Nutanix is a cloud computing software company that sells what it calls hyper-converged infrastructure (HCI) appliances and software-defined storage.

Nutanix was founded in 2009 by Dheeraj Pandey, Mohit Aron and Ajeet Singh. In early 2013 Aron left Nutanix to start Cohesity, a privately held enterprise storage company.

Venture capital firms invested $312.2 million over five rounds of funding. Nutanix reached a $1 billion valuation by 2013, which made it known as a "unicorn startup". It raised $140 million in a Series E round of financing in 2014, valuing the company at approximately $2 billion.

Nutanix filed for an initial public offering (IPO) in December 2015, reporting a net loss in its fiscal year ending July 2015 of $126 million. It reported about 1800 employees as of April 2016. Updated registration statements were published several more times, including one on August 16, 2016, showing growing losses as well as revenue, along with positive cash flow from operations. Later in August 2016, Nutanix announced it had acquired PernixData.

The IPO on September 30, 2016, raised about $230 million. Analysts expected Nutanix's public offering would be delayed.
