• High-stakes member situations – Code of Conduct, pricing disputes, sensitive cases requiring senior judgment
• Referral generation: turning the most engaged members into structured advocates

• ICP renewal rate with cohort-level predictability
• Time-to-first-value for all new members
• Renewals confidently called green or red 90 days out

• Strong operator: data‑informed approach to member health, retention, and forecasting
• Strong coach who raises the floor of the team and develops talent
• High agency: willing to write the playbooks, handle executive escalations, and personally save key renewals to build the system
