Ehsan's Insight
Runway determines every strategic decision a startup makes, and most founders lie to themselves about how much they have. The standard calculation — cash ÷ monthly burn — assumes constant burn. In reality, burn increases as you hire, sign contracts, and invest in growth. Use a trailing 3-month average burn rate, not last month's burn, and add a 20% buffer for unexpected expenses. A founder who thinks they have 18 months of runway actually has 12. The minimum comfortable runway for any strategic initiative is 9 months: 3 months to build, 3 months to test, 3 months to pivot if it fails. If your initiative timeline exceeds your adjusted runway, raise money before starting. Running out of cash mid-initiative is worse than not starting.
