About us
We teach AI to use phones, so your team doesn't have to tap through every release
OneGreen is a Hanoi-based startup building Green Phone Agent — AI agents that operate real phones to test mobile apps.
Our story
OneGreen started by building and operating cloud phone infrastructure: fleets of real devices that customers could control remotely. Running phones at scale taught us how differently apps behave on real hardware and real networks.
When AI models learned to understand screens and take actions, we saw the missing piece. Combine an agent that can see and reason with a lab of real, owned phones, and mobile testing no longer needs armies of manual testers or fragile scripts.
Green Phone Agent is that combination. We're building it together with early-access teams who ship mobile apps where quality really matters.
Mission
Make shipping a high-quality mobile app as simple as describing how it should work.
What we believe
Evidence over assumptions
Every verdict should come with proof anyone can check.
Real over simulated
Users run apps on real phones, so tests should too.
Trust by design
Owned devices and clean sessions — no shortcuts.
Humans in charge
Agents remove repetitive work; people decide what quality means.
