I wanted to be a doctor, but my grades weren't that good and chemistry was not my thing. Physics fortunately was. So I switched to engineering.

About Me

Joe Kiani founded medical technology firm Masimo Corp., whose devices non-invasively measure oxygen levels in patients' blood in 1989. Kiani was ousted from Masimo's board and resigned as CEO in September 2024 after activist shareholders won a proxy fight. An immigrant from Iran who studied electrical engineering in the U.S., Kiani came up with a way to vastly improve the performance of pulse oximeters early in his career. Following years of struggle to break into the U.S. hospital market, Masimo became the leader in pulse oximetry for hospitals. Kiani now serves as executive chairman of Willow Labs, which is rolling out techn to nudge people to improve their metabolic health, and as chairman of Like Minded Labs, which launched a virtual collaboration platform. Danaher agreed to buy Masimo for nearly $10 billion in February 2026.
