Dexcom president and CEO Jake Leach began in diabetes technology washing laboratory equipment for $10 an hour at MiniMed while saving for community college in California. He later studied electrical and biomedical engineering at Glendale Community College and UCLA, becoming the first person in his family to earn a four-year college degree. After seven years at MiniMed, which Medtronic acquired in 2001, Leach joined 30-person startup Dexcom in 2004, accepting an offer that increased his salary from $45,000 to $95,000. Dexcom went public in 2005 and by 2025 reported $4.6 billion in annual revenue, approximately 3.5 million users worldwide and around 11,000 full-time employees. Leach became chief technology officer in 2018, chief operating officer in 2022 and president and CEO in January. He says his advancement came from consistently solving major problems, developing leaders, learning from colleagues and taking on work beyond his formal responsibilities rather than seeking promotions.
