The annual reference for fractional CMO engagement norms. Pricing, scope, engagement length, success criteria, common deliverables, and the operational shifts the role is undergoing as AI-native models gain share. Built from cross-portfolio observation and operator interviews. Citable. Refreshed annually.
Synthesis of (a) Treetop's own engagement data across mid-market clients, (b) operator interviews with 30+ practicing fractional CMOs, (c) cross-referenced public benchmarks from peer reports, (d) compensation data from fractional executive networks. Numbers are reasonable industry midpoints, not statistical claims — fractional engagements vary widely by company stage, vertical, and scope. Refreshed May 2026; next refresh May 2027.
