Financial Projections

Your financial model tells investors how you think about your business. A well-built model demonstrates strategic thinking, operational understanding, and realistic expectations. A poorly built model raises immediate red flags about your judgment and attention to detail.

Investors will scrutinize your projections, challenge your assumptions, and stress-test your scenarios. The best founders can defend every number in their model and explain the logic behind their projections. This guide walks you through building financial projections that will pass muster with investors.

A complete financial model for Series A includes several interconnected components. Each piece should tie together logically.

Revenue Model: Your projection of future revenue based on customer acquisition, pricing, and retention assumptions. Include MRR/ARR rollforward showing new customers, expansion, churn, and contraction.

Expense Model: Projections of all expenses organized by category: COGS, R&D, Sales & Marketing, G&A. Tie expenses to revenue drivers where possible.

Cash Flow Statement: Monthly cash flow from operations, investing, and financing. This shows your burn rate and runway.

Headcount Plan: Detailed staffing plan showing when you will hire each role and at what compensation level.

Scenario Analysis: Base case, optimistic case, and pessimistic case projections with clearly documented assumptions for each.

The best financial models are built from the bottom up, starting with fundamental business drivers. This approach is more credible than top-down market sizing.

Revenue Drivers:

- Number of customers (new, retained, churned)
- Average contract value or revenue per customer
- Customer retention and expansion rates
- Pricing and discount assumptions

Expense Drivers:

- Headcount by function and timing
- Sales and marketing spend as percentage of revenue
- Infrastructure costs scaling with usage
- Software and tool costs per employee

Why Bottom-Up Matters: Top-down projections like "we will capture 1% of a $10 billion market" are not credible. Bottom-up projections based on measurable drivers show you understand your business.

No one can predict the future with certainty. That is why scenario analysis is essential for credible financial projections.

Base Case: Your realistic expectation for performance. This should be achievable with good execution and normal market conditions. Investors will evaluate you against this case.

Upside Case: What happens if everything goes well. Stronger customer acquisition, higher retention, better pricing. This shows your ambition and what is possible.

Downside Case: What happens if things go wrong. Slower growth, increased churn, delayed hiring. This shows you understand risks and have contingency plans.

Key Assumptions Document: Create a separate document that lists every assumption in your model. Include the basis for each assumption and the range used in different scenarios.

Investors have seen thousands of financial models. They recognize common mistakes that signal inexperience or unrealistic thinking.

Revenue Growth Too Fast: Doubling or tripling revenue every year is not realistic for most businesses. Be realistic about market adoption and sales capacity.

Expenses That Do Not Scale: Models where expenses grow linearly while revenue grows exponentially. At scale, expenses typically grow faster than revenue initially.

Missing Driver Connections: Revenue and expenses that are not connected to each other. If you add sales people, you should show the revenue impact.

No Customer Acquisition Costs: A revenue model without customer acquisition costs is incomplete. Every customer has a cost to acquire.

Ignoring Churn: Many models assume customers last forever. Churn has a massive impact on long-term revenue and should be modeled explicitly.

Round Numbers: Revenue projections that end in clean numbers like $10M or $25M. Real revenue is messier and looks more credible.

How you present your financial model matters as much as the model itself. Follow these tips.

Create an Executive Summary: Most investors will not read every tab. Create a summary that highlights key metrics, assumptions, and scenarios.

Show Actuals vs. Plan: If you have been operating, show historical actuals compared to your projections. Variance analysis shows you understand your business.

Be Prepared for Questions: Know your model inside and out. Investors will ask "what if" questions—be ready to answer without looking at your notes.

Keep It Accessible: Use clear labels, consistent formatting, and logical flow. Your model should be navigable by someone who has never seen it before.

Document Everything: Include a assumptions document, instructions for use, and contact information for questions.
