Rubrik

Rubrik was originally incorporated in Delaware in December 2013 under the name ScaleData, Inc. and renamed Rubrik, Inc. in October 2014. It was founded by Bipul Sinha (a former Lightspeed Venture Partners investor), Arvind Nithrakashyap (a former Oracle and Rocket Fuel engineer, who became CTO), Arvind Jain (a former Google engineer, who later left to found the enterprise search company Glean), and Soham Mazumdar. The founders set out to modernize enterprise backup, which they viewed as a legacy, fragmented category ripe for disruption via a scale-out, API-first, cloud-native architecture. Rubrik shipped its first product in 2015 and grew quickly by selling into enterprise IT organizations frustrated with legacy backup vendors like Veritas, Commvault, and Dell EMC.

The company raised a rapid succession of large venture rounds: a Series A (~2014, led by Lightspeed Venture Partners), Series B (2015, first Greylock investment), Series C (~2016), a $180 million Series D in May 2017 at a $1.3 billion valuation led by Institutional Venture Partners (IVP), and a $261 million Series E in January 2019 at a $3.3 billion valuation led by Bain Capital Ventures with Lightspeed, Greylock, Khosla Ventures, and IVP participating. Total primary preferred-stock capital raised prior to IPO was approximately $715 million (per Rubrik's IPO prospectus capitalization table). Along the way Rubrik attracted high-profile individual backers, including NBA star Kevin Durant, who has cited Rubrik as his first technology investment.

As ransomware became an existential threat to enterprises in the late 2010s, Rubrik repositioned from 'cloud data management' to 'Zero Trust Data Security,' emphasizing immutable, air-gapped backups, anomaly/threat detection (Radar), and sensitive-data discovery (Sonar) on top of its core recovery platform, later unified under Rubrik Security Cloud (RSC). The company made several acquisitions to accelerate this shift: Datos.io (early 2018, NoSQL data protection), the assets/IP of Igneous (December 2020, a Seattle unstructured-data company), Laminar Technologies (August 2023, ~$105–250 million reported, an Israeli data security posture management/DSPM company), and, after going public, Predibase (July 2025, $109.1 million, an AI/LLM developer platform used to expand into agentic AI security).
