As the team scrambled, Zhu took a brief gig at Microsoft driving its "mobile disruption" initiatives in the summer of 2014. bill gates microsoft antitrust suit Microsoft cofounder Bill Gates.

He noticed a group of teens nearby passing around their phones, half of them listening to music while the other half were taking photos and decorating them in emoji. alex zhu tiktok Before They Were Famous/YouTube Source: Business Insider Zhu thought about how he could combine these different features into a single social app for teens, and the idea for Musical.ly was born. The team behind Cicada turned Zhu's idea into an app in only 30 days, and in July 2014, launched Musical.ly for creating 15-second lip-syncing music videos.

"Combining Musical.ly and TikTok is a natural fit given the shared mission of both experiences — to create a community where everyone can be a creator," Zhu said at the time.

He then left ByteDance to take some time off to reportedly "rest, go clubbing in Shanghai and listen to jazz." He kept a low profile and stayed out of the media. alex zhu tiktok John Phillips/Getty Images for TechCrunch Source: Musical.ly, The New York Times Then, Zhu rejoined the TikTok team earlier this year, not long after ByteDance achieved a $75 billion valuation.
