Direct answer
A fractional CMO leads marketing strategy and execution. An AI GTM consultant designs the data, signal, account research, scoring, AI workflow, and RevOps layer that makes technical outbound smarter.
What a fractional CMO is good for
A fractional CMO can help with positioning, messaging, campaigns, content, lifecycle marketing, team structure, and channel strategy. That is useful when the marketing motion is the bottleneck.
What an AI GTM consultant should own
The AI GTM layer asks different questions: what signal predicts need, where that signal appears, how accounts should be scored, what context sales needs, and how AI should support research without making outreach generic.
Why LeadCognition matters here
LeadCognition shows the pattern in practice: GitHub behavior becomes account signal, account signal becomes prioritization, and prioritization becomes better DevTool GTM timing.
