The SaaS Playbook: From $0 to $1M MRR
A synthesis for founders building subscription software businesses. Connects pricing (Cohen), metrics (AARRR), retention (Max MRR), cash flow (annual prepay), PMF (Sean Ellis), and PLG into one SaaS-specific guide.
Step 1: Choose Your Price Point (Cohen)
Your price determines your entire business model. Choose deliberately:
| Price/mo | Customers for $1M ARR | Sales Model | Best For |
|---|---|---|---|
| $10 | 8,333 | Pure self-serve, viral | Consumer-adjacent, high volume |
| $100 | 833 | Self-serve + light touch | Bootstrapped B2B sweet spot |
| $1,000 | 83 | Inside sales, demos | Mid-market B2B |
| $10,000 | 8 | Enterprise sales, pilots | Large company only |
The $100/mo sweet spot: Enough revenue per customer to support basic service, few enough customers to know them personally, low enough price that individuals can approve without a committee. This is where most successful bootstrapped SaaS companies live.
See pricing-strategy and cohen-pricing-business-model.
Step 2: Validate Before Building
Seibel’s two things: write code and talk to users. Nothing else until you have PMF.
- Talk to 30+ potential customers following Mom Test rules
- Build the smallest experiment that tests your riskiest assumption
- Charge from day one — “it’s more important that you are charging than what you’re charging”
- Measure the Sean Ellis score: survey users who’ve used it twice → ≥40% “very disappointed” = PMF
The 90/10 rule: find the version that delivers 90% of the value with 10% of the effort.
Step 3: Nail Activation (onboarding)
The biggest drop-off in SaaS is signup → active user. Fix this before anything else.
- Define your aha moment (the action that predicts retention)
- Measure time-to-value (must be minutes for PLG)
- Guide new users to the aha moment immediately — don’t show a feature tour
- Track: % of signups who reach aha moment within first session
If activation is <30%, nothing else matters. Fix this first.
Step 4: Monitor Your Ceiling (Max MRR)
Cohen’s formula: Max MRR = New MRR ÷ Monthly Churn Rate
| Your Churn | Your Ceiling (at $5K new/mo) | Reality |
|---|---|---|
| 10% | $50K MRR ($600K ARR) | Stuck in small-business zone |
| 5% | $100K MRR ($1.2M ARR) | Viable but constrained |
| 3% | $167K MRR ($2M ARR) | Healthy B2B SaaS |
| 1% | $500K MRR ($6M ARR) | Enterprise-grade retention |
If your ceiling is too low, improving retention is higher leverage than improving acquisition. A 3-point churn reduction can double your ceiling.
Step 5: Optimize the AARRR Funnel
Track pirate metrics and find the bottleneck:
| Stage | SaaS Metric | Healthy | Action if Broken |
|---|---|---|---|
| Acquisition | Signups/week | Growing | Fix positioning, channels |
| Activation | % reaching aha moment | >40% | Fix onboarding |
| Retention | Monthly churn | <5% (B2C), <2% (B2B) | Fix product or product-market-fit |
| Referral | NPS, viral coefficient | NPS >40 | Build sharing into product |
| Revenue | MRR, ARPU, expansion | Growing | Fix pricing-strategy |
Work on the worst stage, not the easiest. Most SaaS founders over-invest in Acquisition when their real problem is Activation or Retention.
Step 6: Unlock Cash Flow (Annual Prepay)
Cohen’s hack: offer annual billing to transform cash flow.
Monthly billing: Spend $80 CAC → recover over 12 months → cash-constrained growth Annual billing: Spend $80 CAC → recover ~$60 immediately → reinvest in growth
Implementation:
- Annual plan: slight discount (~17% off monthly equivalent)
- Monthly plan: slightly higher than 1/12 of annual
- Even 33% annual adoption dramatically improves cash position
- Annual customers self-select as more committed (lower churn)
This is how you grow without VC. See cohen-annual-prepay.
Step 7: Choose Your Growth Model
| Model | How It Works | When to Use |
|---|---|---|
| PLG | Product sells itself; free/trial → paid → team → enterprise | Fast time-to-value, natural sharing |
| Sales-assisted PLG | PLG for land, sales for expand | Mid-market ($1K-$10K/mo) |
| Sales-led | Demos, pilots, contracts | Enterprise ($10K+/mo) |
| Content/SEO | Content attracts, product converts | Long payback but compounding |
| Bootstrap | Revenue-funded growth, no VC | Profitable unit economics, patient founder |
Most SaaS starts with PLG or content, then adds sales as price point increases. See distribution and go-to-market-strategy.
Step 8: Know Your Numbers
The SaaS health dashboard — check monthly:
| Metric | Formula | Target |
|---|---|---|
| MRR | Sum of monthly subscription revenue | Growing |
| ARR | MRR × 12 | Milestone marker |
| Net Revenue Retention | (MRR + expansion - contraction - churn) ÷ starting MRR | >100% |
| LTV:CAC | Customer lifetime value ÷ acquisition cost | >3:1 |
| CAC Payback | CAC ÷ (monthly revenue × gross margin) | <12 months |
| Max MRR | New MRR ÷ churn rate | Above your revenue goal |
| Gross Margin | (Revenue - COGS) ÷ Revenue | >70% |
| Rule of 40 | Revenue growth % + profit margin % | ≥40 |
| Burn Multiple | Net burn ÷ net new ARR | <2x |
The Drake Equation Check
Cohen’s probability model: does every variable have a non-zero chance?
- Viable product? (People pay for it)
- Addressable market? (Enough reachable customers)
- Lasting value? (They stay for months/years)
- Profitable unit economics? (LTV > CAC)
- Sustainable acquisition? (Repeatable channel)
- Founder longevity? (Can you sustain this for years?)
One zero kills everything. Which variable is your biggest risk right now?
