IBM Chairman and CEO Arvind Krishna informed employees that Lou Gerstner, who led the company as Chairman and CEO from 1993 to 2002, died on December 27.
Gerstner took over IBM at a time when the company’s future was uncertain. The technology industry was changing quickly, and there were internal debates about whether IBM should remain a single company. Krishna wrote, “His leadership during that period reshaped the company. Not by looking backward, but by focusing relentlessly on what our clients would need next.”
Krishna recalled an early moment in Gerstner’s tenure: “One of Lou’s earliest signals as CEO has become part of IBM lore. Early on, he stopped a long internal presentation and said, simply, ‘Let’s just talk.’ The message was clear: less inward focus, more real discussion, and much closer attention to customers. That mindset would define his tenure.”
According to Krishna, Gerstner believed that one of IBM’s main problems was an internal focus on processes rather than customer outcomes. “As he later put it, the company had lost sight of a basic truth of business: understanding the customer and delivering what the customer actually values,” Krishna stated.
This perspective led to changes within IBM. Meetings became more direct and decisions were made based on facts and client impact instead of tradition or hierarchy. Innovation was prioritized if it resulted in value for clients.
Gerstner made a significant decision to keep IBM together as one company rather than splitting it into separate businesses. Krishna explained that Gerstner understood clients wanted integrated solutions rather than fragmented technology offerings.
Krishna also noted that Gerstner saw cultural change as essential for lasting progress at IBM. He pushed for renewal of the company’s values to fit new challenges while maintaining honesty and willingness among employees to challenge themselves.
Reflecting on his own experiences with Gerstner in the mid-1990s, Krishna described him as intense and focused—able to balance short-term delivery with long-term innovation.
Even after stepping down as CEO, Gerstner remained engaged with IBM. “From my first days as CEO, he was generous with advice—but always careful in how he gave it,” Krishna wrote. “He would offer perspective, then say, ‘I’ve been gone a long time—I’m here if you need me.’ He listened closely to what others were saying about IBM and reflected it back candidly.”
Krishna concluded by expressing gratitude for having learned from Gerstner regularly.
