Chango

Founded in 2008 in Toronto, Canada, Chango was a prominent ad-tech company that pioneered intent-based marketing. The company developed a proprietary platform for programmatic advertising, enabling marketers to target consumers with display ads based on their recent online searches and site visits. Chango's technology was designed to create more relevant and effective advertising campaigns. In December 2014, it was announced that Chango would be acquired by Rubicon Project for approximately $122 million, an acquisition that was completed in early 2015. The company's technology and team were integrated into Rubicon Project, which later merged with Telaria to become Magnite.
