Know the metrics that matter at each stage and what investors actually look for. Master the A16Z and YC frameworks for measuring startup progress.

• Fundraising prep to know which metrics to highlight
• Board meetings to report on the right KPIs
• Strategic planning to set goals that matter
• Product decisions to understand what to optimize
• Diagnosing problems to find what's broken
• Benchmarking to know if your metrics are good

1. Identifies key metrics by stage - What to measure when
2. Calculates core SaaS metrics - ARR, MRR, churn, LTV, CAC
3. Benchmarks performance - Good vs. great vs. concerning
4. Diagnoses metric problems - What poor metrics indicate
5. Prepares investor-ready dashboards - What VCs want to see
6. Prioritizes metric improvement - What to fix first

• New MRR: Revenue from new customers
• Expansion MRR: Upgrades and cross-sells
• Contraction MRR: Downgrades
• Churned MRR: Lost customers

1.0 = Very efficient 0.75-1.0 = Good <0.5 = Inefficient

40% = Healthy balance of growth and profitability

2x = Concerning

4 = Excellent growth quality

---

• Logo churn: 3-5% monthly
• NRR: 80-100%
• LTV/CAC: >3x
• CAC: <$1,000

• Logo churn: 1-2% monthly
• NRR: 100-120%
• LTV/CAC: >4x
• CAC: $5,000-20,000

• Logo churn: <1% monthly
• NRR: 110-150%
• LTV/CAC: >5x
• CAC: $20,000-100,000+

1. Market saturation (ran out of easy customers)
2. Product-market fit weakening (competition, changing needs)
3. Sales inefficiency (declining magic number)
4. High churn eating new growth

• Is logo churn increasing?
• Is CAC increasing?
• Is conversion rate declining?
• Is expansion revenue flat?

1. Onboarding problems (never got value)
2. Product gaps (missing critical features)
3. Wrong customers (sold to people who shouldn't buy)
4. Competition (better alternatives emerged)
5. Pricing mismatch (not worth it)

• When do customers churn? (early = onboarding, late = value)
• What's the churn reason? (survey departures)
• Which segments churn most?
• What's usage pattern before churn?

1. Wrong channel (expensive acquisition)
2. Poor targeting (low conversion)
3. Weak positioning (hard to differentiate)
4. Long sales cycles (expensive process)
5. Market competition (bidding up costs)

• What's CAC by channel?
• What's conversion rate at each stage?
• How long is sales cycle?
• What's win rate vs. competition?

1. High churn (short lifetime)
2. Low ARPU (underpriced or wrong segment)
3. No expansion revenue (no upsell path)
4. Low gross margin (cost too high)

• What's average customer lifespan?
• What's ARPU distribution?
• What's expansion revenue %?
• Are costs scaling with revenue?

• MRR and growth trajectory
• Customer count and retention
• Engagement metrics
• Early unit economics (if available)

• ARR and YoY growth
• Net Revenue Retention
• LTV/CAC ratio
• CAC Payback
• Cohort analysis
• Customer breakdown by segment

• Magic Number
• Rule of 40
• Burn Multiple
• Detailed unit economics by segment
• Efficiency trends over time

• ARR: $[X]
• MRR: $[X]
• MoM Growth: [X]%
• YoY Growth: [X]%

• Total Customers: [X]
• New This Month: [X]
• Churned This Month: [X]
• Logo Churn Rate: [X]%

• Gross Revenue Retention: [X]%

• LTV/CAC: [X]:1
• Payback: [X] months

• Gross Margin: [X]%
• Magic Number: [X]
• Burn Multiple: [X]

• DAU: [X]
• DAU/MAU: [X]%
• Feature adoption: [X]%

"I'm raising Seed. Here are my metrics. How do they look?" MRR: $15K, 6 months old, 40 customers MoM growth: 20% average Churn: 5% monthly CAC: $200

• Customer lifespan: 1 / 0.05 = 20 months
• LTV = $375 × 20 = $7,500

• Growth rate is healthy (20% MoM = 8.9x annual)
• CAC is very efficient
• LTV/CAC is strong (though churn may be early-stage noise)

• 5% monthly churn = 60% annual churn (high for SaaS)
• Small sample size (40 customers)
• Need to see cohort retention to understand true churn

1. Is 5% churn consistent across cohorts or improving?
2. What's the activation rate? (Are churners ever getting value?)
3. What's usage pattern of retained customers?

• ✅ Growth trajectory (20% MoM is good)
• ✅ Efficient acquisition
• ⚠️ Retention story (need cohort data)
• ❓ Path to scale

• Highlight growth and CAC efficiency
• Show cohort data if recent cohorts retain better
• Explain what you're doing to improve retention
• Project what metrics look like with improved retention

"My MoM growth dropped from 25% to 8% over 4 months. What's happening?"

• Are you acquiring the same # of customers but losing more?
• Check: New MRR vs. Churned MRR

• Are you getting fewer new customers?
• Check: New customer count, pipeline, conversion rate

• Has expansion revenue slowed?
• Check: Expansion MRR trend, upsell rate

1. Get the data breakdown (above table)
2. Identify primary driver (acquisition, churn, or expansion)
3. Root cause analysis on that driver
4. Hypothesis and test solutions
5. Monitor leading indicators weekly

"Am I ready for Series A? ARR: $1.2M, NRR: 108%, LTV/CAC: 4.5x, YoY growth: 180%"

1. CAC Payback? (Need to calculate)
2. Gross Margin? (Should be >70% for SaaS)
3. Logo vs. Revenue Churn? (Both matter)
4. Cohort data? (Do later cohorts retain better?)
5. Segmentation? (Which customer type is best?)
6. Magic Number? (Sales efficiency)
7. Path to $10M ARR? (How do you 8x?)

1. Strengthen weak spots before raising:
   • Calculate and optimize CAC Payback
   • Document gross margin
   • Build cohort analysis
2. Prepare growth story:
   • What drives growth? (channels, segments)
   • Why will this continue?
   • What does $10M ARR look like?
3. Document efficiency:
   • Magic Number (if positive)
   • Burn Multiple (if reasonable)

• Structuring strategic analysis
• Identifying market opportunities
• Creating strategic frameworks
• Synthesizing competitive data

• Replace market research
• Guarantee strategic success
• Know proprietary competitor info
• Make executive decisions
