How to read it

  • < 6 months: emergency — start fundraising or cutting now.
  • 6–12 months: start raising; fundraises take 3–6 months.
  • 12–18 months: healthy. Average raise covers 18–24 months for most startups.
  • Default alive: Paul Graham’s term for the month when growth makes you profitable before cash runs out.
