Thorsten Heins, a former Siemens AG executive who has risen steadily through RIM's upper management ranks since joining the Canadian company in late 2007, took over as CEO on Saturday, RIM said on Sunday.
The shift ends the two-decade long partnership of Lazaridis and Balsillie atop a once-pioneering technology company that now struggles against Apple and Google.
With RIM's share price plummeting to eight-year lows, a flurry of speculation that RIM was up for sale has enveloped the company in recent months. But investors have pointed to the domineering presence of Lazaridis and Balsillie as one reason a sale would prove difficult.
Activist investors have clamored in recent months for a new, "transformational" leader who could revitalize RIM's product line and resuscitate its once cutting-edge image. It remains to be seen whether RIM has found such a leader in Heins, analysts said.
"It's the first positive thing that they have done in months," said Charter Equity analyst Ed Snyder, even as he expressed caution over the choice of Heins, a longtime lieutenant of Lazaridis and Balsillie. "My feeling is that it's a figure-head change."
Michael Urlocker, an analyst with GMP Securities, questioned whether Heins had the right background for the job that faces him. "I am not sure that an engineer as new CEO really gets to the central issues faced by RIM," he said.
Lazaridis and Balsillie also gave up their shared role as chairman of RIM's board. Barbara Stymiest, an independent board member who once headed the Toronto Stock Exchange, will take over in that capacity.
The pair, who together built Lazaridis' 1985 start-up into a global business with $20 billion in sales last year, have weathered a storm of criticism in recent years as Apple's iPhone and the army of devices powered by Google's innovative Android system eclipsed their email-focused BlackBerry.
"There comes a time in the growth of every successful company when the founders recognize the need to pass the baton to new leadership. Jim and I went to the board and told them that we thought that time was now," Lazaridis said in a hastily arranged interview at RIM's Waterloo headquarters, flanked by Balsillie and Heins and with Stymiest joining via telephone
