About Joe Kiani

Joe Kiani founded and runs medical technology firm Masimo Corp., whose devices non-invasively measure oxygen levels in patients' blood.

Kiani, an immigrant from Iran who studied electrical engineering in the U.S., came up with a way to vastly improve the performance of pulse oximeters.

Following years of struggle to break into the U.S. hospital market, Masimo became the leader in pulse oximetry for hospitals.

In February 2022, Kiani led Masimo to purchase Sound United, owner of speaker and headphone brands Marantz, Denon, Bowers & Wilkins and more, for about $1 billion.

In October 2023, the U.S. International Trade Commission ruled that some of Apple's watches infringed on Masimo's patents for pulse oximeters; Apple has appealed the decision.
