What is Default Dead?

Default dead is the uncomfortable truth for many startups: at your current trajectory, you will run out of money before your revenue covers your expenses. Something has to change — more funding, less spending, or faster growth.

Being default dead isn't a death sentence. Most venture-backed startups are default dead at some point. The danger is not knowing it, because that means you're not making the decisions needed to change the trajectory.

The calculation requires projecting your revenue growth forward and comparing it to your expense trajectory. If expenses still exceed revenue when your cash hits zero, you're default dead.

Why it matters

If you're default dead, you're fundraising from a position of weakness — you need the money, and investors know it. This affects your terms, your valuation, and your leverage.

More practically, knowing you're default dead forces you to make a plan: cut burn to extend runway, accelerate sales, or start fundraising immediately. The worst outcome is discovering you're default dead with only 3 months of runway left.

Example

You have $300,000 in cash, burn $60,000/month (5 months runway), and earn $10,000/month growing at 8% monthly. In 5 months, projected revenue = ~$14,700. Since $14,700 << $60,000, you're deeply default dead. You need to either raise capital or cut burn significantly.

  • 2Assuming a fundraise will close before you run out of cash without building in buffer time
  • 3Panicking instead of using the information to make a concrete plan
