Mount Thor raises $45 million to rent Apple Macs in the cloud to AI agent developers

Mount Thor, a San Francisco startup founded in 2026, has raised $45 million across seed and Series A rounds to expand cloud infrastructure built on Apple hardware, The AI Insider reported. The report does not name the investors.

The company builds and runs rack-scale systems of Apple computers and rents remote access to macOS and Apple silicon to AI developers. Its main customers are builders of computer-use agents, AI systems that operate software the way a person would, including programs that only run on macOS. It also lists reinforcement learning environments for training such models, secure macOS sandboxes for testing agents, long-running agents that work across a user's devices, app development for Apple platforms and running open-source models on Apple chips.

"Making Apple's operating system and silicon available at datacenter-scale is a massive untapped opportunity in AI infrastructure," said founder and CEO Peter Voell. Mount Thor says it deployed its first data center in under six months and that its team includes people who built infrastructure at Cerebras, CoreWeave, Nebius, OpenAI and xAI.
