Demo or product

Demos are built to survive four minutes in front of a friendly audience. Products are built to survive Tuesday. Here is how to tell which one you were shown.

What is on it

  • It was shown on the same three examples every time
  • Nobody typed anything unexpected during the demo
  • There is no visible behaviour for when the model is wrong
  • Errors are shown as a spinner that never resolves
  • There is no rate limit, so one user can spend everything
  • Nothing is logged, so nobody can tell you what happened
  • It has never run against a full copy of real data
  • The person who built it is the only one who can run it
  • There is no way to switch models if the provider fails
  • Nobody has written down what it is not allowed to do

Send it to me

Put your address in and the download appears on the next screen. A copy lands in your inbox too, so it is there when you need it again.

You also get the newsletter, every second Tuesday. Unsubscribe in one click.
