Mount Thor raises $45 million to rent Apple Macs to AI agents

Mount Thor, a startup in San Francisco, raised $45 million in equity funding. It rents Mac computers in data centers for AI research, and it plans to operate open-source models on Apple chips. AI agents that use software can operate apps on macOS, the system software of those computers. The company also raised different funds for hardware, but does not say how much.

How it works

A customer can rent a full Mac computer. A customer can also rent a virtual machine, a software copy of a computer, on a Mac for that customer only. The virtual machine plan is in preview.

The numbers

The $45 million total is for Seed and Series A rounds. CRV and Conviction led the Series A. The company says it made its first data center in less than six months.

What is not known

The company does not say how it divides the $45 million between the rounds. The company gives no prices or test results for its plan to operate open-source models on Apple chips. Controls must fit each task, above all if an agent uses accounts or files of the customer.

Insight: Mac computers can become a toll gate for agents

In October 2026, Alibaba gave a sandbox for agent code to a neutral standards group. Mount Thor sells Mac computers that operate macOS. This reads as a toll gate: the owner of the Macs possibly collects rent from agents that must use macOS. Find out if open sandbox standards add macOS.
