Who This Helps
This is for product managers who have a dozen good ideas but need to know which one to test first. The Founder Finance Basics Mission Pack helps you cut through the noise. You’ll learn to build a one-page truth about your business so you can make calm, confident decisions.
Mini Case
Ben’s revenue was up 30% month-over-month, but his cash balance was flat. He was considering three experiments: a new onboarding flow, a pricing page redesign, and a referral program. By building a quick unit economics snapshot, he saw his average customer acquisition cost (CAC) had silently jumped from $45 to $68. The highest-impact move became instantly clear: fix the leaky acquisition bucket before adding new features. He paused the redesign and focused his next sprint on optimizing his top ad channel. It’s like finding the one wobbly table leg before you try to set the whole dinner party.
Do This Now (5 Steps)
- Grab your last month’s revenue and marketing spend numbers.
- Calculate your gross margin per customer. (Revenue per customer minus the direct cost to serve them).
- Calculate your simple CAC. (Total marketing spend divided by new customers acquired).
- Compare the two. Is your margin higher than your CAC? By how much?
- Frame your next experiment around improving that one key ratio. For example, if CAC is too high, your next test should aim to lower it.
Avoid These Traps
- Chasing Vanity Metrics: Don’t get distracted by session time or feature adoption if your core unit economics are broken. Revenue and cost per customer are your north stars.
- Analysis Paralysis: You don’t need perfect data. Use good-enough numbers from last month to make a directional call today.
- Ignoring Cash: It’s possible to grow revenue while burning unsustainable cash. Always connect your experiment back to its impact on cash flow.
- Building in the Dark: Launching a new pricing page without knowing your current payback period is like sailing without a compass.
- Overcomplicating the Model: Start with a simple snapshot on one page. You can add complexity later.
- Prioritizing by ‘Loudest Voice’: The CEO’s pet feature might not be what the business needs right now. Let the numbers guide you.
- Forgetting the ‘Why’: Every experiment should have a clear hypothesis tied to a business metric, not just a gut feeling.
- Skipping the Forecast: Don’t just look backward. Ask: ‘If this experiment works, how does it improve our runway forecast?’
