Gurbaksh Singh Chahal (born July 17, 1982) is an Indian-American internet entrepreneur and writer, who has also been convicted of domestic violence.
By the age of 25, Chahal had founded two start-up advertising firms that sold for a total of US$340 million. From 2014 to 2016, Chahal was on probation for domestic violence battery and battery, but a court revoked his probation after evidence emerged of a second domestic violence incident, which would violate his probation. In August 2016, he was sentenced to 1 year in jail  for violating probation and has stepped down as CEO of Gravity4, the second time he has left a CEO post following domestic violence allegations.
Chahal dropped out of high school at age 16 to work full-time at his first venture, ClickAgents. ClickAgents was an advertising network focused on performance-based advertising. Two years later, ValueClick announced it agreed to buy ClickAgents in a $22 million all-stock merger.
In 2004, Chahal formed BlueLithium, a company that 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). In 2007, Yahoo! bought Blue Lithium for $300 million in cash. Chahal remained CEO of the company through the transition period.
In 2009, Chahal started RadiumOne, an online ad company that focused on creating a new category of real-time advertising. 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. In July 2016, Chahal gave his position as CEO of Gravity4 to his sister Kamal Kaur after a judge ruled that he violated his domestic violence probation by assaulting another woman in September 2014.
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 30-minute 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.
Chahal, at the urging of RadiumOne investor and one-time California state controller Steve Westly, paid former San Francisco mayor Willie Brown a $250,000 retainer to keep the charges from derailing a planned $100M IPO. Chahal met with and engaged Brown after Westly suggested that Brown could take advantage of his connections to the district attorney's office. After the Judge's favorable ruling regarding the admissibility of Chahal's video, Brown returned $198,400.
On April 16, 2014, following a plea bargain, Chahal pleaded 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 July 2016, a San Francisco court revoked Chahal's probation after evidence of an additional domestic violence incident emerged. 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. In addition, prosecutors alleged that Chahal's security guard attempted to intimidate the victim by visiting her shortly after the incident to discuss her immigration status; she later returned to South Korea. As of July 2016, Chahal is awaiting sentencing for violating probation.
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.
