Nasuni Secures $60 Million Growth Equity Investment from Sixth Street to Extend Market Leadership in File Data Services

March 24, 2022

Company Continues Rapid Growth as the Market Contends with Massive Data Growth, Cloud Adoption and Ransomware Threats

BOSTON, March 24, 2022 – Nasuni Corporation, the leader in file data services, today announced a $60 million equity investment by new investor Sixth Street Growth, the growth investing platform of global investment firm Sixth Street, which will also be joining Nasuni’s board. The valuation reflects a significant increase over the company’s previous capital raise closed 18 months ago. This rapid expansion is in response to accelerated demand for its file data platform and as organizations quickly move workloads to cloud environments to realize the benefits for increased scale, superior economics and heightened security from ever intensifying cyber threats.

This is the fourth round of financing Nasuni has raised over the last five years, in which they have raised a total of $148 million. With this financing, Nasuni now has approximately $100 million in cash on its balance sheet. The new investment will be used to fuel continued growth and expansion of Nasuni’s File Data Services as the company invests in innovation, international expansion and potential strategic acquisitions.

“The unprecedented events of the past 24 months have accelerated the generational cloud transformation for businesses and the increasing value of data,” said Paul Flanagan, chief executive officer, Nasuni. “Cybersecurity threats such as ransomware are forcing businesses to think differently about their data infrastructure. Nasuni pioneered the cloud-based file data services category almost a decade ago and has led the way in defining the architecture, business model and user experience. This investment and our continued, rapid growth are validation of our vision.”

Enterprises are aggressively adopting cloud solutions to strengthen cyber resilience, support hybrid work models and get frictionless scale to meet business needs. Based on this demand, IDC forecasts cloud file services adoption will reach a five-year compound annual growth rate (CAGR) of 40% and be a $14 billion market by 2025.This growth rate for file data is higher than both the block and object storage markets.

“Nasuni offers its clients great products, with solutions that are highly effective at solving pressing needs for efficient cloud data storage and data protection,” said Michael McGinn, partner and co-head of Sixth Street Growth. “Nasuni is poised to accelerate its already impressive organic growth through international expansion and the development of new features and capabilities as it continues to be a leader in the file data services market.”

As data grows exponentially in parallel to the new cloud operating model, traditional data storage and data protection based on hardware is no longer scalable, secure or cost-effective. Instead, businesses need a new approach which can be deployed from anywhere, have unlimited scale, protect data across the enterprise and deliver it securely as a cloud service. Only solutions built natively in the cloud will be able to successfully deliver on all of this.

The funding comes as Nasuni reported record-breaking results from its fiscal year ending December 31, 2021. The company saw significant year-over-year (YoY) growth in annual recurring revenues (ARR), a continued surge in customer wins globally and a rapidly increasing number of customers paying Nasuni more than $1 million in annual contract value. Nasuni also saw exceptional traction across its partner ecosystem.
