Frequently Asked Questions
What is startup runway?
Runway is the number of months a company can continue operating before it runs out of cash, based on current cash reserves and net monthly burn rate (expenses minus revenue).
How is burn rate different from net burn?
Gross burn is total monthly spending, while net burn subtracts incoming revenue from that spending — net burn is what actually depletes your cash balance.
How much runway should a startup have?
Most investors recommend maintaining at least 12-18 months of runway to give enough time to hit milestones and raise the next round of funding.
