Bring technology into real scenarios
We are a lean team of 7 spanning hardware, embedded systems, cloud platforms and industrial design. Short decision chains mean your idea can be on site next week.
Why JoHan
Real scenarios, not demos
Your code is used daily by frontline staff at State Grid, PetroChina and Saudi Aramco — the feedback is direct and real.
Short decision chains
In a team of 7, idea-to-site validation is measured in weeks, not layers of approvals.
Industry-academia depth
Backed by the SJTU Technology Transfer Center, with access to frontier research and a China–Australia network.
Zero to one
Both in-house product lines — VPP and smart wearables — are early stage, with real room to grow for core members.
