CSO — role definition

Purpose: The Client Success Owner (CSO) is the single accountable owner for the client’s success on the engagement: relationship, outcomes narrative, and plan defensibility—not every technical task.


Mission

  • Own the client partnership, sentiment, and renewal posture for assigned accounts.
  • Lead preparation and delivery of the Project Review Meeting with Head of Delivery (see project ownership guide).
  • Partner with the Service Lead so technical approach, timelines, and resourcing are accurate before plans are presented for approval.
  • Translate internal delivery into client-ready value stories (weekly touchpoints, exec conversations).

Accountability

  • RACI “A” for client success outcomes on the account, within SOW.
  • Responsible for client communication cadence and escalation first—before founders, except per Head of Delivery escalation policy.
  • Not the owner of every engineering task—ICs and SL own build execution; CSO ensures milestones and client-visible outcomes are clear and tracked.
