What is startup runway?
Runway is the number of months your company can keep operating before it runs out of money, assuming your income and spending stay roughly the same. The formula is simple — cash ÷ (monthly expenses − monthly revenue) — but it's the single most important number a founder tracks, because it's the countdown clock behind every hire, every ad spend, and every fundraising decision.
How much runway should you have?
Most investors want to see 12–18 months of runway after a raise so you have time to hit the milestones that unlock the next round. Dipping under six months is a red flag: you're now raising, cutting burn, or growing revenue under pressure. If you're heading into a raise, a longer runway gives you leverage to say no to a bad term sheet.
