pros & Cons from Real Users

Pros

  • As someone who didn’t know what to expect I found it very easy to get started. Having the automation do the repetitive tasks has been great. Matt the founder was also very responsive when we had issues.
  • Love the intent signals. I used to have to pull lists from Apollo and send automated DMs that didn't get much traction. Since using ProspectZero my reply rates have gone from 5-10% to over 25%. The trigger based messaging is very clever.
  • No pro's, the product does not work and if you try to cancel then there's no way to get the refund.Ive been trying to reach them for over two months and all emails & phone numbers dont work when you try to speak to them

Cons

  • Getting the automation to its full potential took sometime. There’s a warmup period for account protection that slowed things down at the start.
  • I think having the ability to review messages before they go out would be helpful for some.
  • No pro's, it product does not work and if you try to cancel then there no way to get the refund.
