History of Masimo

  • Founded: 1989
  • Founders: Joe Kiani
  • Acquired by Danaher Corporation: 2026

Joe Kiani founded Masimo in Irvine in 1989 with a technical conviction: existing pulse oximeters produced unreliable readings when patients moved or had poor circulation, precisely the conditions where accurate oxygen measurement mattered most. Masimo's Signal Extraction Technology (SET), introduced in 1995, solved that problem and established the company as the premium standard for pulse oximetry, eventually used in the majority of top-rated US hospitals.

Through the 2000s and 2010s, Masimo expanded from sensors into full patient monitoring: the rainbow platform measured additional parameters beyond oxygen, including hemoglobin and carbon monoxide; wearable devices like the Masimo W1 watch and Radius T continuous monitors extended monitoring outside the hospital; and the Root patient monitoring hub created an open platform for third-party parameters.

The 2010s brought a defining legal victory. Masimo's long patent fight with Apple over watch-based health sensing produced a 2023 ITC import ban on Apple Watch models with blood oxygen features, a rare case of a mid-cap medical company forcing action from the world's largest technology company. Apple disabled the feature on US models rather than remove them from sale.

The later years were turbulent. A 2022 acquisition of Sound United added consumer audio brands including Bowers & Wilkins and Denon, a diversification that investors questioned. Activist Politan Capital launched a proxy fight in 2023 over strategy and governance; Kiani lost board control in 2024 and resigned as CEO in September 2024, replaced by Katie Szyman. The company agreed to sell Sound United to Harman in 2025 and announced the Danaher acquisition in February 2026, completing it June 10, 2026 at $180 per share.

Masimo Recalls & Controversies

Apple Patent Litigation: Masimo's multi-year legal battle against Apple over pulse oximetry patents in the Apple Watch produced a 2023 ITC import ban on certain Apple Watch models and subsequent rulings awarding Masimo damages, while litigation continues over patent and trade secret claims.

Founder Proxy Fight (2023-2024): Activist investor Politan Capital won board control in a contested proxy fight that exposed governance disputes and led to founder Joe Kiani's September 2024 resignation as CEO after 35 years.

Sound United Diversification: The 2022 acquisition of consumer audio brands drew investor criticism for straying from the medical core, contributing to the activist campaign; the business was sold to Harman International in 2025.
