Where the instrumentation lands
Tools placed on each of the eight layers of revenue architecture, in build order. The bar is tools placed; the gold share is operator verified.
Sequencing is empty by definition: it is the decision about which layer to build first, and no product makes it.
Where operators agree
Tools with two or more operators describing them in working systems. Operators who named a tool only as displaced are not counted as use. A mark means GTM Vault’s own stack (GTM 50) is one of the operators; 22 of 22 hold at two or more without it.
Displacements on the record
Recorded only when the operator said so on an episode. Never inferred from usage or reviews.
- CLI orchestration displaced Clay. Tim Scheuer, Oxygen, SMYS 6.
- Clay displaced ZoomInfo. Elliot O'Connor, Frontier, SMYS 8.
New on the record in Q3 2026
10 tools had their first operator citation between 1 Jul 2026 and 24 Sep 2026.
Budget posture
Self-serve 53 (52%), Mid-market 34 (33%), Enterprise 15 (15%). Posture, not price: public pricing in this category is unreliable, so the index records the tier a tool enters at.
Method and limits
One citation per episode, only where the operator described the tool doing a job in a working system. The Q3 2026 sample is 25 operators across 17 GTM Vault Podcast episodes and 8 Show Me Your Stack episodes, plus 8 GTM Vault essays and 1 post-episode addition confirmed directly by an operator. The sample is small and self-selected: operators who agreed to show their stack on the record. GTM Vault’s own stack counts as one operator and contributes to 8 of the 22 consensus tools. Full rules are on the method page; the raw data is at /stack/stack.json.
Common questions
- What GTM tools do operators use most in Q3 2026?
- On the Stack Index as of 24 Sep 2026, the tools named by the most operators running them in working systems are Clay (8), Apollo (7), Claude (6), Claude Code (6), Slack (6). 22 tools have two or more operators agreeing. The count is one citation per episode, from 25 operators across 25 GTM Vault episodes.
- Where do GTM stacks concentrate their tools?
- Motion and Distribution hold the most tools, 28 and 26 of 102. Pricing holds 2 and Sequencing holds none, because sequencing is a decision made by a person with the whole system in view, not a product. Vendors build where activity is visible in week one.
- Which GTM tools replaced other tools in operators' stacks?
- Displacements on the record in the Stack Index: CLI orchestration displaced Clay (Tim Scheuer, Oxygen, SMYS 6); Clay displaced ZoomInfo (Elliot O'Connor, Frontier, SMYS 8). A displacement is recorded only when the operator said so on an episode.
- How is the State of the Operator Stack report measured?
- Each tool enters the index only where a named operator described running it in a working system on a GTM Vault episode, or where a GTM Vault essay recommended it; the two grades are never blended. The Q3 2026 sample is 25 operators, 17 podcast episodes, 8 Show Me Your Stack episodes and 8 essays. The report is a frozen snapshot taken 24 Sep 2026.
