StumbleUpon: Web Discovery Platform

Web discovery platform that recommends web content based on user ratings and collaborative filtering, suggesting interesting websites and articles matching users' interests.

What is StumbleUpon?

StumbleUpon is a web discovery and recommendation platform launched in 2001. It allows users to discover and rate websites, articles, images, and videos that match their interests. StumbleUpon uses collaborative filtering technology to analyze the ratings and preferences of its community and recommend relevant content to each user.

Users start by selecting topics of interest when they sign up for an account. As they browse the web through StumbleUpon, they can give a “thumbs up” or “thumbs down” to the pages shown to them. These ratings teach StumbleUpon about their likes and dislikes. Over time, its recommendation engine gets better at matching users to interesting content.

StumbleUpon works across all major browsers as a browser toolbar addon. The toolbar shows a Stumble! button that users can click to be taken to a random web page suited to their preferences. There are also StumbleUpon mobile apps for iOS and Android devices to discover content on the go.

As of 2016, StumbleUpon has over 40 billion user ratings across 5 billion web pages. Its community of over 25 million users stumbles across over 1 billion web pages per month. The service is freemium, offering ad-supported free access along with paid pro accounts with additional features.
