Who This Helps
You're a growth marketer who wants to move channel metrics without guesswork. You have data, but you're not sure which lever to pull first. This is for you.
Mini Case
Meet Ben. He runs growth at a SaaS startup. Revenue is up 20% month over month, but cash is flat. He's confused. He runs the Unit Economics Snapshot from the Founder Finance Basics Mission Pack. He finds his CAC is 12% higher than last quarter, and payback stretched from 7 days to 14 days. Now he knows: the next experiment must fix CAC, not volume.
Do This Now (5 Steps)
- Pull your unit economics. Grab your revenue per customer and cost per acquisition for the last 3 months.
- Calculate CAC payback. Divide your CAC by monthly gross profit per customer. If it's over 12 months, you're in the danger zone.
- Rank channels by payback. List your top 3 channels. Sort them from shortest to longest payback period.
- Pick the worst performer. The channel with the longest payback is your next experiment target.
- Design one move. Example: cut spend on that channel by 20% and test a new audience segment. Run it for 2 weeks.
Avoid These Traps
- Don't optimize for revenue alone. A channel with high revenue but long payback can kill your runway.
- Don't run 5 experiments at once. You won't know what moved the needle.
- Don't ignore fixed costs. They eat your margin faster than you think.
- Don't trust averages. Look at channel-level data, not company-wide numbers.
Your Win by Friday
By Friday, you'll have one clear experiment: the channel with the longest CAC payback. You'll know exactly what to change and why. No more guessing. Just a calm, data-backed move.
And hey, if Ben can do it while keeping his cash flat, you can too.
