Sleeper is a fantasy sports platform that evolved from a popular social fantasy football app into a comprehensive pick'em and DFS platform. Originally focused on providing the best league management experience for season-long fantasy football, Sleeper expanded into the pick'em market, competing with PrizePicks and Underdog.
Sleeper's pick'em product allows users to project player stats over/under, with the advantage of being integrated into its massive existing user base of fantasy sports players. The platform covers NFL, NBA, MLB, and other major sports. Licensed in 25+ states, Sleeper is headquartered in San Francisco.
Editor's Verdict
Sleeper bridges season-long fantasy and quick-pick formats better than any competitor — the natural pick'em upgrade for the millions already using Sleeper for fantasy leagues.
