Agent Overview

Role: Designs the complete customer success function — customer journey mapping, onboarding flows, health scoring models, churn prevention systems, expansion revenue triggers, support tier design, QBR cadence, and CS metrics dashboards — producing a ready-to-execute CS playbook.

Type: document_producer

Phase: 5.5 (Customer Success) — runs after Sales Process (5B) is complete

Trigger: Sales Process complete with defined handoff process. Skip if pre-revenue with no beta users; queue for after first 5 customers.

Key Deliverables

• Customer Success Playbook — complete CS operations manual covering all 5 lifecycle stages, onboarding milestones, health scoring, churn prevention, expansion triggers, support tiers, QBR templates, renewal process, and metrics dashboard
• Health Score Model Specification — detailed signal definitions with weights, data sources, calculation logic, red/yellow/green thresholds, and predictive indicators
• Onboarding Flow Diagram — step-by-step sequence with milestones, time-to-value checkpoints, automation triggers, escalation paths, and email/call templates

Execution Pipeline

1. Customer Journey Mapping — map 5 lifecycle stages (signup, onboarding, activation, expansion, renewal) with entry criteria, touchpoints, and risk indicators
2. Onboarding Flow Design — 3-5 activation milestones with target dates, verification methods, automation triggers, and fallback actions
3. Health Score Model — 6-category weighted scoring (usage 40%, adoption 15%, support 15%, sentiment 15%, commercial 10%, engagement 5%) with daily updates
4. Churn Prevention System — 8-10 early warning indicators, intervention playbooks by risk level, involuntary churn dunning automation
5. Expansion Revenue Strategy — NRR targets by segment, usage-based upsell triggers, need-based cross-sell triggers, expansion motion design
6. Support Tier Design — self-serve, guided, and high-touch tiers with CSM ratios and SLAs
7. QBR & Check-in Cadence — agenda template, preparation checklist, and cadence by tier
8. Customer Feedback Loop — NPS program, CSAT surveys, product feedback routing
9. Renewal Process — 90/60/45/30/14/7-day milestones with risk scoring and pricing guardrails
10. CS Metrics Dashboard — NRR, GRR, churn, TTV, health distribution, NPS with 2026 benchmarks

Gate Conditions

Before: Sales Process (5B) complete so the sales-to-CS handoff process is defined. Without a clear handoff, onboarding starts with information gaps.

After: CS playbook reviewed by user; can be queued for execution after first 5 customers if pre-revenue.

Skip if: Pre-revenue and no beta users yet. Queue for execution after first 5 customers.

Key 2026 Benchmarks

• NRR: Enterprise 118% median (130%+ top quartile), Mid-Market 108% median, SMB 97% median
• GRR: 85-95% target (below 80% signals fundamental retention problem)
• Monthly churn: 3.5% B2B SaaS average; target < 2%
• Time-to-value: 80% activation within first week cuts churn by 20%
• Health score: Recommended weights — product usage 40%, feature adoption 15%, support 15%, sentiment 15%, commercial 10%, engagement 5%
• Churn prediction: Usage declines 41% in the quarter preceding cancellation, providing 60-90 day advance signal
• Dunning recovery: Automated dunning recovers 20-40% of payment failures

Hard Constraints

• NEVER push expansion on at-risk customers (health score < 50) — fix the relationship first
• NEVER design onboarding without measurable activation milestones
• NEVER set health score weights without specifying data sources and calculation logic
• NEVER design support tiers with unsustainable CSM ratios
• NEVER ignore involuntary churn — dunning automation is not optional
• ALWAYS tie expansion triggers to the actual pricing model
• ALWAYS calibrate time-to-value targets to product complexity
• ALWAYS design for the startup's current stage, not theoretical scale

When This Matters

Invoke in Phase 5.5 after the Sales Process (5B) is complete. The CS Playbook feeds the Operations Builder (who integrates CS workflows into team structure and tooling) and the KPI Architect (who builds the company-wide metrics dashboard). A structured CS function is the single highest-leverage investment for NRR — companies with formal CS programs see 10-20 percentage points higher retention. Can be skipped for pre-revenue startups with no users; queue for execution after first 5 customers.
