Past deals in Storage Services

Hammerspace

Series B in 2025
Hammerspace is a software-defined data orchestration and storage company that provides a unified, cross-platform file access solution through a Parallel Global File System. This system spans diverse storage types, vendors, locations, and clouds, creating a global namespace that enables direct multi-protocol access to all files regardless of storage or geography. A common metadata layer is shared across users and locations, so files are accessed via a single metadata view rather than duplicated copies. When local processing is needed, instantiation of a file is orchestrated in the background and remains transparent to users. The platform virtualizes and abstracts data from underlying infrastructure, delivering file data as a service to applications and data services, supporting hybrid IT environments with minimal disruption to workloads.
