The Story Behind StumbleUpon

Before Uber, Garrett Camp founded StumbleUpon, a web-discovery platform designed to help people discover interesting websites.

The idea was different from traditional search engines. Instead of requiring users to know exactly what they wanted to search for, StumbleUpon could introduce them to websites based on their interests.

The platform became popular and attracted significant attention in the early internet era. Camp eventually sold StumbleUpon to eBay in 2007 for $75 million, giving him his first major entrepreneurial success.

The experience taught Camp important lessons about building online products and understanding how people interact with the internet.
