Rubrik is younger than Cohesity and is growing much faster than Cohesity.

Judge as of 2019-05-16. There are two parts. Rubrik is younger: compare founding dates (Cohesity is usually dated 2013, Rubrik 2014). Growing much faster: compare revenue or bookings growth rates reported for about 2018–2019. True: Rubrik was founded later and credible reports show clearly higher growth (for example, a growth rate notably higher than Cohesity's). Mostly true: both parts hold, but the growth gap is modest rather than 'much' faster. Mixed: only one of the two parts holds. Mostly false: Rubrik was younger but grew at a similar or slower rate, or was not younger but grew only slightly faster. False: Rubrik was neither younger nor growing faster.

Cohesity was founded in June 2013 (E1) and Rubrik in January 2014 (E2), so the claim that Rubrik is younger holds. StorageNewsletter's February 2019 ranking of the fastest-growing storage companies of 2018 lists Rubrik first at 500% growth for 2017/2018 and Cohesity at 300% (E7, E8). That is consistent with Cohesity's own report of 300% revenue growth in FY2018 (E3/E5). Rubrik's figure is clearly higher, but it comes from a single compilation that does not say what was measured (revenue or bookings), so the evidence for "much faster" is limited and the verdict is mostly true rather than true.
