Mount Thor has raised $45 million across seed and Series A rounds to build data centers that rent out Apple silicon by the hour, the company said on November 12, 2026. CRV and Conviction led the Series A, while Chad Byers and Offline Ventures led the earlier seed round. The company has not disclosed a valuation.
What Mount Thor builds
Mount Thor operates bare-metal Mac servers and isolated macOS virtual machines that customers rent the way they would rent a cloud instance. Its hardware runs on Apple's M5 Ultra Mac Studio, configurable with up to 512 gigabytes of unified memory, and is marketed for training AI agents that operate computer interfaces, running secure sandboxes, and powering build-and-test farms for Apple software.
Founded in 2026, Mount Thor deployed its first data center within six months of starting the company. Its team was recruited from Cerebras, CoreWeave, Fluidstack, Nebius, OpenAI, and xAI — companies that build general AI infrastructure rather than Apple-specific tooling, a hint at how Mount Thor frames its own market. "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.
How the money will be used
Mount Thor plans to spend the $45 million expanding its compute footprint and hiring, after what it describes as strong early customer demand. The company has also arranged separate, non-dilutive financing to buy additional Mac hardware, keeping equipment purchases off its equity balance sheet as it scales.
Investors and prior rounds
Beyond its lead investors, Mount Thor's rounds drew participation from CSC Leasing, Enea Capital, Long Journey Ventures, and Upper90, along with angel investors from OpenAI, Meta, Cognition, Together AI, and Vercel. The company has not broken out how much of the $45 million came from the seed round versus the Series A, nor has it disclosed a valuation for either round.
Competitors and market context
Mac-based cloud infrastructure is a narrow niche compared with general-purpose GPU clouds, but it has existing players. MacStadium has rented Mac hardware to software developers for over a decade, and Amazon Web Services added Mac instances to EC2 in 2020, primarily for iOS and macOS build pipelines. Mount Thor's bet is that demand for Apple hardware is shifting beyond app development toward AI agents that need to operate inside a real macOS environment to be trained and tested — a workload none of the established Mac-hosting providers were originally built around.
What to watch next
The open question is whether training AI agents on macOS turns into a durable, large-scale compute category, or stays a smaller add-on to the GPU-dominated AI infrastructure market. Mount Thor's next moves — how fast it adds data centers beyond its first deployment, and whether it signs large enterprise customers rather than developer-scale users — will indicate which outcome is more likely. The raise was first reported by 9to5Mac.
