About
I’m Lei Junjun, a product manager who has moved from software services into hands-on AI application building.
One question has stayed at the center of my work for a long time: how can AI genuinely help brick-and-mortar businesses?
Not by stopping at a few lines of copy or a few generated images, but by becoming part of the full chain of store operations, private-domain growth, campaign conversion, and team training.
Drawing on years of experience serving physical stores and customer-acquisition teams, I’m building a product portfolio around AI-powered private-domain fission growth.
I believe the AI products that create real long-term value will not be the ones that merely demonstrate capability, but the ones that fit into industry scenarios, solve specific problems, and produce measurable outcomes.
