Chief Customer Officer Advisor

Strategic customer leadership for startup CCOs and founders without one. Four decisions, no generic CS survey:

1. What's our retention architecture — and is gross retention vs NRR honest? — decomposition into gross retention, contraction, expansion + churn root-cause taxonomy
2. How do we segment customers for differential investment? — tier design + ICP fit scoring + investment-per-segment math
3. What's the CS team's coverage model — and when do we go pooled vs named? — coverage ratio calculator + transition thresholds
4. What CS role do we hire next? — stage-to-role map (CS ≠ Support ≠ AM ≠ Implementation)

This skill does not cover tactical CS implementation. For health-score tooling, CRM workflows, NPS survey infrastructure, or onboarding automation, see business-growth/customer-success-management/ and adjacent tactical skills.

Quick Start

# Decision A: Decompose retention honestly
python scripts/retention_decomposition_analyzer.py                          # embedded B2B SaaS sample
python scripts/retention_decomposition_analyzer.py path/to/cohorts.json

# Decision B: Design customer segmentation + differential investment
python scripts/customer_segmentation_designer.py                            # embedded 4-tier sample
python scripts/customer_segmentation_designer.py path/to/customers.json

# Decision C: Calculate CS team coverage model
python scripts/cs_coverage_calculator.py                                    # embedded 350-customer sample
python scripts/cs_coverage_calculator.py path/to/book.json

Key Questions (ask these first)

• What's your GROSS retention rate? (Not NRR — NRR hides churn behind expansion. Ask gross first.)
• What's the #1 reason customers leave? (If you can't name it, you don't understand churn.)
• What's the median time-to-value (TTV) by segment? (Long TTV in low tier = misfit; long TTV in high tier = onboarding broken.)
• Which customer would you fire today? (If "none" — your segmentation is broken; some accounts cost more than they earn.)
• What's your ARR-per-CSM ratio, and what's the model — pooled or named? (Stage and ACV determine the right answer.)
• Is CS in your comp plan, and how is it different from Sales comp? (CS comp on retention; misalignment is a leading indicator of failure.)

Core Responsibilities

1. Retention Decomposition

The trap: "Our NRR is 115%, retention is great."

The truth: NRR = Gross Retention − Contraction + Expansion. A 115% NRR with 85% gross retention is a leaky bucket masked by upsells. A 115% NRR with 98% gross retention is a healthy product.

Mandatory decomposition every quarter:

| Metric | What it measures | Health threshold (B2B SaaS) | |---|---|---| | Gross Retention (GRR) | $ from existing customers minus churn + contraction | ≥ 90% at growth stage; ≥ 95% at scale | | Logo Retention | % of customers who renewed | ≥ 85% at growth; ≥ 90% at scale | | Net Revenue Retention (NRR) | GRR + expansion | ≥ 110% at growth; ≥ 120% at scale | | Contraction | $ from existing customers reducing seats/usage | < 5% annually | | Expansion | $ from existing customers growing | 15-25% annually at healthy |

Run retention_decomposition_analyzer.py with cohort data for honest decomposition + churn root-cause categorization.

See references/retention_decomposition.md for the 7-category churn taxonomy + leading indicator playbook.

2. Customer Segmentation

The trap: "Every customer is important."

The reality: customers exist on a spectrum of ICP fit × strategic value. Treating them identically wastes CS capacity and ignores expansion opportunity.

4-tier framework (B2B SaaS baseline):

| Tier | ARR range | Coverage | Investment per account/yr | |---|---|---|---| | Strategic | Top 5%, often $100K+ | Named CSM + executive sponsor | $20K-50K | | Enterprise | Next 15-20%, $20K-100K | Named CSM | $5K-15K | | Mid-market | Next 30-40%, $5K-20K | Pooled CSM + automation | $1K-3K | | SMB / Long-tail | Bottom 40-50%, <$5K | Tech-touch + self-serve | $50-500 |

Run customer_segmentation_designer.py to design segmentation tiers + differential investment + ICP fit scoring.

See references/customer_segmentation_strategy.md for ICP fit framework, tier transition triggers, and the kill list (customers below the investment floor).

3. CS Team Coverage Model

The trap: "Hire one CSM per X customers" with a single ratio across all segments.

The reality: coverage model depends on segment, ACV, and complexity. Pooled CSM works for low-touch; named CSM is required for strategic accounts.

Coverage models:

| Model | Best for | Ratio (ARR-per-CSM) | Trade-offs | |---|---|---|---| | Tech-touch (no human) | SMB, low ACV | $5M-15M+ | Automation cost; cannot save high-stakes deals | | Pooled CSM | Mid-market | $2M-5M | Lower cost; less account intimacy | | Named CSM | Enterprise | $500K-2M | Higher cost; deeper relationships | | Named CSM + exec sponsor | Strategic | $300K-1M | Highest cost; reserved for top accounts |

Run cs_coverage_calculator.py with book characteristics to calculate required CSM headcount and identify transition thresholds.

See references/cs_coverage_model.md for ratios, ramp curves, and the "when to add a manager" trigger.

4. CS Team Org Evolution

The wrong question: "Should we hire a CSM or a Support engineer?" The right question: "What's the next customer outcome we're failing to deliver, and what role unblocks that?"

Critical distinctions (founders confuse these):

| Role | Owns | Does NOT own | |---|---|---| | Customer Support | Reactive issue resolution (ticket queue) | Renewal, expansion, success outcomes | | Customer Success Manager | Proactive value realization + renewal + expansion lead | Day-to-day tickets, implementation | | Account Manager | Commercial relationship + expansion close | Day-to-day success, technical depth | | Implementation Manager | Onboarding + go-live | Ongoing success after launch | | CS Operations | Tooling, data, analytics, playbooks | Direct customer relationships | | Customer Marketing | Advocacy, case studies, references | 1:1 customer relationships |

See references/cs_team_org_evolution.md for stage-to-role map (seed → late-stage) + the AM-vs-CSM split decision.

Workflows

Workflow 1: Quarterly Retention Review (4 hours)

Goal: Decompose retention honestly + identify top-3 churn drivers.

# 1. Pull cohort data: closed/won by quarter for last 8 quarters
python scripts/retention_decomposition_analyzer.py cohorts.json
# 2. Review GRR / NRR / contraction / expansion separately
# 3. For each cohort showing GRR < 90%: identify churn root cause (7-category taxonomy)
# 4. Cross-check with cs-cro-advisor: does the expansion math add up?
# 5. Cross-check with cs-cpo-advisor: are product gaps driving churn?
# 6. Output: top-3 leakage points + 90-day mitigation plan

Workflow 2: Customer Segmentation Audit (1 day)

Goal: Re-segment customer base + reset differential investment.

# 1. Build customers.json with ARR, tenure, ICP fit signals
python scripts/customer_segmentation_designer.py customers.json
# 2. Identify segment migration (mid-market → enterprise upgrades, downsells)
# 3. Identify kill list (customers below investment floor)
# 4. Output: new tier assignment + investment-per-tier + kill list for sales review

Workflow 3: CS Team Sizing (1 week)

Goal: Size the CS team aligned to book composition + coverage model.

# 1. Build book.json with current customer base + planned acquisition
python scripts/cs_coverage_calculator.py book.json
# 2. Calculate required CSM headcount by segment
# 3. Compare to current team; identify gaps
# 4. Cross-check with cs-chro-advisor on comp + leveling
# 5. Cross-check with cs-cfo-advisor on the cost
# 6. Output: 12-month hiring plan + role sequence

Workflow 4: CS Team Roadmap (1 week)

Goal: Sequence next 18 months of CS hires aligned to customer outcomes.

1. List top 5 customer outcomes the company is failing to deliver
2. Map each outcome to the role that unblocks it (CSM / AM / IM / Support / CS Ops)
3. Sequence hires; respect prerequisite order
4. Cross-check with cs-chro-advisor
