About Mobilebox
Mobilebox makes mobile sandboxes for AI agents: cloud Android phones, iPhone and iPad, and real Android devices that your agent sees and controls over a REST API and a hosted MCP server. Mustafa Yenler, founder of fifteenA, builds it in Berlin and San Francisco.
Why a phone for agents.
Agents already have code and browser sandboxes. Much of what people do happens in phone apps.
Coding agents build Android and iPhone apps, then can’t open them: cloud agent sandboxes have no hardware acceleration, and a local emulator needs a screen and a fast machine. Other agents need an app that has no website at all. Mobilebox gives each of them a phone over one API: the agent reads the screen as numbered elements, taps and types by number, installs apps, and parks the phone to keep its logins for the next run.
Your agent and its model do the reasoning, on the provider you already use. We run the phones and bill phone-minutes. See what a mobile sandbox is and pricing.
