FAQ

GTM stack: questions

What counts as a GTM stack?

A fixed member list in the Breaknorm technology catalogue: LinkedIn Sales Navigator, Zapier, Make, ZoomInfo, Outreach, Gong, Apollo.io, Clay, n8n, Salesloft, 6sense, Clari, Demandbase, lemlist, Lusha, Instantly, Nooks, Chorus, Attio, Cognism, LeanData, Smartlead, Chili Piper, Qualified, Orum, Clearbit, Hunter.io, Amplemarket, Crossbeam, Bombora, HeyReach, Common Room, Unify, FullEnrich, Seamless.AI, RB2B, Kaspr, Fullcast. A company is "on the stack" when its own postings name at least one member; "two or more" means two different members, not two mentions.

Why does a two-tool threshold matter?

One tool can be a trial or a single rep's habit. Two or three different tools named in postings mean an outbound motion that is staffed and budgeted. That is the segment that buys data, deliverability and enrichment.

Can I filter on this directly?

Yes: the uses_tech filter takes {group: "gtm-stack", min_count: n}. Counting is free, over MCP or the API.
