Nasuni

Lore & Background

Nasuni was founded in 2009 by Andres Rodriguez, whose original idea for the company name 'NASUNI' is shorthand for 'NAS UNIfied'. The company filed a patent for UniFS in November 2013 and has since expanded its cloud storage infrastructure access and on-premises edge appliance offerings. In July 2020, Nasuni collected $25 million in a new funding round plus an additional $15 million debt facility, and upgraded its cloud file storage platform to support remote workers.

In May 2022, Nasuni acquired the technology assets of DBM Cloud Systems to enhance data migration and cloud portability features. The following month, it acquired Storage Made Easy, a file data management company, for an undisclosed sum. In July 2024, Nasuni announced a strategic growth investment led by Vista Equity Partners, joined by TCV and KKR, valuing the company at approximately $1.2 billion. In April 2025, Sam King became CEO, with former CEO Paul Flanagan remaining on the Board of Directors. In March 2026, Nasuni acquired Resilio, Inc., whose Active Everywhere Platform enables high-performance data movement for demanding workflows in architecture, engineering, media, entertainment, and financial services.

The company's technology integrates with public cloud storage platforms such as Google Cloud Storage, Amazon Web Services, and Microsoft Azure, as well as private cloud platforms like IBM Cloud Object Storage and EMC Elastic Cloud Storage. Nasuni stores customer data as a sequence of snapshots that include every version of every file, and has demonstrated the ability to store more than one billion objects in a single storage volume. Its Edge Appliances run in the public cloud or on-premises, typically as virtual machines on VMware, Nutanix, or Microsoft Hyper-V, and can also run on Azure, Amazon EC2, or Google Cloud Platform.

Nasuni's significance lies in its approach to enterprise file storage by replacing traditional file servers and NAS with a cloud-native global file system. The company's UniFS file system creates a complete versioned file system on top of object-based storage infrastructure, storing every version of every file as snapshots. This architecture supports multi-site collaboration, global file locking, file acceleration, remote access, and rapid recovery from ransomware attacks. Nasuni's integration with major public and private cloud platforms allows organizations to leverage existing cloud investments while maintaining local access through Edge Appliances. The company's patent portfolio covers key technologies including versioned file systems with pruning, sharing, fast restore, global lock, and cloud-native global file system features such as multi-site support, constant-time rekeying, and reshapable caching. Through acquisitions of DBM Cloud Systems, Storage Made Easy, and Resilio, Nasuni has expanded its capabilities in data migration, file data management, and high-performance data movement. The company's valuation of approximately $1.2 billion in 2024 and continued investment from firms like Vista Equity Partners, TCV, and KKR reflect its position in the hybrid cloud storage market. Nasuni has received awards for customer service and technology, including being named Cloud Enabler of the Year by Storage Magazine in 2024.
