Jack Schwartz, a 21-year-old former Los Angeles teenager, has turned high-school "after-prom" parties into a lucrative business through MyPlots, a party promotion and ticketing app he founded after gaining a reputation for throwing elaborate ragers from the age of 14. Launched in January 2025, the app has become the dominant platform for under-21s organising and attending parties in LA, illustrating how teenage social events have evolved from informal rites of passage into full-fledged commercial enterprises with real money and marketing muscle behind them.

MyPlots now has more than a million users and is expanding beyond teenagers into older, of-age crowds, having overtaken rivals such as Partiful as the go-to app among LA promoters over the past year. Hosts create events and sell tickets through the app, with MyPlots taking a 20 percent cut, though it requires users to be 18 in principle, enforcement is loose, and Stripe integration allows account holders as young as 13 with a parent attached. Events listed on the platform range from an all-ages rap show to mansion parties advertising celebrity guests and tiered, sometimes gender-based, ticket pricing — with other promoters, including 310 Events and Off Campus Events, also competing in this increasingly commercialised teen-party market.
