About Amulet
Summary
Amulet builds a high-performance filesystem for parallel AI agent workloads, giving training runs, evals, and autonomous agents fast read access to petabyte-scale cloud data. Workspaces mount as standard Linux filesystems in under 100 ms, fork without copying data, and persist across disposable compute. It replaces ad-hoc data staging and manual checkpoint management for data-intensive AI teams running agentic pipelines.
Go-to-market
Amulet targets agentic automated-research labs and cloud agent providers, reached through direct access requests via the product website.

High performance file system for agents
Amulet is a high-performance filesystem that gives agent workloads fast access to petabytes of data stored in the cloud. We provide isolated, writable workspaces that mount in under 100 ms and fork without copying data. Work persists across disposable compute, and every workspace can be snapshotted, reproduced, merged, or rolled back. We’re working with agentic automated-research labs, cloud agent providers, and other to bring this infrastructure to data-intensive AI teams.
