Original Summary

I put something out on another startup sub recently and ended up with around 50 founders in my DMs in a single day. I asked almost all of them the same four questions. The answers were so consistent that I think it's worth writing down. The four questions What does it cost you to get one paying customer, not one signup? What does that customer pay you per month? How many months until you get your money back? What percent of them are still here at month 12? Nine people out of fifty could answer all four. Not nine percent of a big sample, nine actual humans. Most could answer question 2 instantly and went quiet on the rest. What people answered instead "Our CAC is low because we're mostly organic." That is not a CAC, that is an absence of measurement. Your time is the cost and it is the most expensive input you have. "We're at 2.4 ROAS." On a subscription product this means close to nothing. ROAS compresses a 14 month relationship into a 7 day attribution window. You are measuring the first payment of a contract and calling it the contract. "Signups are up 40 percent." I asked how many activated. Silence. Signups are the cheapest metric to move and the least connected to revenue. If your onboarding loses 70 percent before first value, doubling signups doubles the size of the leak. "We'll figure out pricing later." Pricing is not a later problem, it is the denominator of every other number. You cannot know if a 60 dollar CAC is good or suicidal until you know if the plan is 9 dollars or 90. Why question 3 is the one that matters Payback period is where product, pricing and acquisition collide, and it is the only number that tells you whether you can actually scale or whether scaling kills you. Simple version. You spend 300 to acquire a customer paying 50 a month. Payback is 6 months. That is fine if you have 12 months of runway and brutal if you have 4, because every new customer makes your cash position worse before it makes it better. Growth and solvency pull in opposite directions and most founders discover this at the exact moment they cannot afford to. The founders who knew their payback had something in common. They were not smarter, they just had fewer metrics. Four numbers tracked properly beats a dashboard with forty. The minimum viable version You do not need attribution software for this. A spreadsheet works. Total spend last month, including your own time at a realistic rate, divided by new paying customers. That is your real cost per customer. Average monthly revenue per customer, after payment fees and hosting. Divide one by the other. That is payback in months. Count how many customers from 12 months ago are still paying. That is retention, and it decides whether the first three numbers mean anything. Thirty minutes of work. If the result scares you, that is the point. It was scaring you before, you just could not see it. One pattern I did not expect The founders with the cleanes
