The Stack Index / Method

Method

A tool enters this index only where a named operator described using it in a working system, or where GTM Vault recommended it in an essay. Those two are never blended.

Inclusion

  1. One citation per episode where a named operator described the tool in a working system.
  2. Mentions in passing, sponsor reads, guest biographies and podcast player links are discarded.
  3. Products belonging to the guest's own company are excluded from every recommendation and listed separately below.
  4. Tools are placed by the function they performed, not by the category their marketing claims.
  5. Budget is a posture, not a price. Public pricing in this category is unreliable, so no dollar figures appear anywhere.
What cannot be bought. Placement here is not for sale. Sponsorship moves nothing into a layer and nothing up a list. There is no field in the data model for it, by design. Vendors are added when a named operator describes running the tool in a working system. Want in? Get a customer on Show Me Your Stack. Logos are shown for recognition only and change nothing about order.

Appeared as a guest, not as a recommendation
