Dalton Caldwell: What does it really mean to do things that don't scale? Michael Sible: It seems like a lot of Founders get this confused. The term was massively popularized in a PGSA from 2013, but it was advice that he'd been giving YC Founders for a long time. He says when you think about something like food delivery, you imagine a scale-in, you want to be doing hundreds of orders a day. And so the way the founders got started was they just did all the deliveries themselves.
