ByteDance has integrated its enterprise collaboration unit into other teams, sharpening its focus on using artificial intelligence to serve corporate clients as annualised AI revenue of US$4 billion pushes it to the front of the pack in China, according to sources. The Beijing-based company decided to integrate the product team of office tool Lark, known as Feishu domestically, into the product team in charge of the Doubao AI chatbot, according to an internal memo seen by the South China Morning Post on Thursday. The new bigger section would be led by Zhao Qi, who previously oversaw Doubao only, while David Xie Xin, the CEO of the Lark unit, would report to Zhao. Meanwhile, Lark’s sales, marketing and customer services personnel would merge with a team under the cloud unit Volcano Engine, establishing a new department responsible for sales and customer service for the firm’s model-as-a-service and software-as-a-service offerings, as well as other cloud services. Tan Dai, the president of Volcano Engine, would take over the new team. Similarly, Lark’s development and infrastructure team would be merged into Flow, a division that focuses on AI applications. ByteDance said the moves aimed to build “stronger AI product competitiveness and customer service capabilities”.
