Clumio Inc., a provider of backup and recovery software for cloud environments, today announced that it has closed a $75 million funding round led by Sutter Hill Ventures.

Index Ventures, Altimeter and NewView Capital chipped in as well. The Series D raise follows a year in which Clumio claims to have quadrupled its ARR, or annual recurring revenue. The company says its ARR is now “well into double figures in millions of dollars.”

Clumio provides a platform that enables enterprises to create backups of the information they keep in Amazon Web Services and quickly restore them if the main copy becomes unavailable. The platform can protect relational databases, unstructured information repositories and a range of other AWS workloads. It also works with Microsoft 365, the Microsoft Corp. product bundle that includes the Office productivity suite.

“Customers have reached a point of maturity in the public cloud where backup and recovery of their critical data is now a top priority,” said Clumio co-founder and Chief Executive Officer Poojan Kumar (pictured). “It is foundational to their operational resilience, ransomware recovery, and regulatory compliance needs.”

Many ransomware strands encrypt not only companies’ business information but also their backups, which makes restoring the data impossible. Clumio’s platform stores backups in an immutable format that can’t be deleted or modified. The technology ensures customers don’t lose the ability to restore files after a ransomware attack, which limits the risk posed by such incidents.

The extent to which immutable backups mitigate the impact of a breach depends on how they’re used. If a company backs up its files every hour, it will at most lose an hour’s worth of information in the event of a ransomware attack. But if the most recent immutable copy of those files is from two weeks ago, a breach could cause a major business disruption. 

Clumio’s platform can analyze customers’ backup practices to determine if they’re prepared for a ransomware attack. The software evaluates the frequency of backups, data retention policies and other technical factors. Based on this information, it generates a so-called ransomware recovery score as well as a set of improvement suggestions when necessary.

Another selling point of the platform is that it promises to help companies lower their storage costs. Clumio has built algorithms that can automatically find unnecessary file copies, snapshots and other redundant data assets. It says deleting those files allows customers to cut their backup costs by up to 30%.

The company disclosed that its platform protects more than 100 petabytes of data for hundreds of organizations. Those customers include Atlassian Corp., Siemens AG and other publicly traded companies. To grow its market presence, it will invest the proceeds from the funding round in product development and go-to-market initiatives. 

“Clumio is seeing a deluge of demand across cloud databases, data lakes and high-performance storage,” Kumar detailed. “We will use our Series D funding to accelerate our momentum in these areas, across the major cloud providers.”
