Rubrik, Inc. is a Palo Alto-based cloud data management and security company founded in January 2014 by Bipul Sinha, Arvind Jain, Soham Mazumdar, and Arvind Nithrakashyap. The company went public on the New York Stock Exchange on April 25, 2024, under the ticker RBRK, pricing its IPO at $32 per share to raise $752 million at a $5.6 billion valuation, with shares surging 16% on the first day of trading. Specializing in "Zero Trust Data Security," Rubrik provides backup and recovery for hybrid cloud environments, a market that has expanded significantly due to rising ransomware threats. It has grown through key acquisitions, including Datos.io (2018), Igneous (2020), and Laminar Security for $200 million (2023). Notable figures include CEO Bipul Sinha, board member John W. Thompson, and investor Kevin Durant, though the company faced a 2018 lawsuit from Dell EMC alleging trade secret theft by former employees.
