In the SmartUp methodology, runway is directly tied to the principle that “Time is Money.” A company’s available time can be calculated with a simple formula, the amount of money in the bank divided by monthly expenses. This tells you exactly how long the company can survive before cash runs out.
SmartUp distinguishes between two fundamental states based on runway. A company that’s losing money is living on “borrowed time.” For example, if a company burns $1 million per year and has $3 million in the bank, it has exactly three years to live. Once the cash is gone, the company dies. But when a company reaches profitability, it enters the “Infinite Game.” Generate even slightly more cash than you spend, and your runway becomes indefinite. You’re no longer dependent on investors for survival.
Hiring has the greatest impact on runway. Salaries typically represent 70-80% of expenses in technology companies, and these costs are rigid. You can’t hire and fire employees month-to-month without major disruption. Every additional hire permanently increases monthly expenses and shortens runway.
For example, a company with $5 million in the bank and five employees might have six years of runway, a relatively safe zone. Grow that same company to 30 employees, and runway can shrink to just one year, pushing you into a desperate fundraising cycle.
The startup trap happens when companies raise capital and immediately scale headcount. This sharply increases burn rate, often reducing runway to less than a year and forcing founders to focus entirely on raising the next round instead of building a sustainable business.
