Atoms · agentic hardware
One job each, done well. CallBox is the first atom.
CallBox
A small box with your own SIM. Your software or an AI agent makes and answers real calls and texts, at a flat cost instead of per minute.
Status: working prototype. Real calls and SMS on a SIM today; founder batch open for early access.

How it works
CallBox takes an ordinary SIM from the mobile carrier you already use. The calls go out on that line and its plan.
Your code or an AI agent tells the box to call, answer or text, and gets the conversation back.
The call happens on the box, on a real mobile network. No cloud phone service sits in the middle.
Cost
No prices yet: CallBox is a working prototype.
Usually billed per minute and per message, plus a monthly fee for each phone number. The bill grows with every call.
You pay for the box once, and your SIM plan covers the calls and texts. The cost stays the same however many calls the software makes, within that plan.
