ByteDance ships Feishu 8.0 and Doubao Work Partner as office collaboration enters the agent era

ByteDance used the 2026 Feishu Future Unlimited Conference and Doubao Work Kickoff event to launch two products at once: Feishu 8.0 and Doubao Work Partner. One is positioned as a collaboration platform built for both agents and people, the other as a team-facing enterprise agent, and both come from inside ByteDance.

The core of Feishu 8.0 is a systematic redesign for agents. Until now collaboration software was designed for humans, but when people and AI work side by side the platform itself has to be designed for agents too — pulling them into group chats, writing documents, operating spreadsheets and running approvals are now all things an agent can do.

In practice, a company can add an agent to a chat the way it adds a colleague and assign work with an @ mention. Multiple agents can @ each other and complete tasks together without a human relaying messages; slash commands bring an agent up quickly, and Markdown or HTML produced by AI can be edited directly inside Feishu instead of being exported to another piece of software.

Permissions and control are the other half of the release. An agent’s rights inside Feishu always match those of the person using it, so information an employee cannot see is also invisible to the agent, and administrators can manage agents centrally, trace usage, set AI spending caps and restrict expensive models or scenarios. Bitable and the Feishu project tooling were upgraded along the same lines.

Doubao Work Partner extends the assistant from an individual to an entire team. It has its own organisational identity, can be pulled into group chats, follow discussions, join meetings and read documents and code, and is expected to push work forward on its own; the report compares it to Anthropic’s Claude Tag, which debuted in Slack in June.

ByteDance CEO Liang Rubo used the stage to set out the company’s view of productivity in the AI era: agents do not exist in isolation and must collaborate with people, with the working environment and with other agents, and agents, models and the collaboration environment have to be tightly fused. On that basis ByteDance restructured, bringing Doubao, Feishu and Volcano Engine together around work and productivity products.

The commercial signals are equally direct. Feishu’s ARR growth in the first half of 2026 was 2.5 times the year-earlier rate, more than 90% of new customers also bought AI products, and over 40% of new customers named agent-native support as a core selection criterion. Large companies such as SAIC, Starbucks, Guqin and Air China — long-time users of established collaboration suites — are moving to Feishu on the strength of that new AI standard.

The wider significance is that the next stage of collaboration has moved from concept to product shape: agents are no longer add-on assistants bolted onto office software but are designed for as members of the organisation, with their own identity, permissions and workflows. What to watch next is whether native team agents can deliver reliably inside messy real corporate processes, and whether security and cost control become the decisive purchasing thresholds.
