Rubrik, Inc.
A maker of data security software, Rubrik helps businesses back up their data and defend against ransomware through its Rubrik Security Cloud platform and its newer Rubrik Agent Cloud for managing AI agents. Four engineers founded the company in 2014 to replace clunky, outdated backup systems. Its name comes from "rubric," a set of rules or a guide—though a job applicant once famously mistook it for the Rubik's Cube.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -5.51M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
