About
was founded in 1989 by Joe Kiani, a 25 year old entrepreneur from Iran, to develop a revolutionary improvement to pulse oximetry systems. At the time, the pulse oximetry market was dominated by a single competitor, Nellcor. Joe and his team worked for nearly six years to perfect their new technology - Masimo SET - and introduced it to the market in 1996. Despite extraordinary resistance by Nellcor, which included patent infringement and anticompetitive activity, Masimo's superior technology ultimately became the standard of care in pulse oximetry. Masimo has since introduced many additional revolutionary technologies, including the first non-invasive measurement of hemoglobin. Masimo has annual sales of approximately $400 million and a public market cap of $2 billion.
