Frequently asked questions
What if revenue is growing?
This simple model is deliberately conservative: it holds revenue and expenses constant. Use a monthly cash-flow model for hiring, seasonality, collections and fundraising scenarios.
What runway should a startup target?
There is no universal number. Match the buffer to sales cycles, payroll commitments, funding access and operating risk.
