Feishu integrates Doubao; AI office billing shifts from trial-and-error to transaction-based models

Last Wednesday at noon, while I was revising peer review comments for a paper in the lab, my phone popped up a notification: Feishu team merged into Doubao. I stared at the screen for a few seconds, remembering how last year a student asked me during a group meeting, "Professor, what exactly does Feishu make money from?" I said that in principle, SaaS pricing models fall into two categories—either selling features or monetizing data. Feishu has always gone for the former, but that path is getting narrower and narrower.
