What Investors Expect From a Startup Financial Model
What investors look for in a startup financial model: bottom-up revenue, a hiring plan, unit economics, runway, use of funds and honest scenarios.
Key takeaways
- Investors judge the reasoning, not the precision: bottom-up revenue, a matching hiring plan and clear unit economics.
- Show runway, use of funds and the milestones the raise is meant to reach.
- Build the model first and take the pitch deck's numbers from it so they always reconcile.
Investors do not expect a startup's forecast to be right. They expect it to be reasoned. A financial model for a raise is a way of showing how the founders think about the business: what drives revenue, what it costs to grow, how long the money lasts and what it will have achieved by the time it runs out.
Bottom-up revenue
A top-down forecast says the market is worth a large sum and the company will capture a small percentage. A bottom-up forecast says how many customers can be reached through each channel, what it costs to reach them, how many convert and what they pay. Investors trust the second kind because every step can be challenged and tested against early data.
A hiring plan that matches the growth
Headcount is usually the largest cost. The model should list roles by month with salaries and on-costs, and the plan should be consistent with the revenue forecast: a sales target needs the salespeople to deliver it, and they need time to become productive.
Unit economics
Show what it costs to win a customer, what that customer is worth and how long it takes to earn the acquisition cost back. For subscription businesses the specific metrics are covered in SaaS financial model metrics.
Runway and use of funds
- Monthly cash burn and the month in which cash runs out without new funding.
- How much is being raised and how it will be spent, by category.
- The milestones the raise is intended to reach, and the month each is expected.
- Enough headroom beyond the milestone to complete the next raise.
Scenarios
One forecast is a single opinion. Investors want to see a base case, a downside in which growth is slower or costs are higher, and what management would do in that downside. A model in which every scenario still reaches profitability is less convincing than one that shows where the risks are.
Structure and presentation
- Monthly for the first 24 months, then quarterly or annual to three or five years.
- All assumptions on one sheet, clearly labelled and easy to change.
- Income statement, cash flow and balance sheet that tie together - see how the three statements link.
- A one-page summary of the key figures an investor will ask for.
Numbers that match the deck
The fastest way to lose credibility is for the pitch deck to quote figures the model does not produce. Build the model first and take the deck's numbers from it. That is the principle behind our startup financial models, and why our pitch decks and business plans are built on top of the model rather than alongside it.
Frequently asked questions
How many years should a startup financial model cover?
Three to five years, with at least the first 24 months monthly. Investors focus most on the period the current raise will fund and on the path to the next milestone.
Do pre-revenue startups need a financial model?
Yes, though a simpler one. It should show the costs of reaching the next milestone, the runway the raise provides and the assumptions about how and when revenue starts.
What is the most common mistake in startup financial models?
Revenue growth that is not connected to the spending needed to achieve it. Customer numbers rise while sales and marketing costs stay flat, which investors notice immediately.
