Ahmad Malkawi
Ahmad Malkawi
CEO and Founder

Ahmad Malkawi has worked for +20 years in the mobile/wireless industry for tier1 companies including AT&T, T-Mobile and Qualcomm. He founded Global Telecom to address a major gap in the development of modules – the “brains” at the heart of every smart device (from your iPhone to your Roomba and your Nest to your car). Global Telecom is the only U.S. manufacturer of these devices at a time when China has rapidly taken nearly two-thirds market share in recent years. His emphasis on homegrown technology with elite security (a special form of blockchain that keeps foreign entities out of your computer systems) has proven to be very prescient. These “driverless” and “host-less” modules just earned him a second U.S. patent, which was awarded in May 2020. And with 5G finally becoming a reality across the globe, analysts predict the number of modules in our homes and offices to jump by at least 10 fold in the next five years. Ahmad has positioned this company to takeoff with big name partners and proprietary technology that’s second to none.

Most recently, Ahmad led Global Telecom with awards including Association Corporate Growth (ACG), IOT Evolution Product of the year, Hottest New IOT Device and many other awards.
