Module 0: Start Here
Before the metrics and the playbooks, you need the mental model: what makes a subscription business different from every other kind, why recurring revenue changes every decision you'll make, and how the six modules of this course fit together into one growth system.
Why SaaS is a different business
A subscription business sells the same thing every month to the same customer. That one fact changes everything. In a one-time-sale business, the transaction is the finish line — you close the deal, collect the money, and move on to the next stranger. In SaaS, the transaction is the starting line. The real money is made in month six, month twelve, month thirty-six — every month the customer stays.
Do the math on a $49-per-month product. One customer who stays three years is worth $1,764. A customer who cancels after two months is worth $98. Same signup, same acquisition cost — eighteen times the revenue. This is why SaaS companies obsess over retention the way other businesses obsess over closing. The sale doesn't end at signup; it ends at cancellation.
Recurring revenue also compounds. Add 20 customers a month and lose 5, and your base grows by 15 every month — on top of everything you already built. Month one's work still pays you in month twelve. No other common business model does this. But the compounding cuts both ways: lose more customers than you add, and the business shrinks on autopilot while you're busy celebrating new signups.

The growth system, not the growth hack
SaaS growth is a system with five stages: acquire (get signups), activate (get them to first value), retain (keep them paying), expand (grow their accounts), and refer (turn them into your marketing). Every stage feeds the next. A weakness anywhere in the chain caps everything downstream — brilliant acquisition can't save broken activation, and perfect retention can't save a product nobody discovers.
Most struggling SaaS companies don't have a growth problem — they have a stage problem they haven't diagnosed. They pour money into ads (acquire) while 70% of signups never activate. Or they celebrate low churn while acquisition has quietly stalled and the base is aging out. You can't fix what you haven't measured, which is why Module 1 comes before everything else.
Forget growth hacks. A hack is a tactic that worked once, for someone else, in different conditions. A system is a set of metrics you review monthly, experiments you run continuously, and playbooks you improve every quarter. This course gives you the system: the dashboard (Module 1), the acquisition engine (Module 2), the activation machine (Module 3), the churn defense (Module 4), and the expansion ladder (Module 5). Run all five and growth stops being luck.

How this course works
Six modules, in order. Module 1 builds your metrics dashboard — MRR, churn, CAC, LTV, NRR — with the actual formulas, so every later module has numbers to work with. Module 2 covers product-led acquisition: free trials, freemium, and viral loops. Module 3 is onboarding and the 10-Minute Test. Module 4 is the Churn Audit and the full churn defense. Module 5 is the Expansion Ladder and growing revenue from customers you already have.
Three ideas will follow you through the whole course, so learn them now. The 10-Minute Test (coined term): if a new user can't reach real value within ten minutes of signing up, your onboarding is broken — fix the path, not the user. The Churn Audit (coined term): a systematic review of exactly why customers leave, ranked by impact, so you fix the biggest leak first instead of guessing. The Expansion Ladder (coined term): the planned path from your entry tier to your top tier, with clear rungs and triggers, so accounts grow on purpose instead of by accident.
As you go, use the build brief prompts in each module — they're collecting your answers into a growth plan document you'll download at the end. And do the 24-hour actions: this course pays off when you apply each module to your own numbers, not when you finish reading. Your business is the coursework.
