@regalstreak says they gave Jev 5,000 real user journeys and only each user’s first 3 journeys, hiding whether the user returned. In about 10 seconds and for $0.06, Jev predicted who would quit, how confident it was, and where each journey started going wrong.

We gave it 5000 real user journeys from a consumer app. It only saw each user’s first 3 journeys. We hid whether they ever came back. In around 10s, Jev predicted who would quit, how confident it was, and where each journey started going wrong. How Jev or TypeSafe is used, in the post's own words: “JEV IS INSANE.” The post does not name a separate audience. It is for people reading what @regalstreak shows here (it includes media).
