THE GROWTH COURSE BUILD · PILLAR D
When can you
quit the job?
Let the numbers say.
A product people pay for. Strangers finding it. And a question you ask yourself every Sunday night, with no honest way to answer it. This is how you grow on evidence — and know the number that lets you leave.
Six numbers in one weekly sheet, one experiment at a time, a week you can keep for years beside a job — and your replacement number, worked out honestly. AI does the counting. You make the call.

number that lets you quit
Not a dashboard. Not a growth hack. A number you can trust, and a decision you can defend.
01THE TRUTH
Growing on feel is how side projects stall.
You don't know what's working
Customers arrive from somewhere. Some leave. You spend your six hours on whatever feels urgent this week.
One bad week feels like the end
A cancellation on Tuesday and you're rewriting everything. With small numbers, mood is louder than evidence.
The hours keep leaking
A heavy month at work and the product goes quiet for three weeks. There's no rhythm that survives the job.
"When can I quit?" has no answer
You've done the maths in your head a hundred times. It's never the same number twice.
It was never the effort. It was deciding without the numbers.
02THE OTHER SIDE
What changes when the numbers decide.
→ You know which route brings customers — and stop the ones that don't.
→ A bad week is a bad week, not a verdict.
→ Every change is a bet with a bar, tested one at a time.
→ A week you can keep for years, beside the job.
→ You know your replacement number, and exactly how far you are.
→ And when you leave — if you leave — it's on evidence, not a bad Monday.
03LET'S BE HONEST
"Just grow" is not a strategy.
Most growth advice assumes a team, thousands of users and a dashboard. With tens of customers and six hours a week, percentages lie and benchmarks mislead. The job is smaller and more honest: count a few things every week, change one thing at a time, and let the numbers — not your mood — decide.
✕ What growing on gut feel produces
✕ Chasing whatever feels urgent.
✕ Rewriting the product after one cancellation.
✕ Ten metrics, none of them read.
✕ A schedule that collapses in a heavy month.
✕ Quitting on a good month — or never.
✓ What growing on the numbers produces
✓ Six numbers, counted every Sunday.
✓ Trends read over four weeks, reasons read every week.
✓ One experiment at a time, with a bar written first.
✓ A week you can keep for six months.
✓ A replacement number and an honest call.
04THE GROW ROWWHAT YOU'LL HAVE AT THE END
22
Hours & Walls
A schedule you could keep for six months, and nothing of your employer's touching the product.
23
The Weekly Rhythm
The Sunday review, one big thing, the deep block — and selling every week, not just building.
25
The Number
Your replacement number, coverage over three straight months, runway — and a quit-readiness score out of 14.

Module 01
Numbers, Not Ego
What "data-driven" means for one person with a job and tens of customers, and what it does not: decisions made on records instead of mood, ego and other people's numbers.
See what has really been driving your decisions, name the four decisions the numbers exist to serve, learn why small numbers need a different reading, set the AI up to count, summarise and challenge without deciding, and see where this course is going: the GROW row, box 25 and an honest call.

Module 02
The Few Numbers That Matter
Six numbers, defined exactly, counted in one weekly sheet every Sunday: paying customers, MRR, new, lost, where each new one came from, and the first win within 48 hours. No dashboards. Private.
Define the six numbers for your product and count each one exactly, build the weekly sheet with AI beside the Income Course's monthly money sheet and check it until you trust it, run the Sunday count in about ten minutes, and keep every number in it private.

Module 03
Reading Small Numbers
With tens of customers, the numbers can tell you a great deal, as long as you read the people before the percentages and give it four weeks before you believe it.
Read your weekly sheet honestly at tens of customers: in counts and people rather than percentages, in four-week blocks rather than single weeks, with one test that separates a signal from a bad week, the sheet's blind spots looked into on purpose, and an AI reading you know how to judge.

Module 04
One Change at a Time
One bet, one bar written first, one date: the honest experiment for a business with tens of customers.

Module 05
Hours and Walls
A schedule you could keep for six months, beside the job, and nothing of your employer's touching the product.
Build a weekly schedule from slots that have already held, place a budget across the four kinds of work with deliberate margin, protect it with rules that shrink instead of catch up, plan the heavy month down to a floor, keep the four walls as a system you check, and fill box 22 on the evidence.

Module 06
The Weekly Rhythm
The week that keeps you selling, building and sane: one review, one big thing chosen from the numbers, one deep block, a daily thread, and selling in every single week.
Turn the hours from box 22 into a fixed weekly shape: a thirty-minute Sunday review of the sheet, one priority a week chosen from the numbers, a protected deep block, ten minutes a day in the home room, and selling in every week, with the review run with AI and every answer judged.

Module 07
Where to Grow
Double down on what your own numbers say works — the route, the product, the price — stop what doesn't, and make each change one at a time.
Read your weekly sheet and logs for what is producing, give more of your fixed hours to the routes that bring paying customers, build what customers' reasons point to, change the price for new customers only when a real improvement has shipped, stop what takes hours without producing, and put every growth decision through an honest attack before you make it.

Module 08
The Number
What the business must bring in each month to replace what the job does for you, built from your own figures, and exactly how far you are from it.
Build your replacement number in five lines from your own spending, what the job provides, the business's real bills and your accountant's answer on tax and contributions; divide your MRR by it to get coverage; know why coverage only counts when it holds for three straight months; state the honest gap in euros and customers; and turn what could close it into one bet.

Module 09
Quit When Ready
Coverage, durability, runway and a strict score out of 14: make the honest call on whether the business can replace the job, write the rule and the date for next time, and, if the answer is yes, leave well.
Read coverage over three straight months, judge whether the numbers are holding, count your runway strictly, score yourself out of 14 with the load-bearing vetoes, reach YES or NOT YET with a written rule, a date to look again and bets that could change it, and know how to leave well if you choose to.

Module 10
The GROW Gate
Find out whether the GROW row is real and box 25 is honest, make the call on your records, review the whole canvas in one sitting, and send the next big bet back to B.
Audit and review boxes 22–24 against their strict readings and box 25 for honesty, apply clear rules to reach GO, NOT YET or KEEP BUILDING, review all three canvases and the whole BUILD method in one sitting, set up the next big bet back at validation, and write the one page that runs the business until your next look.

WHY THIS COURSE
I was 45. I'd lost €250,000.
That venture needed a co-founder, money and quitting first — everything this site tells you that you don't need.
Then I built roughly €2M of software on my own with AI, for about €3,250 in tools, over twelve months.
AI can count faster than you. It can't decide what the numbers mean for your life, or when you can leave. That is what this course teaches.
07INCLUDEDEVERYTHING YOU NEED TO GROW — AND DECIDE
10 modules, 58 lessons

One bet, one bar written first, one date.
The hours-and-walls plan
A schedule you can keep, and the four walls checked against your contract.
The Sunday review
Thirty minutes: the sheet, one big thing, the calendar.
The replacement-number sheet

Every prompt, with how to judge it
Each exercise done with AI — the exact prompt, and what good and bad answers look like.
Deciding on a feeling, or deciding on the numbers. Same business. Different life.
08WHO THIS IS NOT FOR
Read this before you enroll.
✕ People looking for growth hacks or a dashboard. This is six numbers and honest decisions.
✕ People without paying customers yet. Start with the Income Course — there's nothing to measure until someone pays.
✕ People who want to be told to quit. The course teaches you how to decide, not what to decide.
If you're still here, you're exactly who this is for.
ENROLL
When can you quit the job?
Let the numbers say.
You don't finish this course with notes. You finish with a weekly sheet you trust, a week you can keep, the experiments that worked, your replacement number — and an honest call on when you can leave. Your business. Your numbers. Your decision, while you're still employed.

→AFTER THE COURSE
You'll have your number. Then comes the road.
BUILD is a loop: the next bet goes back to B. And the decisions ahead — raising prices, adding a segment, when to leave — are easier with people at your stage. That is what The Room is for.
→ A small room of founders who have already shipped.
→ Earn, decide, quit, scale — you never face the next stage alone.
→ By application.
?OBJECTION HANDLING · THE REAL OBJECTIONS
The questions you're already asking. Answered straight.
01I only have a few customers. Is there anything to measure?+
Yes — and that's who this course is for. With tens of customers you read people and reasons before percentages, and trends over weeks, not days. Six numbers are enough to steer by.
02Do I need analytics tools or a dashboard?+
No. One weekly sheet, counted by hand or with AI in ten minutes. The course is about reading numbers honestly, not collecting more of them.
03Will this tell me when to quit?+
It will tell you how to decide: your replacement number, coverage over three straight months, runway, and a readiness score. The decision stays yours — the course never tells you to quit.
04What about tax and my contract?+
The course names the questions to ask an accountant and what to check in your contract. It gives no tax, legal or career advice — those answers have to come from professionals who know your situation.
05Do I need the earlier courses first?+
It helps — this course picks up where the Launch Course ends. If you already have paying customers and people finding you, you can start here.
