More from Elad Gil, Sam Altman

Short answer

Elad Gil defines a startup miracle as the key difficult thing you need to pull off for the startup to work, like reaching product-market fit, landing a key deal or a regulatory change. If you need zero miracles, the startup probably isn't defensible. If you need several, it probably won't work, because each one multiplies in another low-probability event.

Zero, one or many

Sam Altman puts it the same way in his startup advice: "Startups should require as few miracles as possible, but at least one."

  • Zero miracles: probably not a defensible startup.
  • One miracle: the one hard thing that, once done, makes the company work.
  • Several miracles: probably won't work. In Elad Gil's words, "with every miracle, you are multiplying in another low probability event".

Examples of a miracle

  • Reaching product-market fit.
  • Landing a key business deal.
  • A specific regulatory change.
