Platform for generating and distributing high-quality, targeted discussions (called posts) that increase revenue and engagement for online content publishers, offering them a superior option to Outbrain (about to IPO), Taboola, and Disqus.
Sidelines' posts reach 10M+ unique readers (growing >100% m/m since October) through publishers, increasing average time spent on their sites by 2.1x. Sidelines earns > $40 per post by promoting brands, sharing a cut of the revenue with the publishers who distribute the posts, indicating a potential revenue of ~$100M/yr at scale, with a 75% net margin.
Sidelines has started with sports, and is expanding to other content verticals starting with Gaming, followed by Fashion, Lifestyle, and Music.
Posts are created by a community of 500+ contributors, and Sidelines’ tech matches posts up with relevant articles on its publishers' sites. Sidelines' proprietary Reputation algorithm keeps the quality of posts high by weeding out poor content.
