# 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

```bash
# 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.

```bash
# 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.

```bash
# 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.

```bash
# 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

## Output Standards

```
**Bottom Line:** [one sentence — decision and rationale]
**The Decision:** [one of: retention | segmentation | coverage | next hire]
**The Evidence:** [numbers from the tool, not adjectives]
**How to Act:** [3 concrete next steps]
**Your Decision:** [the call only the founder can make]
```
