Common questions
- What is the System of Record layer?
- The ledger the business commits to and reports from. It serves Functional Coherence in the eight-layer model of revenue architecture. Everything else has to reconcile against it.
- Which tools do operators run in the System of Record layer?
- 4 tools are placed in the System of Record layer, 3 of them named by an operator running them in a working system. The most-named are HubSpot (3 operators), Salesforce (3 operators) and Graft (1 operator).
- How does a tool get placed in the System of Record layer?
- A tool is placed by the function it performed in a named operator's system, described on a Show Me Your Stack or GTM Vault Podcast episode, or by a GTM Vault essay recommendation. The two grades are shown separately and never blended. Placement is not for sale.
