Jake Leach, now CEO of glucose monitoring company Dexcom, began his professional career in the 1990s as a lab washer at medical technology company MiniMed. He earned ten dollars per hour for the job. Today he leads a company valued at around 30 billion dollars. Leach attributes his rise to hard work and a willingness to take on inconspicuous tasks.
Leach grew up in the San Fernando Valley in California, where the family budget was tight. He first attended a community college and then transferred to the University of California, Los Angeles (UCLA). There he earned a degree in electrical engineering and biomedical engineering. He was the first in his family to earn a four-year university degree. The path from the dishwashing area of a laboratory to studying at one of the country's best-known universities marks the starting point of a career that he today describes as the result of perseverance.
After graduating, Leach initially stayed at MiniMed, which was acquired by the Medtronic group in 2001. He remained at Medtronic for about seven years. In 2004 he moved to Dexcom, a start-up with about 30 employees. With the move, his salary reportedly rose from 45,000 to 95,000 dollars, more than double. Dexcom went public in 2005 and has since grown into one of the better-known names in continuous glucose monitoring.
Within the company, Leach worked his way up step by step. In 2018 he became Chief Technology Officer, and in 2022 Chief Operating Officer. In January he was finally appointed President and Chief Executive Officer. The report does not specify the year of this appointment. By his own account, he never applied for a promotion during his 22 years at Dexcom. He describes his development as a result of personal initiative: those who take on tasks others refuse get to know the company on several levels.
According to company information, Dexcom today reports annual revenue of around 4.6 billion dollars in 2025. Around 3.5 million people worldwide use the company's systems, and it employs about 11,000 full-time staff. According to the report, part of the growth is linked to GLP-1 medications, which have drawn greater attention to glucose measurement. Leach's base salary is given as 1.15 million dollars per year. The figures come from the company's presentation in the Fortune profile and were not independently verified by this editorial team.
Leach advises young employees to look beyond their own functional area, which he describes as their own lane, and to volunteer for tasks others avoid. Those who get involved gain insight into the company as a whole and access to opportunities that would otherwise remain hidden. His career shows how, over more than two decades, a simple job in the laboratory can lead to a leadership position at one of the larger medical technology companies in the industry, without the path running through formal promotion applications.
