Break-Even Target
To become "Default Alive" (profitable) and stop burning cash, you need to increase your monthly revenue by $95,000 before your runway runs out.
The Clock is Ticking
For an early-stage startup, cash is oxygen. If you run out, the company dies. Monitoring your Cash Burn Rate and Runway is the most important fiduciary duty of a founder.
Gross Burn vs Net Burn
- Gross Burn: The total amount of money you spend in a month (Payroll, servers, rent). It ignores any revenue you make.
- Net Burn: The actual amount of cash you are losing every month. (Gross Burn - Revenue). This is the number that matters.
What is Runway?
Runway is the number of months your startup can survive if your revenue and expenses stay exactly the same.
Runway Formula = Total Cash in Bank / Monthly Net Burn
When to Raise Capital
Raising VC funding usually takes 3 to 6 months. Therefore, if your runway drops below 9 months, you are in the "Danger Zone" and lose all leverage in negotiations with investors. Most founders start preparing to raise their next round of funding when they have 12-15 months of runway left.
