Ranker is a Top 50 destination for crowdsourced rankings on everything from films to food. We believe that the opinion of millions is more relevant (and far more predictive) than the opinion of one critic. Ranker consistently delivers 50 million worldwide unique visitors and outranks nearly every consumer site in minutes spent per visit according to comScore (4.5 mins per visit). Visitor engagement is the center of Ranker, which collects over 15 million monthly votes across more than 100K lists including extremely competitive searches like “best movies of all time” (which has over 4.3MM votes alone). Based in the heart of Los Angeles, the company is solidly profitable and has 90+ employees and growing.

Ranker is now expanding building offshoot products in both the B2B and B2C space, while continuing to grow its core media business. More than 650MM consumer votes have built Ranker Insights, a treasure trove of psychographic correlation data ("people who like X also like Y"). Ranker Insights provides data-driven audience insights to marketers, studios, and platforms seeking a deeper understanding of consumer tastes and preferences. Ranker has just built a new “WatchWorthy” app (prototype here) powered by these correlations.
