RadiumOne is an advertising platform which covers online, video, social and mobile advertising using real-time bidding. It was first launched in 2009 by Gurbaksh Chahal. The company was initially known as gWallet, a loyalty and rewards program. As of 2014 the company was listed as the "ninth largest online ad network" by ComScore.
After CEO Gurbaksh Chahal pleaded guilty to domestic violence battery on April 23, 2014, there were calls for him to step down as CEO. He was fired on April 27,  and TechCrunch Disrupt dropped RadiumOne as a sponsor of the event.
The company utilizes data taken from social networking sites such as Twitter and Facebook and tailors advertisements for the consumer. It was one of the first companies to use real-time social data in such a manner.
