StumbleUpon's Slogans & Taglines

StumbleUpon was founded in November 2001 by Garrett Camp, Geoff Smith, Justin LaFrance, and Eric Boyd at the University of Calgary, Canada. The platform pioneered personalised web content discovery, allowing users to click a "Stumble" button and be randomly directed to websites matched to their interests. By 2005, it had attracted over 500,000 users and Silicon Valley investment, leading to a relocation to San Francisco. In May 2007, eBay acquired the company for $75 million, but traffic plummeted under corporate ownership. In April 2009, the founders bought StumbleUpon back with investor support, restoring its startup spirit. At its peak, the platform served over 40 million users and generated nearly 60 billion stumbles, at one point driving more publisher traffic than YouTube, Reddit, and LinkedIn combined. In May 2018, StumbleUpon announced its closure after 16 years, transitioning user accounts to Mix.com.

The brand's core products were content discovery and recommendation services, including the StumbleUpon browser toolbar and plugin, StumbleVideo for video discovery, StumbleThru for navigating popular sites, and the Paid Discovery advertising platform used by over 100,000 publishers and brands.

From its founding mission to help people discover new webpages with a single click, StumbleUpon embraced the enduring slogan "Discover the Best of the Web." This promise reflected its journey from a dorm-room experiment to a global content discovery pioneer, ultimately paving the way for modern social media feeds and algorithmic recommendations.
