Our take
The popularity of being able to create fantasy teams and enjoy watching sports virtually has taken socialising around sports to a virtual level. In fact, the fantasy sports market size is expected to reach $48.6 billion by 2027. Sleeper was initially an app on which users discussed fantasy sports, but in 2017, it began hosting free fantasy football leagues, competing with sites like Yahoo. Integrating social media and sports, the company is now known to be one of the best DFS communities to hang out on.
A recent funding round means Sleeper can make plans to expand the game offerings on its platform and build a new feature called Wallet that will enable users to sync their preferred payment methods to the platform. There has been consistent growth for the platform since founding and it has successfully attracted a loyal user base.
