Zhang Yiming, the co-founder and CEO of TikTok’s parent company ByteDance, is leaving the top job. He said he lacks “some of the skills that make an ideal manager” and that he’s (*irony alert) “not very social”. Taking his place will be fellow co-founder and HR head Rubo Liang, while Zhang will take on a different role in the company within the next 6 months. It’s the biggest change in leadership since the Chinese tech giant launched in 2012. The popular video-sharing app has blown up globally in recent years, boasting an estimated 700 million active monthly users. But its massive success has brought it under scrutiny from governments in both China and the West, with former US President Donald Trump threatening to ban the app last year amid national security concerns.
