San Francisco startup Mount Thor has raised $45 million in seed and Series A equity funding to expand cloud infrastructure that gives AI developers on-demand access to Apple’s macOS operating system and silicon.
According to the company, CRV and Conviction co-led the Series A, while Chad Byers and Offline Ventures co-led the seed round. Other investors included CSC Leasing, Enea Capital, Long Journey Ventures and Upper90, along with individuals associated with Cognition, Core Automation, Daytona, Meta, OpenAI, Together AI and Vercel. The company also secured an undisclosed amount of non-dilutive capital to purchase hardware.
Founded in 2026, Mount Thor develops and operates data center systems built around Apple hardware, providing computing resources for AI research, software development and running AI models.
The financing will support additional computing capacity and hiring, particularly as the company develops infrastructure for running open-source AI models on Apple silicon.
Building Infrastructure for AI Agents
Mount Thor is focused on developers of AI agents that use computers to perform tasks, including those requiring software available only on macOS, by building and managing rack-scale systems of Apple hardware to allow customers to access computing environments remotely rather than maintain their own equipment.
“Making Apple’s operating system and silicon available at datacenter-scale is a massive untapped opportunity in AI infrastructure,” said Peter Voell, Founder and CEO of Mount Thor. “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. And with chips like the M5 Ultra, Apple silicon is becoming a high performance, more power- and cost- efficient platform for production inference.”
Mount Thor identified several uses for the infrastructure:
- AI research: Creating reinforcement learning environments for computer-use models.
- Agent testing: Providing secure macOS environments for developing and evaluating AI agents.
- Long-running operations: Supporting agents that operate for weeks across a user’s devices using the same Apple identity.
- Software development: Building, testing and simulating applications for Apple devices.
- AI inference: Running open-source models optimized for Apple silicon.
Mount Thor reported deploying its first data center in less than six months and plans to increase capacity as demand grows. Its team includes people who previously developed infrastructure at Cerebras, CoreWeave, Fluidstack, Nebius, OpenAI and xAI.
