adbrite is the largest independent advertising exchange, focusing on display and video.
adbrite first started taking advertising for external sites in 2003, and raised $4 million in venture capital from Sequoia in September 2004 (Mark Kvamme joined the adbrite board of directors). In February 2006, adbrite raised another $8 million from Sequoia and Artis Capital, the same pair that invested together in YouTube. Two months later Philip Kaplan replaced himself as CEO, bringing in Shopping.com veteran Iggy Fanlo to run the show.
In 2008, adBrite changed its business model and became an ad exchange with site-level transparency. It also developed an open platform for data providers and real-time bidders to plug into.
adBrite now reaches 300 million global unique visitors every month, including more than 150 million in the U.S. Its services include adBrite Intelligence™, which provides real-time campaign reporting and analysis, and Audience Manager™, which leverages first- and third-party data for advanced targeting capabilities.
