TikTok is considering Instagram billionaire Kevin Systrom, who left Facebook in 2018, to fill its vacant CEO position. The discussions are only in the early stages. If Systrom joins TikTok, the firm would get someone immensely familiar with its rival – Facebook. Systrom sold Instagram to Zuckerberg in 2012 for almost $1B and then built it up to over 500M users before leaving. TikTok’s last CEO Kevin Mayer quit the company only after a few months of service.
