Nasuni Corporation is a privately held hybrid cloud storage company[5] with headquarters in Boston, Massachusetts.[6]

Nasuni is an unstructured data platform for enterprises where file data is necessary for both people and AI[7]. Nasuni supports the files that users work on — helping organizations to manage, protect, and activate data so that teams of users can work smarter, reduce costs, and operate securely.

Nasuni technology is built on a patented architecture that combines cloud object storage with enterprise file services — including permissions, versioning, and a global namespace. Nasuni delivers high-performance file access, global data availability, and a scalable, governed, AI-ready single source of authoritative file versions across every major cloud provider.

Nasuni helps more than 1,300 organizations to modernize file infrastructure, strengthen data security, and support AI-driven operations.

History

Nasuni was founded in 2009, and has raised approximately $169M, with the last funding a $25M investment in which all previous investors participated, including Goldman Sachs, Telstra Ventures, and Northbridge Venture Partners.[8]

In the time since Nasuni requested a patent on UniFS in November 2013, the company has expanded its access to cloud storage infrastructure, as well as its on-premises edge appliance offerings, which provide local access to content stored in Nasuni-managed cloud storage.[9]

On 14 July 2020, Nasuni Corp. collected $25 million in a new round of funding, plus an additional $15 million debt facility, and upgraded its cloud file storage platform to support remote workers.[10]

In May 2022, Nasuni acquired the technology assets of DBM Cloud Systems in order to provide enhanced data migration and cloud portability features.[11]

In June of 2022, Nasuni acquired Storage Made Easy, a file data management company, for an undisclosed sum. [12]

In July 2024, Nasuni announced a strategic growth investment led by Vista Equity Partners, a global investment firm focused exclusively on enterprise software, data, and technology-enabled businesses. Vista was joined by TCV and KKR in the new investment, which valued Nasuni at approximately $1.2 billion.[13]

In April 2025, Sam King became CEO. Former CEO Paul Flanagan continues as a member of the Board of Directors.

In March 2026, Nasuni acquired Resilio, Inc.[14] Resilio delivers high-performance data movement solutions built on a modern architecture that enables enterprises to move faster, unlocking competitive advantage through superior data accessibility at any scale. Resilio’s Active Everywhere Platform enables demanding data-intensive workflows for leading organizations in architecture and engineering, media and entertainment, and financial services.

Technology

The firm’s storage software uses object storage,[15] file caching appliances, and the company’s proprietary UniFS global file system[16] to offer a cloud solution that replaces traditional file servers and Network Attached Storage (NAS). Nasuni integrates with public cloud storage platforms, such as Google Cloud Storage,[17] Amazon Web Services, and Microsoft Azure,[18] and private cloud storage platforms such as IBM Cloud Object Storage and EMC Elastic Cloud Storage (ECS).[19] Such storage platforms provide an object-based storage infrastructure, on top of which UniFS creates a complete versioned file system.[20] The Nasuni platform stores customer data as a sequence of snapshots that include every version of every file. The firm has demonstrated the ability to store more than one billion objects in a single storage volume.[21]

Nasuni Edge Appliances run in the public cloud or on-premises to provide shared access to cached copies of active files. These Appliances are typically deployed as virtual machines, running on existing infrastructure, including VMware, Nutanix hyper-converged infrastructure, and Microsoft Hyper-V. The Edge Appliances can also run in the cloud on Microsoft Azure, Amazon EC2, or Google Cloud Platform. Hardware appliance choices offered by Nasuni include systems with solid-state drives.[22]

Nasuni’s File Data Platform provides a variety of services, including the following:

  • Multi-site collaboration that enables multiple users in multiple locations to work on the same files. [23]
  • Global file lock to ensure that only one user is changing a file at a time. [24]
  • Global file acceleration that optimizes the distribution of files to users. [25]
  • Access Anywhere to enable users to access the files they need from any location. [26]
  • Rapid recovery from ransomware attacks. [27]
  • Professional services to assist with migrating data to cloud storage. [28]
