Gurbaksh Singh Chahal (born July 17, 1982) is an Indian-American internet entrepreneur and writer. By the age of 25, he founded and sold two advertising companies for a total of US$340 million. Chahal is currently on probation for domestic violence battery and battery.
Chahal was born in Tarn Taran Sahib in Punjab, India to Avtar Singh and Arjinder Chahal. Chahal has 1 brother and 2 sisters. In 1985, his parents received a visa for America through the Diversity Immigrant Visa program, also known as the Green Card Lottery, and the following year, when he was four, the family settled in San Jose, California.
On December 15, 1998, aged 16, Gurbaksh Chahal dropped out of high school to work full-time at his first venture, ClickAgents. ClickAgents was an advertising network focused on performance-based advertising. Two years later, on November 1, 2000, ValueClick announced it agreed to buy ClickAgents in a $22 million all-stock merger. Chahal had a three year non-compete agreement with ValueClick.
On January 12, 2004, Chahal formed BlueLithium. BlueLithium specialized in behavioral targeting of banner advertising (a process that tracks web users' habits online in order to show ads they are most likely to respond to). The advertising network which was recognized as an innovator in the online advertising space in a Business 2.0 article. In 2006, under Chahal's leadership, BlueLithium was named Top Innovator by AlwaysOn.
In September 2009, Chahal started his third online ad company, focused on creating a new category of real-time advertising. On December 1, 2009, it raised its first institutional round of financing totaling $12.5 million from Adam Street Partners, Trinity Ventures, Stanford University and various others. On October 18, 2010, a few days after Chahal's non-compete expired, the Company re-branded itself as RadiumOne, and launched its Programmatic Advertising Platform that leverages first party data to deliver real-time advertising across the web, including mobile and Facebook. In March 2011, RadiumOne announced it had raised another $21 million in financing which valued the Company at $200 million. On March 2, 2012, RadiumOne's valuation surpassed $500 million. Chahal was fired as CEO of RadiumOne by the company's board of directors on April 27, 2014, after pleading guilty to a domestic violence battery charge and rejecting calls to step down voluntarily.
In July 2014, Chahal launched his fourth technology company in online advertising, named Gravity4. In April 2015 a former female employee from Gravity4 filed suit against Chahal and the company for gender discrimination and harassment.
Chahal currently lives in San Francisco, California.
On April 29, 2010, Chahal was awarded the Leaders In Management Award and an honorary degree in Commercial Science from Pace University for his career achievements as an entrepreneur. In April 2011, Men's Health recognized Chahal as one of the world's "richest and fittest guys".
Domestic violence conviction
In August 2013, Chahal was charged by the San Francisco District Attorney's Office with 47 counts of domestic violence. Prosecutors alleged Chahal "hit and kicked" his girlfriend 117 times over a half-hour period on August 5, 2013. Chahal’s video security system included cameras throughout the apartment, including two in the bedroom where the attack occurred. Chahal pleaded not guilty to the charges and posted $1 million bail.
The prosecution's case was set back because the victim refused to cooperate with the prosecution. On April 2, 2014, a judge ruled that the video the SFPD obtained from Chahal's apartment could not be used as evidence in his trial because police had seized it without a warrant, leading the prosecution to drop felony charges.
On April 16, 2014, following a plea bargain, Chahal pled guilty to one charge of domestic violence battery and one charge of battery. Chahal was sentenced to three years probation, a 52-week domestic violence training course, and 25 hours of community service. 
After his conviction, Chahal tweeted, "I maintain my innocence regarding these exaggerated accusations"; "For the past 10 months there were overblown allegations against me because of my alleged high-profile status"; and "Is the Internet this stupid to read one side of the story by tabloids vs. the actual truth? Grow up people before u judge false accusations." Chahal later deleted the tweets.
In May 2015, the San Francisco District Attorney's office sought to revoke Chahal's probation because he allegedly repeatedly kicked a girlfriend in the leg during an argument and threatened to report her to immigration authorities. The girlfriend accused Chahal of being violent with her in the past, grabbing her by the hair and once bruising her wrist during arguments.
Inspired by the deadly events relating to the Wisconsin Sikh temple shooting, Chahal founded the Chahal Foundation with $1 million of his own money. The foundation is designed to create awareness campaigns to stop future hate crimes, scholarships, supporting disaster relief efforts, and improving school in third world countries.
