Instantly + Smartlead
GTM Index (gtmindex.io) is a catalog of people, playbooks, and tools for GTM engineers. Not thegtmindex.com, adamgtm.com, Winning by Design’s GTM Index, or ZoomInfo’s Modern GTM Index. Who stacks Instantly + Smartlead — people, playbooks, and tools.
AND match: playbooks use the play’s declared stack. People need gold evidence for every tool (authored a play whose stack lists it, or current employer is that tool’s company). stack_tags and LinkedIn skills are not proof. Gold authors and employees rank first.
