Origin
Feishu's story began in late 2016 under the internal code name Lark, initially serving solely as a collaboration tool for ByteDance employees to manage documents, schedules, and meetings. The core driving force behind ByteDance's decision to build it in-house was that existing collaboration products on the market could not meet the internal communication and knowledge management demands driven by its rapid expansion. It first served tens of thousands of ByteDance employees, refining the product through high-frequency internal usage before being pushed to the external enterprise market.
Milestones
2016
Origin PMF
Feishu started under the internal code name Lark, initially as a collaboration tool for ByteDance employees, focusing on document, schedule, and meeting management. At this stage, it was not commercialized externally at all. The team belonged to ByteDance's efficiency engineering department, with the core mission of running through collaboration efficiency and knowledge retention for tens of thousands of internal employees, validating high-frequency demand using real business scenarios.
2019
Commercialization Turning Point
In 2019, Feishu began opening up to external enterprise clients, launching two brands: Feishu for the Chinese market and Lark for overseas markets. ByteDance adopted a dual-arrow To B strategy, attempting to replicate the market entry path of Slack and Microsoft Teams in enterprise collaboration. However, Feishu's early customer acquisition was not smooth, and its expansion into government and enterprise markets was noticeably slower than DingTalk and WeChat Work.
2021
Independent Elevation Inflection Point
Feishu was elevated to one of ByteDance's six major independent business units, standing at the same tier as Douyin and TikTok. On the surface, this organizational upgrade showed strategic importance, but in reality, it also brought greater revenue pressure to Feishu. According to subsequent reports, Feishu was still in a continuous investment period at that time, with a significant gap in commercial scale and ecosystem volume compared to DingTalk and WeChat Work, and breakthroughs with large government and enterprise clients were slow.
2025
Growth Growth
Feishu's annualized revenue once reached approximately 3 billion RMB, with clients covering advanced manufacturing, new energy, retail chains, and new consumption industries. The team size also expanded to several thousand people, but it remained distant from the explosive growth expected within ByteDance. Meanwhile, the Doubao large model rapidly rose as ByteDance's new strategic focus, and Feishu's resource priority within the group began to be diluted.
2026
Split Turning Point
ByteDance issued an internal email merging the Feishu product team with the Doubao product team to form a new Doubao product team, while the Feishu GTM team was merged with the Volcano Engine team to establish a new To B organization named the Creativity Service Platform. This meant that the Feishu brand, which had operated for a decade, no longer existed as an independent business unit; its enterprise collaboration scenarios and permission systems were injected into Doubao, and its commercialization capabilities were merged into Volcano Engine.
Turning Points
- Feishu started as an internal ByteDance tool code-named Lark, completing product refinement through high-frequency scenarios serving tens of thousands of its own employees.
- When external commercialization launched in 2019, it rolled out the Feishu and Lark brands simultaneously, but government and enterprise market expansion lagged significantly behind DingTalk and WeChat Work.
- In November 2021, Feishu was elevated to one of ByteDance's six major independent business units, and its strategic status reached its peak.
- On July 30, 2026, the Feishu product team was merged into Doubao and the GTM team into Volcano Engine, officially ending its independent business identity.
Failures & Pitfalls
- Feishu's expansion into government and enterprise markets fell short of expectations, and its ecosystem volume consistently failed to catch up with DingTalk and WeChat Work.
- After being elevated to an independent business unit, Feishu still struggled to shake off its internal tool DNA, resulting in low sales conversion efficiency toward large external clients.
- Having operated as an independent brand for a decade, Feishu was ultimately split due to the group's All in AI strategy, with its SaaS path giving way to the scramble for large model entry points.
关键成功要素
- First served tens of thousands of internal ByteDance employees, validating the PMF of collaboration tools using real business scenarios.
- Simultaneously launched the dual brands Feishu and Lark, targeting domestic and overseas enterprise service markets respectively.
- Upgraded in 2021 to one of six major independent business units, matching the level of Douyin and TikTok, reaching peak strategic status.
- Forced to split under the AI wave in 2026, with product capabilities merged into Doubao and commercial capabilities into Volcano Engine.
Lessons
- Transitioning an internal tool to an external SaaS cannot rely solely on product refinement; government/enterprise sales and ecosystem building are the decisive factors for commercial success.
- A tech giant's strategic focus can shift rapidly with the founder's will, and the identity of an independent business unit does not guarantee long-term resource security.
- When AI large models become a group-level strategy, mature SaaS products may also be downgraded to entry-level components or ecosystem supplements.
- The moat of collaboration tools lies not in the number of features, but in user relationship chains and the depth of ecosystem integration.

Competitors / Peers
Feishu's main rivals in the domestic enterprise collaboration market are DingTalk and WeChat Work. DingTalk relies on Alibaba Cloud and the SME ecosystem, while WeChat Work cuts in via WeChat's social relationship chain. Both have long led Feishu in government/enterprise coverage and ecosystem scale. In overseas markets, Lark benchmarks against Slack, Microsoft Teams, and Notion, but has failed to achieve a clear breakthrough in either brand awareness or the number of paying enterprise customers. In the 2026 AI office race, new players like WorkBuddy and Qwen have also begun entering the desktop war, further squeezing Feishu's existing space.
