About us
A Hong Kong AI technology company built around product and engineering.
85 AI Technology Limited was founded in Hong Kong to put artificial intelligence to work in everyday operations and business processes. We build our own shared technical modules and run several products on the same foundation, covering contact management, elderly and family services, content creation and personal knowledge tools.
Our team owns product design, system architecture, development and operations, which keeps quality and pace consistent from requirements to launch.

Why us
Why work with us
We apply the same standard to every product: maintainable, verifiable, and able to grow feature by feature.
One team from product to launch
No coordination across multiple vendors; requirements, design, development and operations are handled by the same team.
AI that is actually in use
We apply models to real workflows - document recognition, data clean-up, customer replies and content generation - not just demonstrations.
Systems built to be maintained
Built on shared modules and automated checks, so features can be added one at a time instead of rewriting the product.
