Born in Punjab, Gurbaksh Chahal moved to the US at the age of three. When he was 16, he dropped out of school and founded ClickAgents, one of the first ad networks based on performance-based advertising. Eighteen months later, he sold the company to online ad company ValueClick for $40 million.
He started his second company in 2004, BlueLithium, again an online ad company, but one that depended on data, optimisation and analytics coming together to make money for advertisers based on behavioural targeting. Named as one of the top 100 private companies in the US for three years in a row, BlueLithium has also been named the Innovator of the Year along with Google, Skype and Salesforce.com. In 2007, Yahoo acquired it for $300 million. Now, Chahal is the Chairman and CEO of the third company he has founded, RadiumOne, another ad company that depended on real-time social interaction among people. Chahal has been profiled on everything from Forbes to the Oprah Show.
