I ve been building FFCC, a financial command center for SaaS founders, and one thing keeps standing out: runway is often treated as a static number.

But the real decision is usually:

• When should fundraising start?

• How much capital is actually needed?

• What happens if growth slows or churn increases?

• How long does the next round protect the business?

I m building the model around these decisions rather than just reporting metrics.
