Worth knowing

Sleeper's in-app chat is so good that many leagues use it as their primary group chat, replacing iMessage threads entirely.
ESPN Fantasy has been running since 1999, making it older than most of its current users.
Sleeper supports leagues up to 512 teams — large enough for an entire office building to join one league.
ESPN's expert roster (Matthew Berry era and beyond) gave it unmatched fantasy editorial clout for over a decade.
Sleeper launched in 2017 and quietly became the default platform for serious dynasty players within just a few years.

Sleeper's name is a fantasy football term for an underrated pick — and the app itself was basically a sleeper pick that blindsided ESPN without spending a dollar on ads.
