Customer Success
Core Principle
The sale is the beginning, not the end. Time-to-first-value is the single most important metric because a customer who never experiences value is a churn statistic waiting to happen.
Onboarding Flows
Time-to-First-Value (TTFV)
TTFV = Time from signup to the moment the customer says "this is useful"
The shorter the TTFV, the higher the retention.
Benchmark targets:
Self-serve SaaS: < 5 minutes
SMB SaaS: < 1 day
Mid-market: < 1 week
Enterprise: < 30 days
Onboarding Design Framework
Step 1: Define the "aha moment"
What's the SINGLE action that makes users stick?
Slack: Send first message in a team channel
Dropbox: Save first file
Zoom: Complete first call
Step 2: Remove everything between signup and aha
Every screen, field, and choice between signup
and aha moment is friction that kills activation.
Step 3: Measure completion rates at each step
Signup → Step 1 → Step 2 → ... → Aha moment
Find where the drop-off is. Fix that step.
Onboarding Checklist Template
IMMEDIATE (first session):
- [ ] Welcome message with clear next step
- [ ] Guide user to one core action (not all features)
- [ ] Show progress indicator
- [ ] Success state when aha moment is reached
DAY 1-3 (follow-up):
- [ ] Email: "Here's what you can do next"
- [ ] In-app: Surface second-most-valuable feature
- [ ] If inactive: Nudge with specific use case
DAY 7 (habit formation):
- [ ] Email: Case study or tip from similar users
- [ ] In-app: Introduce team/collaboration features
- [ ] Check: Has user returned 3+ times?
DAY 14-30 (value confirmation):
- [ ] NPS or CSAT survey
- [ ] Expansion prompt (upgrade, invite team)
- [ ] CSM check-in for higher-tier accounts
Churn Prevention
Churn Segmented by Timing
The critical insight: Churn at different stages has different causes
and requires different interventions.
EARLY CHURN (0-30 days)
Cause: Failed onboarding, didn't reach aha moment
Intervention: Improve onboarding, reduce TTFV
Signal: User never completed core action
MID-TERM CHURN (1-6 months)
Cause: Product doesn't deliver ongoing value, competitor switch
Intervention: Feature adoption campaigns, QBRs, use-case expansion
Signal: Declining login frequency, support tickets
LATE CHURN (6+ months)
Cause: Budget cuts, org changes, contract renegotiation
Intervention: Multi-stakeholder relationships, ROI reporting
Signal: Champion departure, billing contact changes
Churn Analysis Template
| Metric | Calculation | Target |
|---|---|---|
| Monthly churn rate | Lost customers / Start-of-month customers | < 5% (SMB), < 1% (enterprise) |
| Revenue churn | Lost MRR / Start-of-month MRR | < 2% monthly |
| Net revenue retention | (Start MRR + expansion - contraction - churn) / Start MRR | > 100% (ideally 120%+) |
| Logo churn | Lost logos / Start-of-month logos | Track alongside revenue churn |
NPS / CSAT Measurement
NPS (Net Promoter Score)
Question: "How likely are you to recommend [product] to a colleague?" (0-10)
Segments:
Promoters (9-10): Loyal fans — ask for referrals and testimonials
Passives (7-8): Satisfied but switchable — find what's missing
Detractors (0-6): At risk — intervene immediately
NPS = % Promoters - % Detractors
Benchmarks:
> 50: Excellent
30-50: Good
0-30: Needs improvement
< 0: Problem
CSAT (Customer Satisfaction Score)
Question: "How satisfied are you with [specific interaction]?" (1-5)
CSAT = (# of 4-5 responses / Total responses) × 100
Use CSAT for specific touchpoints:
- Post-onboarding
- After support ticket resolution
- After feature release
- Post-QBR
Use NPS for overall relationship health.
Survey Timing
NPS: Quarterly (or after major milestones)
CSAT: After specific interactions (support, onboarding, call)
CES (Customer Effort Score): After task completion
Rule: Never survey more than once per month per customer.
Customer Health Scoring
Health Score Components
| Signal | Weight | Green | Yellow | Red |
|---|---|---|---|---|
| Product usage (DAU/WAU) | 30% | Above average | Declining 2+ weeks | Inactive 30+ days |
| Feature adoption | 20% | Using 3+ core features | Using 1-2 features | Only login feature |
| Support sentiment | 15% | Positive CSAT | Neutral | Negative or escalations |
| NPS | 15% | Promoter (9-10) | Passive (7-8) | Detractor (0-6) |
| Engagement (meetings, training) | 10% | Regular QBRs | Occasional contact | No response to outreach |
| Contract signals | 10% | Expansion discussions | Flat renewal | Downgrade or at-risk |
Health Score Actions
GREEN (80-100): Expansion opportunity
→ Ask for referrals, case studies, upsell
YELLOW (50-79): Intervention needed
→ Schedule check-in, identify blockers, re-onboard on unused features
RED (0-49): Churn risk
→ Executive outreach, save plan, offer concessions if warranted
Anti-Patterns
| CS Theater | Real Customer Success |
|---|---|
| "We have a help center" | Proactive onboarding that guides to aha moment |
| Measuring NPS but never acting on it | Detractor follow-up within 48 hours |
| Treating all churn the same | Segmenting by timing and tailoring interventions |
| Health score based only on logins | Multi-signal health score with actionable thresholds |
| CS only talks to customers who call | Proactive outreach to yellow and red accounts |
Power Move
"Design a customer health scoring model for [product]. Define the aha moment, build an onboarding flow that minimizes TTFV, create a churn analysis segmented by timing (early/mid/late), and write the intervention playbook for each health score tier."
The agent becomes your head of customer success — turning onboarding into retention and retention into expansion.
