BlackBerry Limited
Balsillie was hired by Mike Lazaridis in 1992, when Research In Motion (RIM), an early venture into handheld telephony technology, had 14 employees. RIM would eventually become the "international powerhouse" called BlackBerry Limited, and have as many as 18,000 employees. Both men prospered from this companionship, with Lazaridis looking after the technological side while Balsillie looked after the sales business and accounting end of things.
