Who This Helps
This is for you, the founder operator who feels like every experiment is urgent. You have three ideas for growth, but only one week of cash to test them. You need a fast, evidence-based way to pick the winner.
Mini Case
Meet Ben. His revenue is up 12% this quarter, but his cash balance is flat. He has three experiments: a new pricing tier, a Facebook ad channel, and a referral program. Using the Founder Finance Basics Mission Pack, Ben runs a quick unit economics snapshot. He discovers his CAC payback period is 7 days on referrals, 30 days on ads, and 45 days on the new tier. The referral program wins. He focuses his next sprint there and sees a 20% lift in repeat orders.
Do This Now (5 Steps)
- Grab your last 3 months of revenue and cost data. You need total sales, number of customers, and marketing spend.
- Calculate your unit economics. Divide revenue by customers to get average revenue per customer. Divide marketing spend by new customers to get CAC.
- Find your payback period. Divide CAC by monthly profit per customer. If payback is under 30 days, that channel is safe.
- List your top 3 experiments. Write down the expected CAC and payback for each. Use your real numbers, not guesses.
- Pick the experiment with the shortest payback. That's your highest-impact move this week.
Avoid These Traps
- Don't use average revenue for everyone. Segment by channel or customer type. One bad channel can hide a good one.
- Don't ignore cash timing. A 45-day payback might be fine if you have 6 months of runway, but risky if you have 2 weeks.
- Don't run 3 experiments at once. You won't know which one worked. Pick one, test it hard, then move on.
- Don't forget to include your own time. If an experiment takes you 10 hours a week, that's a cost too.
Your Win by Friday
By Friday, you will have a single experiment to run. You'll know exactly why it's the best bet. No more decision paralysis. Just one clear move that improves your unit economics. And maybe a little extra cash in the bank for next month's coffee run.
