Financial forecasting for startups – how to impress investors

A great financial model does more than show numbers – it tells a credible story about how your startup will grow.

Many founders treat financial forecasting as a fundraising exercise rather than a business tool. As a result, models often lack clear assumptions, realistic scenarios, and a strong link between the business story and the numbers.

In this session, Simon Ritchie, Founder and CEO of Blox, shares how founders can build investor-ready financial forecasts that support fundraising, guide decision-making, and create confidence in their growth plans.

By building a forecast that reflects how the business actually grows – and regularly using it to make decisions – founders can create stronger investor confidence, improve planning, and gain a clearer understanding of what it will take to achieve their goals.

Key takeaways

Investors back the story behind the numbers

• A financial forecast should explain how your startup plans to grow, not just present assumptions.
• The strongest models link revenue, pricing, acquisition, and retention to a clear growth narrative.
• Investors are assessing the thinking behind the numbers as much as the numbers themselves.

Forecasting is a business tool, not just a fundraising tool

• Great financial models help founders make decisions around hiring, spending, runway, and growth.
• Updating forecasts regularly keeps plans aligned with reality as the business evolves.
• The best founders use forecasting to run the business, not just raise capital.

Scenario planning reduces surprises

• Investors expect founders to understand both the opportunities and the risks ahead.
• Modelling different growth scenarios helps identify pressure points before they become problems.
• A well stress-tested forecast demonstrates preparedness and strategic thinking.

Credibility matters more than optimism

• Overly ambitious projections can damage confidence if they’re not backed by realistic assumptions.
• Investors want clear logic and evidence behind the numbers.
• A credible forecast builds trust and gives investors confidence in your plan for growth.
