Two fintech powerhouses that went public this year, Robinhood Markets and Coinbase Global, both hired new employees at among the fastest clips in the tech industry in their most recent quarters, according to an analysis by The Information of publicly traded tech companies.

Each of the two companies saw their headcounts jump at triple-digit rates for the quarter ended June 30 compared to a year earlier, as the chart above shows. The big increases mirror the breakneck pace of revenue growth at both companies, which has forced them to beef up their customer service and compliance teams as they step under the more intense spotlight aimed at publicly traded companies. At the same time, Twilio, Okta, Zoom Video Communications, Amazon and CrowdStrike—each of which hired at among the fastest rates in the tech industry over the first year of the pandemic—continued in that vein in their recent quarters.
