Which metrics matter before revenue
Before revenue, the question an investor asks is whether you reach paying customers before the cash runs out, so the numbers that matter are the ones that answer it. Retention, payback, and efficiency ratios need customers to measure. Computing them on no data gives you a precise-looking number that means nothing.
Start with runway and burn
Runway is the one number that matters from day one. Know your monthly burn, know how many months the bank balance covers, and know the date you need to raise again. Model the case where revenue arrives later than you hope, because it usually does.
Then the numbers that predict revenue
These start to mean something with a handful of design partners or trials.
- Pipeline: how many qualified conversations you have, and how many turned into trials or pilots.
- Win rate on those conversations, even with small counts, so you learn which buyers say yes.
- Price: what a buyer has agreed to pay, in writing, not what they said in a demo.
- Gross margin per customer, especially if each customer drives hosting or AI model costs.
What can wait
Net revenue retention, CAC payback, LTV to CAC, the magic number, and the Rule of 40 all need a revenue history. Start tracking them the month the first customer pays, with the definitions you will keep, and report them once there are enough quarters to show a trend.
Set the definitions now
The cheapest time to decide how you count ARR, a customer, or a churned account is before there is any. Write the definitions down, compute them the same way from the first dollar, and your first board pack will not need a footnote explaining why last quarter's number changed.
Key takeaways
- Runway and burn matter from day one.
- Pipeline, win rate, written price, and per-customer gross margin predict whether revenue arrives.
- Retention and efficiency ratios wait for a revenue history.
- Decide your definitions before the first customer pays.
Questions founders ask
- Should I show LTV to CAC to angel investors before revenue?
- No. With no customer history the inputs are guesses, and an experienced investor will discount the whole deck for it. Show runway, early pipeline, and what buyers have agreed to pay.
- When should I start computing ARR?
- The month the first subscription starts. Count only recurring subscription value, keep setup fees and services out, and use the same rule every month after.
