Mount Thor, a San Francisco startup that rents out Macs running Apple silicon as cloud capacity, says it has raised $45 million across a seed round and a Series A. It announced the funding on 12 November 2026 and also reports separate non-dilutive financing for new hardware, with no amount given.
“Decades of investment in accessibility and human-computer interaction make macOS the best place for agents to work and for humans to hold them accountable.”

CRV and Conviction co-led the Series A, while Chad Byers and Offline Ventures co-led the seed. CSC Leasing, Enea Capital, Long Journey Ventures and Upper90 also took part, along with angel investors from OpenAI, Meta, Cognition, Together AI and Vercel. The valuation, the size of each round and revenue were not disclosed.
Founded in 2026, the company says its first data centre was running in under six months. Its team previously built infrastructure at Cerebras, CoreWeave, Fluidstack, Nebius, OpenAI and xAI. The pitch is that AI agents work well on Apple silicon and nobody yet rents Macs at data-centre scale. AWS has offered Mac instances for a few years and MacStadium for longer, but Mount Thor argues the bigger customer is now an agent that needs a Mac.

It sells two models. Managed compute is a full bare-metal Mac or an isolated macOS virtual machine with admin access, reached through a web portal, command line, Kubernetes or API and billed per Mac in 24-hour blocks. In customer-managed mode, an organisation runs its own Macs at a Mount Thor site under its own device management, while Mount Thor runs the facility, tracks inventory by serial number and reports problems. Uses it lists include training computer-use models in reinforcement-learning environments, secure sandboxes for agents and build-and-test farms for Apple software.
About Mount Thor
Mount Thor is a San Francisco cloud-infrastructure company, founded in 2026, that makes macOS and Apple silicon available on demand for computer-use research, agent deployment, software testing and enterprise inference. Built In lists it as a provider of managed Apple silicon infrastructure for frontier AI workloads, with dedicated, non-virtualised macOS machines at data-centre scale.
Before this funding it had already been named in an Implicator piece of 31 August 2026 about OpenAI buying Macs, which described Mount Thor, along with webAI, as an outside partner selling managed Mac environments for AI work that Apple relies on.
Founder and CEO Peter Voell says demand for macOS will grow with the number of agents rather than the number of people, and the company describes Apple silicon as an increasingly fast, power-efficient and cost-efficient platform for production inference. CRV general partner Brittany Walker frames the deal as two shifts converging: autonomous agents and rising demand for compute. The money is earmarked for more capacity and hiring, with an inference lab for open-source models on Apple silicon a stated focus. These are the company's and its investors' own claims.
