Frequently asked questions
How much runway is safe?
Eighteen months after a raise is the classic target. Under 12 means fundraising or profitability moves start now, not later.
What counts as burn?
Net monthly cash outflow: all spend minus collected revenue, not booked ARR. The tool uses net burn so the answer is honest.
Can I model a hire?
Yes. Add monthly cost per hire and see the new zero-cash date instantly.
