Purpose

Diagnose overall SaaS business health by analyzing growth, retention, unit economics, and capital efficiency metrics together. Use this to identify problems early, prioritize actions by urgency, and deliver a comprehensive health scorecard for board meetings, quarterly reviews, or fundraising preparation.

This is not a single-metric check—it's a holistic diagnostic that connects revenue, retention, economics, and efficiency to reveal systemic issues and opportunities.

Key Concepts

The Business Health Framework

A SaaS business is healthy when four dimensions work together:

1. Growth & Retention — Are you growing and keeping customers?

• Revenue growth rate
• NRR (Net Revenue Retention)
• Churn rate
• Quick Ratio

1. Unit Economics — Is the business model profitable at the customer level?

• CAC (Customer Acquisition Cost)
• LTV (Lifetime Value)
• LTV:CAC ratio
• Payback period
• Gross margin

1. Capital Efficiency — Are you using cash efficiently?

• Burn rate
• Runway
• Rule of 40
• Magic Number

1. Strategic Position — Are you positioned for sustainable success?

• Market positioning (below, at, above market pricing)
• Competitive moat (network effects, data, brand)
• Revenue concentration risk
• Operating leverage

Stage-Specific Benchmarks

Early Stage (Pre-$10M ARR):

• Focus: Product-market fit, unit economics
• Growth: >50% YoY
• LTV:CAC: >3:1
• Gross Margin: >70%
• Runway: >12 months
• Acceptable: Negative margins, high burn (if unit economics work)

Growth Stage ($10M-$50M ARR):

• Focus: Scaling efficiently
• Growth: >40% YoY
• NRR: >100%
• Rule of 40: >40
• Magic Number: >0.75
• Acceptable: Moderate burn if growth is strong

Scale Stage ($50M+ ARR):

• Focus: Profitability, efficiency
• Growth: >25% YoY
• NRR: >110%
• Rule of 40: >40
• Profit Margin: >10%
• Required: Positive or near-positive cash flow

Red Flag Categories

Critical (Fix immediately):

• Runway <6 months
• LTV:CAC <1.5:1
• Churn accelerating cohort-over-cohort
• NRR <90%
• Magic Number <0.3

High Priority (Fix within quarter):

• Rule of 40 <25
• Payback >24 months
• Quick Ratio <2
• Gross margin <60%
• Revenue concentration >50% in top 10 customers

Medium Priority (Address within 6 months):

• NRR 90-100% (flat, not growing)
• Magic Number 0.3-0.5
• Operating leverage negative
• Churn rate stable but high (>5% monthly)

Anti-Patterns (What This Is NOT)

• Not a single metric: "Revenue is growing 50%, we're great!" (ignoring burn, churn, unit economics)
• Not stage-agnostic: Early-stage burn is acceptable; scale-stage burn is a problem
• Not static: Health is directional—are metrics improving or degrading?
• Not just numbers: Context matters (competitive pressure, market changes, team capacity)

When to Use This Framework

Use this when:

• Preparing for board meetings or investor updates
• Quarterly business reviews (QBR)
• Fundraising preparation (know your numbers)
• Annual planning (identify improvement areas)
• You suspect problems but can't pinpoint them
• New PM/exec joining and needs health assessment

Don't use this when:

• You're pre-revenue (focus on product-market fit first)
• You're in pure research mode (not enough data)
• You need tactical guidance (use specific skills: feature, channel, pricing)

Facilitation Source of Truth

Use workshop-facilitation as the default interaction protocol for this skill.

It defines:

• session heads-up + entry mode (Guided, Context dump, Best guess)
• one-question turns with plain-language prompts
• progress labels (for example, Context Qx/8 and Scoring Qx/5)
• interruption handling and pause/resume behavior
• numbered recommendations at decision points
• quick-select numbered response options for regular questions (include Other (specify) when useful)

This file defines the domain-specific assessment content. If there is a conflict, follow this file's domain logic.

Application

This interactive skill asks up to 4 adaptive questions, then delivers a comprehensive diagnostic with prioritized recommendations.

Step 0: Gather Context

Agent asks:

"Let's diagnose your business health. I'll need metrics across four dimensions: growth, retention, unit economics, and capital efficiency.

Company context:

• Stage: (Pre-$10M ARR, $10M-$50M ARR, $50M+ ARR)
• Business model: (PLG, sales-led, hybrid)
• Target market: (SMB, mid-market, enterprise, mixed)

Why this matters: Benchmarks vary by stage. Early-stage optimizes for growth; scale-stage optimizes for efficiency.

Please provide the following metrics. Use 'unknown' if you don't have a metric."

Step 1: Growth & Retention Metrics

Agent asks:

"Growth & Retention:

1. Revenue:

• Current MRR or ARR: $___
• Revenue growth rate: ___% (MoM or YoY)

1. Retention:

• Monthly churn rate: ___%
• NRR (Net Revenue Retention): ___%
• Quick Ratio: ___ (or I can calculate it)

1. Expansion:

• Expansion revenue as % of total MRR: ___%

1. Cohort trends:

• Are recent cohorts retaining better or worse than older cohorts?

1. Better (improving)
2. Same (stable)
3. Worse (degrading)
4. Unknown"

Based on answers, agent evaluates:

• ✅ Healthy growth: Growth >40% YoY (growth stage) or >25% (scale stage)
• ✅ Healthy retention: NRR >100%, churn <5% monthly, Quick Ratio >2
• 🚨 Growth problems: Growth <20% YoY
• 🚨 Retention problems: NRR <100%, churn >5%, cohort degradation

Step 2: Unit Economics Metrics

Agent asks:

"Unit Economics:

1. Acquisition:

• CAC (Customer Acquisition Cost): $___
• Blended or by channel? (If by channel, what's your best channel CAC?)

1. Value:

• LTV (Lifetime Value): $___
• LTV:CAC ratio: ___ (or I can calculate it)
• Payback period: ___ months (or I can calculate it)

1. Margins:

• Gross margin: ___%
• Contribution margin (if known): ___%

1. Trends:

• Is CAC increasing, stable, or decreasing over time?

1. Decreasing (improving efficiency)
2. Stable
3. Increasing (diminishing returns)
4. Unknown"

Based on answers, agent evaluates:

• ✅ Healthy economics: LTV:CAC >3:1, payback <12 months, gross margin >70%
• ⚠️ Marginal economics: LTV:CAC 2-3:1, payback 12-18 months
• 🚨 Poor economics: LTV:CAC <2:1, payback >24 months, gross margin <60%

Step 3: Capital Efficiency Metrics

Agent asks:

"Capital Efficiency:

1. Cash:

• Cash balance: $___
• Monthly net burn rate: $___
• Runway: ___ months (or I can calculate it)

1. Efficiency ratios:

• Rule of 40: ___ (Growth % + Profit Margin %) (or I can calculate it)
• Magic Number: ___ (S&M efficiency) (or I can calculate it)

1. Operating expenses:

• S&M as % of revenue: ___%
• R&D as % of revenue: ___%
• Is OpEx growing faster than revenue?

1. No (positive operating leverage)
2. Yes (negative operating leverage)
3. Unknown

1. Profitability:

• Profit margin: ___%
• Path to profitability: (already profitable, 6-12 months, 12-24 months, >24 months, unknown)"

Based on answers, agent evaluates:

• ✅ Healthy efficiency: Rule of 40 >40, magic number >0.75, runway >12 months
• ⚠️ Acceptable efficiency: Rule of 40 25-40, magic number 0.5-0.75, runway 6-12 months
• 🚨 Poor efficiency: Rule of 40 <25, magic number <0.5, runway <6 months

Step 4: Deliver Comprehensive Diagnostic

Agent synthesizes all metrics and delivers:

1. Overall Health Score — Healthy / Moderate / Concerning / Critical
2. Dimension Scores — Growth, Retention, Economics, Efficiency
3. Red Flags — Critical, High Priority, Medium Priority
4. Prioritized Recommendations — Top 3-5 actions with expected impact
5. Stage-Appropriate Benchmarks — How you compare to peers

Symptoms:

• NRR 95% (should be >100%)
• Churn rate 5% monthly (should be <3%)
• Expansion revenue only 10% of MRR (should be 20-30%)

Diagnosis: e.g., Customers are churning before they expand. Onboarding is weak, no clear upsell paths.]

Impact:

• Lost MRR: Calculate churn impact]
• Missed expansion: Calculate expansion opportunity]
• Total impact: Combined revenue loss]

Prioritized Action Plan

Immediate (Next 30 days):

1. Fix Primary Issue]

• Action: Specific step, e.g., "Launch onboarding improvement program"]
• Owner: PM, Customer Success]
• Target: Reduce churn 5% → 4%]
• Impact: Save $___K MRR/month]

Short-term (Next Quarter):

2. Secondary Action]

• Action: e.g., "Build premium tier for upsell"]
• Target: NRR 95% → 105%]
• Impact: +$___K expansion MRR]

3. Tertiary Action]

• Action: e.g., "Optimize S&M spend, improve magic number"]
• Target: Magic Number 0.6 → 0.8]
• Impact: More efficient growth]

What Success Looks Like (90 Days)

Target metrics:

• NRR: 95% → 105% (+10pp)
• Churn: 5% → 3.5% (-30%)
• Magic Number: 0.6 → 0.8 (+33%)

Impact:

• Monthly revenue saved from churn: +$___K
• Expansion revenue: +$___K
• More efficient S&M: details]

If you hit these targets, you'll be in 'Healthy' territory.

Monitor Weekly

Must-track metrics:

• Churn rate (track to ensure it's decreasing)
• NRR (track to ensure it's improving)
• Customer feedback (are improvements working?)

Leading indicators:

• Onboarding completion rate
• Time-to-value
• Usage metrics (activation, engagement)

What Not to Do

Don't:

• Scale acquisition until retention is fixed (you'll just churn faster)
• Ignore expansion (it's easier than new acquisition)
• Wait too long (retention problems compound)"

Diagnostic Pattern 3: Concerning Health (Urgent Action Required)

When:

• Multiple critical red flags
• 2+ dimensions problematic
• Requires immediate intervention

Output:

"## 🚨 Overall Health: Concerning (Urgent Action Required)

Your business has multiple critical issues that need immediate attention.

Health Scorecard

| Dimension | Score | Status | |-----------|-------|--------| | Growth & Retention | 🚨 Concerning | Details] | | Unit Economics | 🚨 Concerning | Details] | | Capital Efficiency | 🚨 Critical | Details] | | Overall | 🚨 Concerning | Multiple urgent issues |

• Churn: ___% → reduced by 30% ✅
• NRR: ___% → improving toward 100%

Position:

• Out of crisis mode
• Stable foundation to rebuild growth
• Clear plan for next 6-12 months

What to Avoid

Don't:

• Try to grow your way out of this (fix unit economics first)
• Ignore the data (hope is not a strategy)
• Scale before you fix retention (accelerates failure)
• Wait until runway <3 months to fundraise (too late)

Do:

• Focus ruthlessly on retention and unit economics
• Cut costs to extend runway
• Be honest with board/investors about problems
• Move fast (you don't have time to waste)"

Diagnostic Pattern 4: Critical Health (Existential Crisis)

When:

• Multiple critical failures (LTV:CAC <1:1, massive churn, no path to profitability)

Output:

"## 🚨🚨 Overall Health: Critical (Existential Crisis)

Your business is in survival mode. Immediate drastic action required.

Similar structure to Pattern 3, but more urgent tone, shorter timelines, more drastic measures]

Immediate Actions (This Week):

1. Emergency board meeting
2. Fundraise immediately OR cut burn 50%+
3. Stop all non-essential spend
4. Fix top 1-2 critical issues (runway, unit economics)"

Examples

See examples/ folder. Mini examples below:

Example 1: Healthy Growth-Stage SaaS

Metrics:

• ARR: $20M, Growth: 60% YoY
• NRR: 115%, Churn: 2.5%
• LTV:CAC: 4:1, Payback: 10 months
• Rule of 40: 50, Runway: 18 months

Diagnosis: Healthy. Scale aggressively.

Example 2: Moderate Health (Retention Issue)

Metrics:

• ARR: $15M, Growth: 40% YoY
• NRR: 95%, Churn: 5%
• LTV:CAC: 3.5:1, Payback: 12 months
• Rule of 40: 38, Runway: 12 months

Diagnosis: Moderate. Fix retention before scaling further.

Example 3: Concerning (Multiple Issues)

Metrics:

• ARR: $8M, Growth: 25% YoY (slowing)
• NRR: 88%, Churn: 7% (increasing)
• LTV:CAC: 1.8:1, Payback: 20 months
• Rule of 40: 15, Runway: 8 months

Diagnosis: Concerning. Urgent action on retention and unit economics required.

Common Pitfalls

Pitfall 1: Celebrating Single Metrics

Symptom: "Revenue growing 50%!" (ignoring burn, churn, unit economics)

Consequence: Unsustainable growth. Scaling broken model.

Fix: Look at all four dimensions together.

Pitfall 2: Ignoring Stage-Specific Benchmarks

Symptom: "We're not profitable yet, is that bad?" (early-stage company)

Consequence: Misplaced worry. Early-stage should optimize for growth and unit economics, not profitability.

Fix: Use stage-appropriate benchmarks.

Pitfall 3: Focusing on Lagging Indicators Only

Symptom: "Churn is 5%, let's watch it"

Consequence: By the time lagging indicators (churn, NRR) show problems, it's late.

Fix: Track leading indicators (usage, engagement, onboarding completion).

Pitfall 4: Not Acting on Red Flags

Symptom: "NRR <100% for 3 quarters, but we'll fix it eventually"

Consequence: Problems compound. Becomes crisis.

Fix: Set clear timelines. If metric doesn't improve in X time, escalate.

Pitfall 5: Trying to Fix Everything at Once

Symptom: "Let's improve growth, retention, CAC, and efficiency simultaneously"

Consequence: Resources spread thin. Nothing improves.

Fix: Prioritize top 1-3 issues. Fix sequentially.
