Chen Xi, head of ByteDance-owned news aggregation app Jinri Toutiao, will leave his current position and lead product and data science for TikTok’s e-commerce department, Chinese media outlet LatePost reported on Tuesday. TikTok is struggling to replicate its model of commercial success beyond China. Zhang Chao, head of the free novel app Tomato Novel, will take over the vacancy left by Chen Xi, aiming to push interconnectivity across all Douyin-related products, including Douyin, Xigua Video, Jinri Toutiao, and Tomato Novel.
