Frequently asked questions
Quick answers before you start.
What is a healthy runway for a startup?
Most investors expect 12–18 months of runway. In practice, 6 months is the point where you should already be cutting costs or closing revenue. Under 3 months is urgent — act before you're forced to.
What should I include in my monthly burn?
Everything the company spends: salaries, rent, tools, marketing, cloud, and contractor payments. Subtract any revenue. Most founders underestimate burn by forgetting annual payments and small recurring subscriptions.
How do I extend my runway?
Cut costs first — it's the fastest lever. Then accelerate revenue: raise prices, close faster, or add a retainer model. Revenue is slower than cost-cutting, so don't wait until the last months to start.
