LOS ANGELES — Hype House, the physical location of a new content creator collective, is a Spanish-style mansion perched at the top of a hill on a gated street in Los Angeles. It has a palatial backyard, a pool and enormous kitchen, dining and living quarters.

Four of the group’s 19 members live in the house full time; several others keep rooms to crash in when they are in town. And all day long, a stream of influential young internet stars come by to pay homage to the new guard.
