In a recent, wide-ranging interview on the “Acquired” podcast, former Microsoft CEO Steve Ballmer provided a candid and energetic look back at his 34-year tenure at the software giant. The episode, released in early June 2025, delved into pivotal moments in Microsoft’s history, from its foundational deals to its struggles and successes in the modern era of technology.
Ballmer, who led Microsoft as CEO from 2000 to 2014, addressed the company’s landmark deal with IBM for the disk operating system (DOS) that set Microsoft on its path to dominance. He offered his firsthand perspective on the evolution of the company’s enterprise business, a division he was instrumental in building from the ground up, which remains a cornerstone of Microsoft’s revenue today.
However, the famously boisterous businessman did not shy away from the company’s significant missteps. He openly discussed his candid reflections on Microsoft’s failure to capitalize on the mobile and search markets, acknowledging the strategic blunders that allowed competitors like Google and Apple to establish formidable leads.
A central theme of the interview was Ballmer’s candid admission of Microsoft’s strategic blunders in the mobile market. He stated plainly, “We were too confident,” identifying an over-reliance on the Windows brand and business model as the core of the problem.
According to Ballmer, the critical mistake was not necessarily sticking with the Windows brand itself, but rather trying to force a PC-centric operating system and its corresponding APIs into the nascent smartphone market where it didn’t naturally belong. He explained, “I don’t think we stuck with Windows too long. I think what we did is we tried to put Windows in places that it didn’t naturally go.”
This Windows-centric approach, which Ballmer described as a mindset born of both “paranoia and confidence,” led the company to believe that Windows was their “birthright” and a “permission to enter” any new market. This resulted in products like Windows Mobile and the ill-fated Kin phone, which were fundamentally unnatural user experiences. Instead of building a new mobile-first ecosystem from the ground up, as Apple and Google did, Microsoft tried to shoehorn its existing PC dominance into a completely new paradigm. This failure to adapt and recognize mobile as a distinct platform, rather than a mere extension of the PC, was one of the most expensive missed opportunities in tech history.
The conversation also touched upon Ballmer’s famously complex and dynamic relationship with co-founder Bill Gates. He spoke about their partnership, the period where they reportedly did not speak for a year, and the ultimate decision for him to step down as CEO.
Ballmer confirmed that there were significant strategic disagreements between them and the board, which ultimately led to a period of about a year where the two former partners did not speak.
The primary source of the friction was a fundamental disagreement over Microsoft’s future direction, specifically concerning the move into hardware. Ballmer had championed the acquisition of Nokia’s phone business as a necessary, albeit late, step to compete in the mobile space. Gates and other members of the board were reportedly hesitant about the massive hardware investment. This clash over the Nokia deal, a move Ballmer felt was essential for survival in the mobile-first world, strained their relationship to a breaking point.
Ballmer explained that this professional disagreement became deeply personal, contributing to his decision to step down. The tension was not just about a single business decision but about the evolving soul of the company and the struggle between its legacy software identity and the need to transform into a “devices and services” company. While the two have since reconciled, the interview painted a picture of a difficult and emotionally charged period for both of the men who had built Microsoft into a global powerhouse.
Looking beyond his time at Microsoft, Ballmer discussed his subsequent success as the owner of the Los Angeles Clippers basketball team and his remarkable track record as an investor. He famously held onto his Microsoft stock after his departure, a decision that has seen his net worth multiply significantly. The interview also touched on his current philanthropic endeavors with the Ballmer Group.
Listeners of the nearly three-hour episode were treated to Ballmer’s signature high-energy delivery as he recounted the stories behind his famous “developers, developers, developers” chant and offered his unvarnished opinions on the tech industry, both past and present. The interview serves as a significant historical document from one of the key figures who shaped the modern computing landscape.
