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 account
