How to Build a Business Model Slide That Holds Up

The business model slide answers a blunt question: how do you make money, and does the math work? Investors are not looking for perfection here. They are looking for evidence that you have thought past the product into the economics. Here is how to build one that holds up.

State how you charge in one line

Open with the mechanism in plain words: subscription, transaction fee, seat-based, usage-based, marketplace take rate. "We charge $499 per location per month" is instantly clear. Investors should never have to guess how revenue actually shows up.

Show the unit economics

The heart of this slide is a healthy unit: what it costs to acquire a customer (CAC), what that customer is worth over time (LTV), and how long until they pay back acquisition cost. An LTV-to-CAC ratio and a payback period in months tell investors whether growth will be profitable or a treadmill. Use real numbers if you have them, clearly labelled estimates if you are early.

Connect pricing to value

Pricing should map to the value you create, not just your costs. If you save a clinic 12 hours a week, $499 a month is easy to justify. Anchor your price against the cost of the problem, and the number feels small instead of large.

Address expansion

Investors love revenue that grows without new acquisition. If customers expand through more seats, more usage, or upsells, show your net revenue retention. A business where existing customers spend more each year is far more valuable than one that just replaces churn.

Keep it honest and simple

Do not invent five revenue streams to look bigger. Early companies win with one clear model executed well. Mention secondary streams briefly, but make the core model unmistakable. Complexity here reads as a lack of focus.

Tie it to the raise

The model slide sets up the ask. If your payback is nine months and CAC is falling, capital buys predictable growth. That logic turns "we want money" into "here is the engine your money fuels."

The test

After this slide an investor should believe two things: you know how you make money, and the economics can work at scale. If either is fuzzy, simplify and quantify until both are obvious.
