❯ Former Dali Education CEO Chen Lin leaves ByteDance and builds an AI classroom product

A new education ventureEarly ByteDance employee and former Toutiao and Dali Education CEO Chen Lin addressed his departure from ByteDance publicly for the first time in an essay about returning to education as a founder. Citing corporate records on November 10, The Paper reported that Beijing Galaxy Intelligence Education was registered in late 2024 and is wholly owned by Chen. Its school-facing product is called Xiaolu Aixue.

Stepping back from DaliChen oversaw product work in ByteDance’s early years and took charge of Dali Education when it became a standalone brand in 2020. In his account, the business contracted in 2022 and health issues led him to step back. He spent about two and a half years recovering, during which he invested and advised some ByteDance departments. In the account reported by IT Home, Chen traced the idea to a rainy night at Sayram Lake in June 2023. As generative AI began reshaping professional work, he started thinking about how children could practice solving problems independently.

Schools and teachers are the entry pointGalaxy Intelligence Education positions Xiaolu Aixue as a classroom product. Students can ask questions, practice and correct mistakes at their own pace. The system connects their answers, mistakes and feedback so teachers can plan explanations or individual support. Adoption in classes, study periods and practice sessions depends on whether teachers can use that feedback in their regular work.
