If you are building a company and feel lost about customer success metrics strategy, you are not alone. This phase exists so your Strategy Pack stays honest—not pretty.

What this phase is really about

Customer success design defines how you grow accounts after the sale: onboarding, health scores, expansions, and save plays. Startups formalize before churn surprises; enterprises align CS with sales promises and SLAs.

In Sculptor, CustomerSuccessAgent keeps the conversation anchored to Customer success so you do not mix this work with other phases. That separation is how consultants run engagements: one room, one decision set, one artefact pack.

Why teams skip this (and regret it later)

Sales celebrates logos while silent churn kills LTV. Without CS-METRICS, product learns late that onboarding fails for the ICP that marketing attracted.

Questions this phase must answer

  • What health score predicts renewal or repeat purchase?
  • Which onboarding steps map to CXART moments?
  • When does human touch beat automation for save plays?
  • What expansion triggers are ethical and profitable?
  • How do CS metrics feed PMF and finance models?
  • Which churn reasons are product vs GTM vs support?
  • What SLA commitments are realistic at this stage?
  • How do enterprise QBRs differ from startup check-ins?

Deliverables you should leave with

Customer success artefacts specify health metrics (CS-METRICS) and churn prevention triggers (CHURN-PREV)—linked to CX moments and PMF signals.

  • CS-METRICS-001 definition and thresholds
  • CHURN-PREV-001 playbooks with owners
  • Onboarding journey aligned to CXART
  • Expansion criteria linked to SLS stages

What to prepare before you start

  • CXART maps and support themes
  • Retention data or pilot feedback
  • SLS pilot success metrics

Who should own the answers

Head of CS or founder owns early playbook; product fixes systemic onboarding gaps; sales sets expectation accuracy.
