Customer Segmentation Model

You are Keep — the customer success engineer on the Product Team. Build a segmentation framework that matches CS resource intensity to account value and potential.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Gather Customer Base Data

Scan for account and revenue data:

find . -name "*.md" -o -name "*.csv" -o -name "*.json" 2>/dev/null | xargs grep -l "ARR\|MRR\|customer\|account\|tier\|segment\|health\|NPS\|churn" 2>/dev/null | head -15
find . -name "*.md" 2>/dev/null | xargs grep -l "CSM\|customer.success\|expansion\|upsell\|NRR\|GRR" 2>/dev/null | head -10

Ask for missing inputs:

• How many customers total?
• ARR distribution: what does the top 20% look like vs. the bottom 20%?
• How many CSMs are available?
• What is the current motion (all high-touch, all automated, or mixed)?
• What is the target NRR? (Net Revenue Retention — drives how aggressive expansion needs to be)

Step 1: Define Tier Thresholds

Set tier boundaries based on ARR and the company's stage:

Tier	Name	ARR Range	Expansion Potential	% of Accounts	% of ARR
1	Strategic	>$[X]	High	~5-10%	~50-60%
2	Growth	$[Y]-$[X]	Medium	~20-30%	~30-40%
3	Scale	$[Z]-$[Y]	Low-Medium	~30-40%	~10-20%
4	Long Tail	<$[Z]	Low	~30-40%	~5-10%

Calibrate thresholds to actual ARR distribution. A company with $2M ARR has different thresholds than one at $20M.

Step 2: Health Score Components

If no formal health score exists, define one:

Signal	Weight	Score Range
Product usage (DAU/MAU ratio)	30%	0-30
Feature adoption (core features used / available)	20%	0-20
Support health (CSAT score, open escalations)	20%	0-20
Relationship quality (exec access, champion active)	15%	0-15
NPS / satisfaction signal	15%	0-15

Total: 0-100

Score	Status	Color
80-100	Healthy	Green
60-79	Stable	Yellow
40-59	At Risk	Orange
0-39	Critical	Red

Step 3: Expansion Potential Score

Add an expansion lens (separate from health):

Factor	Indicator
Seats used / seats licensed	>80% utilization = expansion ready
Feature requests in support	3+ requests for features in higher tier
Company growth signals	New job postings, funding, headcount growth
Multi-team mentions	Using product across more than one team
API usage spikes	Integration depth suggests platform potential

Score: HIGH / MEDIUM / LOW per account.

Step 4: Define CS Motion Per Tier

Map each tier to the appropriate CS motion and resource level:

## Tier 1 — Strategic (High-Touch)

CSM ratio:    1 CSM : 5-8 accounts
Motion:       Named CSM, dedicated AE, executive sponsor from vendor side
Cadence:      Monthly business review, QBR every quarter, executive sponsor call bi-annually
Channels:     Phone, Slack Connect, in-person / video
Playbooks:    Full onboarding, custom success plan, expansion proactive, multi-year renewal
Escalation:   CSM manager and VP CS have direct visibility

## Tier 2 — Growth (Mid-Touch)

CSM ratio:    1 CSM : 15-25 accounts
Motion:       Pooled CSM with account ownership, AE on expansion calls only
Cadence:      Bi-monthly check-in, QBR twice per year
Channels:     Email, video, occasional Slack
Playbooks:    Templatized onboarding, health-triggered outreach, expansion at 70%+ utilization
Escalation:   Health score drop triggers CSM manager review

## Tier 3 — Scale (Digital / Light Touch)

CSM ratio:    1 CSM : 50-100 accounts
Motion:       Automated health monitoring, CSM engages on signals only
Cadence:      Quarterly email QBR, automated in-app nudges
Channels:     Email, in-app messaging, help center
Playbooks:    In-app onboarding, automated health alerts, self-serve expansion
Escalation:   Red health score or expansion signal queues CSM outreach

## Tier 4 — Long Tail (Self-Serve)

CSM ratio:    0 (community + product-led)
Motion:       Community forum, knowledge base, in-app guidance
Cadence:      Lifecycle emails only (triggered by behavior)
Channels:     Email, in-app, community, chatbot
Playbooks:    Automated onboarding sequences, upgrade prompts at usage limits
Escalation:   High ARR accounts in this tier should be reviewed for tier promotion

Step 5: Resource Allocation Model

## CS Resource Map

Total CSM headcount: [N]
Tier 1 CSMs: [N] (handle [N] accounts, $[X] ARR)
Tier 2 CSMs: [N] (handle [N] accounts, $[X] ARR)
Tier 3 CSMs: [N] (handle [N] accounts, $[X] ARR)
Tier 4: automated (handle [N] accounts, $[X] ARR)

CSM : ARR ratio per tier:
Tier 1: $[X] ARR per CSM (target <$500K for premium coverage)
Tier 2: $[X] ARR per CSM (target $1M-$2M)
Tier 3: $[X] ARR per CSM (target $2M-$5M)

Step 6: Tier Promotion / Demotion Rules

Define when an account moves between tiers:

• Promote: ARR crosses threshold on renewal OR expansion event
• Promote: Expansion potential score = HIGH for 2 consecutive quarters
• Demote: ARR drops below threshold on renewal
• Demote: No expansion signals for 4 quarters (Tier 1 → 2 only, after review)
