Former Feishu Vice President quits his startup after less than three months; Shi Kaiwen is reportedly joining Jieyue to lead Agent OS.

Beating AI Express (from Dongcha) reports that former Feishu Vice President of Product Shi Kaiwen has been revealed to have joined StepChips as a partner, reporting directly to Chairman Yin Qi, and is responsible for the Agent Operating System (Agent OS) segment. The news first emerged in mid-September, with the original report later removed, and StepChips has not publicly confirmed the development to date. Shi Kaiwen left Feishu at the end of June this year to start a business focused on edge-side Agents, with his team members hailing from ByteDance and Shanghai Jiao Tong University. Sequoia China and Jinqiu Fund were once reported to have participated in the project’s early-stage investment, with the startup rumored to be valued at up to $500 million. However, less than three months later, media outlets disclosed that he had called off the venture and instead opted to join a large language model (LLM) company. In January this year, Yin Qi took office as Chairman of StepChips; in July, StepChips launched its Agent Operating System Step AOS, personal agent Amoo, and the STEPX Neo smartphone; the device officially went on sale in October, priced at 3,999 yuan. Shi Kaiwen previously played a key role in developing Feishu’s multi-dimensional spreadsheet, and is adept at translating complex enterprise collaboration capabilities into user-friendly products for ordinary consumers. Now, he may bring this expertise to the smartphone Agent space, enabling AI to progress from understanding commands to executing actual operations.
