Full text of Liang Rubo's latest speech: The peak of AI far surpasses that of PC, Web and mobile Internet, and ByteDance must bravely scale new heights.

On September 15, 2026, the 2026 Feishu Future Infinite Conference & Doubao Work Launch Conference was held in Beijing. Liang Rubo, CEO of ByteDance, attended the conference and delivered a speech, endorsing the first "integration" of Feishu and Doubao Work. This marks Liang Rubo's second public appearance focused on AI strategy this year following the Volcano Engine FORCE Conference in June, and is widely regarded by the public as a key tone-setting move of ByteDance in the enterprise service and productivity track.

In this speech, Liang Rubo sent a clear signal: ByteDance has integrated the strengths of Doubao, Feishu and Volcano Engine, focused on developing high-quality work and productivity products, and will invest more resources and efforts in the enterprise market.

He systematically expounded his core judgment on the cycle of the IT industry — over the past 50 years, there have been four industry peaks in the IT field: PC, Web, mobile Internet and AI, and the peak of this round of AI will far exceed the previous three. "Peaks do not appear often. Each of them was 15 to 20 years apart in the past. Such a rare opportunity requires us to strive to climb to the top."

He also reviewed the course of Feishu from its project initiation in 2016 to its official release in 2019, emphasizing that office collaboration will be recreated in every technological revolution. Feishu started its journey in the Mobile era, and hopes to seize its own opportunities in the AI era.

The full text of the speech is as follows:

Xin Xie just shared the development of Feishu over the past 10 years, and I was deeply touched as well.

When Feishu was first launched in 2016, I was actually in charge of the technical work back then. Let me first show you what Feishu looked like at the very beginning. The picture on the left is the design draft of Feishu in early 2017, 9 years ago. You can see that it only had the most basic message function, without even a calendar feature.

The one on the right is a message Xin Xie sent to me. The two exclamation marks indicate that the message failed to send. His avatar did not show up either. Comparing that with the current Feishu, I feel a lot of emotions.

This is a Moments post I made in April 2019, when we released the global version of Feishu. I wrote: This is the product I have spent the longest time polishing at ByteDance so far. For our ToC products, the cycle from project initiation to release is generally 3 months, but Feishu took 3 years.

We have always believed that the office collaboration system is critical to a company. After trying various solutions including free, paid, open-source and closed-source ones, we even found that the lack of a proper system restricted the development of the company, so we finally made up our mind to launch the Feishu project in 2016.

Over the past 10 years, Feishu has indeed greatly helped the collaboration among ByteDance colleagues, and we have also gained a lot, including all the happy customers present here. You have accompanied Feishu on a long journey, and helped Feishu get better and better. Thank you all entrepreneurs for your support and trust.

ByteDance sets an annual keyword every year to guide the work of the whole year. This year we set it as "Strive to Climb the Peak", and today I would like to give you a brief introduction to it.

We believe that over the past 50 years, there have been only four peaks in the IT field: PC, Web, Mobile and AI. Cloud is the infrastructure developed after the Mobile era. This picture was originally drawn with each peak a little higher than the previous one. I deliberately asked my colleagues to cut the height of the first three peaks by half, because I think by comparison, the AI peak will be much higher than all the previous ones.

What I emphasized to the team about this picture is, first, peaks do not appear often. As you can see, each peak was 15 to 20 years apart in the past, so the opportunity is extremely rare. We can also see that Google succeeded at the Web peak. However, even if a company has climbed one peak, it is very likely to fall off when a new peak arrives. I told the team this mainly to emphasize the sense of crisis.

Today, I want to look at these revolutions from the perspective of office collaboration. As a very fundamental demand, office collaboration has been a core application since the PC era, and it will be recreated in every technological revolution. This revolution is even more enormous, and will bring qualitative leaps.

Feishu can be regarded as having caught the train in the Mobile era, and we hope that Feishu can fully seize its own opportunities in the AI era.

At the same time, we can see that from Office to Office 365, and then to Teams, Office has developed very well in the past three technological revolutions, and its status is even more stable than Windows.

At the end of last year, the Agent capability of large models began to enter the usable stage, and the implementation of AI in productivity scenarios has accelerated significantly. Doubao Work is exactly a productivity Agent product. In addition, Agents do not exist in isolation, they need to collaborate with people, the environment and other Agents. Meanwhile, Agent capabilities are also closely related to the model. Therefore, Agents, models and collaboration environments need to be closely integrated. That is why we integrated the strengths of Doubao, Feishu and Volcano Engine two months ago, to focus more on developing high-quality work and productivity products.

From the perspective of customers, what you may care about first is that Doubao Work can provide intelligence, while Feishu, as a collaboration platform, carries the enterprise's context and tools. With the combination of the two, every employee can use AI naturally and efficiently in work scenarios, and create better value.

In addition, enterprises also have the demand to build their own exclusive Agents. At this time, Volcano Engine can provide models, computing power and development tools, to turn the unique experience of enterprises into their own Agents. These Agents can also access Feishu to collaborate with people and other Agents.

AI has a huge impact. All enterprises hope to develop with the help of AI instead of being impacted by it. This requires systematic transformation of the working mode, which is far more than what a set of tool systems can achieve.

ByteDance will invest more resources and efforts in the enterprise market, to enable intelligence to generate value in organizations faster.

This speech is sorted out from Liang Rubo's speech at the 2026 Feishu Future Infinite Conference on September 15, 2026, subject to the on-site and official release.
