Spent an hour this morning convincing a CEO to take $1,000 and burn it today instead of over the next week. If his CAC and payback period stats are real, he'll have his money back tomorrow morning.
Here's what we're working from:
On his recent tests, $10 in marketing returned $75 in spend, of which he got 15% in pure profit. The machine was functionally running breakeven.
So I asked him about payback period. He asks, "What do you mean?"
I'm like, dude, from the time you acquire them to the time you get a wire from Stripe — how long does that take?
"I don't know. Five minutes?"
Five. Minutes.
So why are you telling me you're spending a thousand bucks this week on advertising? Why aren't you spending a thousand bucks today? Because based on your numbers, you'll have your money back tonight. Spend that $1,000 again tomorrow. Get $1,000 back tomorrow night. If that still works, spend $2,000 Wednesday.
If the math holds, you're playing with house money.
And he's out trying to raise capital to fund this.
Here's the thing every founder pitching a paid acquisition story needs to internalize. Any investor with a marginally functional brain is going to ask one question: have you tested this at a growing spend for a sustained period?
If the answer is "no, I ran it once and extrapolated" — those are bullshit numbers. And the investor knows it.
The proof isn't a deck slide. The proof is showing you spent $1K on Monday, $2K on Wednesday, $4K on Friday, and the LTV/CAC held the whole way. That's the test investors are going to run on your numbers anyway. Do it yourself first.
If the loop works, you don't need their money for the spend. You need their money to pour gasoline on a fire that's already burning.
If the loop doesn't work, better you find out for $2,000 than for $2 million.
He's spending $1,000 today. We'll see what comes back tomorrow.
