If you are pre-revenue, project core KPIs (users, pilots) instead of making up revenue numbers.
Your Financials Are a Test of Your Thinking
No seed investor believes your five-year financial projections. Everyone knows they are a work of fiction. So why are they one of the most important slides in your deck?
Because your projections aren't a math test. They are a test of your ability to think like a CEO. They reveal whether you truly understand the cause-and-effect relationships that drive your business. They tell the story of your business in the language of numbers.
Investors aren't looking for a perfect forecast. They are looking for a founder who has a credible theory of how to build a venture-scale business. The financial slides are where you prove you have one.
The Only Way to Forecast: Bottom-Up
The single biggest mistake that kills a founder's credibility is a "top-down" forecast. It sounds like this:
"The global market for our product is $50 billion. We project capturing just 1% of that, which will make us a $500 million company."
This is an instant red flag. It tells investors you have no actionable plan for acquiring customers. You must build a "bottom-up" forecast, starting with the drivers you can actually control.
A bottom-up model starts with your unit-level plan and builds from there. You aren't guessing market share; you are modeling the specific actions you will take to generate revenue.
Example: Bottom-Up SaaS Forecast
You don’t start with market size; you start with your go-to-market motion. Every step is a lever you can pull and an assumption you can defend.
