Jaffer was charged with a slew of felonies in October of 2017, including sexually assaulting his 3-year-old son and attacking a police officer.
Stephen Wagstaffe, San Mateo County district attorney, previously suggested that Jaffer was perhaps on LSD, but later said in a statement that, "We do not believe that there was any sexual conduct by Mr. Jaffer that evening and for this reason we dismissed the sexual abuse charges. The physical injury charges were separately dismissed because we believe that the injuries were the result of Mr. Jaffer being in a state of unconsciousness caused by prescription medication."
It is not clear what prescribed medication Jaffer had consumed, but San Mateo County officials said in a statement that Jaffer "did not do anything whatsoever that could be considered sexual," adding that he also suffered from an "adverse reaction to medication and in the process injured some family members."
Vungle captured widespread interest from investors after it was featured as Slide No. 27 of 355 in Mary Meeker's 2017 Internet Trends report.
Vungle is a successful platform that specializes in creating custom-tailored ads using brands' first-party data to get consumers to download and install apps. Meeker used Vungle as an example of how dynamic ad creation can increase conversion rates.
The company has a roster of clients that includes Coca-Cola, the NFL, P&G, Unilever, Electronic Arts, L'Oréal, Warner Bros., Sega, Zynga, among many other well-known brands.
Jaffer previously told Ad Age that Vungle has a $300 million run rate and "plenty of cash in the bank."
Patrick Clancy, attorney for Jaffer, said the former ad tech CEO is hopeful he will be able to return to his post as chief executive at Vungle.
