The Builder Who Keeps Building
Before she reinvented the data center, Diane Greene was selling crabs off a dock in Annapolis for $5 a dozen. That detail matters. Not because it is quaint, but because the instinct - see a gap, fill it, get paid, move on - never left her. It just scaled up. Considerably.
Today, Greene holds board seats at Stripe, SAP, Intuit, Wix, and A.P. Moller-Maersk. She is Chair Emerita of the MIT Corporation, the first woman ever elected to that role in the institution's 160-plus year history. She has co-founded three companies, each acquired by a larger one. The combined exit value runs well past $1 billion. None of this was planned. She will tell you that herself.
Greene grew up in Annapolis, Maryland, in a world of boats and water and wind. She studied mechanical engineering at the University of Vermont, then naval architecture at MIT. She spent her mid-twenties designing actual ships - ocean-going vessels, offshore oil structures - for the maritime industry. Then she discovered windsurfing, ran the engineering division for Windsurfing International in Hawaii, won the San Francisco Classic women's division three times, and at age 19, organized the first Windsurfing World Championship. A sport she didn't invent. She just decided to professionalize it.
The pivot to software came in 1988, after a master's degree in computer science at UC Berkeley. The pivot, it turned out, was actually a collision course with history.
"When you race a sailboat, the selection of your crew is just completely paramount. It's impossible to be an effective skipper if you don't have the right people working harmoniously in the right roles." - Diane Greene
The first company she built from scratch was VXtreme, a streaming video startup she co-founded in the mid-1990s as CEO. Streaming video. In 1996. When dial-up modem tones were still a sound most people heard daily. Microsoft bought VXtreme for roughly $75 million. The technology became the basis for what would eventually be Microsoft's media player. Greene moved on.
In 1998, she and her husband Mendel Rosenblum - who she met at Berkeley when he gave her a ride on his motorcycle - co-founded VMware with three colleagues: Scott Devine, Edward Wang, and Edouard Bugnion. The idea was to allow multiple operating systems to run simultaneously on the same physical machine through software-based virtualization. This sounds obvious now. It was not obvious then. Most people in the industry thought it was either impossible or pointless. Greene thought it was the future of computing.
She was right. VMware's x86 virtualization technology became the foundational infrastructure layer for what we now call cloud computing. Without it, the economics of data centers - and therefore the economics of Google, Amazon, and every other cloud provider - would have developed differently, probably more slowly, possibly not at all in their current form.
EMC acquired VMware in 2004 for $635 million. Greene stayed on as CEO. In 2007, she led VMware's public offering, which priced at a $19.1 billion valuation - the largest technology IPO that year. A year later, VMware's board fired her. The stated reasons varied depending on which account you read: strategic clashes with EMC over the company's independence, concerns about operational experience as the company scaled, a revenue guidance revision. She declined an offer to remain in a different role. She was not interested in a different role at the company she had built.
The motorcycle story: Mendel Rosenblum gave Diane Greene a ride on his motorcycle when they met at UC Berkeley in 1985. They got married. Then they co-founded VMware together. Then they built one of the most important software companies in the history of enterprise computing. Possibly the best ROI on a motorcycle ride in Silicon Valley history.
Being fired from the company you co-founded would end most people's appetite for entrepreneurship. For Greene, it lasted about four years. In 2012 she joined Google's board of directors. That same year, she started Bebop - a platform-as-a-service company designed to make it easier to build enterprise applications. In 2015, Google acquired Bebop for approximately $380 million and simultaneously named Greene CEO of Google Cloud.
Her personal take from the Bebop acquisition - roughly $150 million in Alphabet stock - went directly to a donor-advised charitable fund. The money never cleared her personal account.
At Google, she inherited something that was not quite a business yet. Google Cloud was a capable technical platform with a startup-focused customer base and two significant enterprise clients. It was not competing seriously with Amazon Web Services or Microsoft Azure for Fortune 500 contracts. Greene changed that. She unified Google for Work, Google Cloud Platform, and Google Apps into a single enterprise organization with integrated product, engineering, marketing, and sales functions. She built the sales infrastructure, closed the deals, and grew the business from approximately $2.1 billion in annualized revenue when she took over to $8 billion by early 2019.
In January 2019, she stepped down and was succeeded by Thomas Kurian, formerly of Oracle. She left the Alphabet board in June of that year.
"The world will be a better place with more female founders/CEOs. I want to encourage every woman engineer and scientist to think in terms of building their own company someday." - Diane Greene
In 2020, Greene was elected Chair of the MIT Corporation - the governing body of the Massachusetts Institute of Technology. The first woman in the history of the institution to hold that office. She now serves as Chair Emerita while maintaining an active portfolio of board work across multiple industries: payments (Stripe), enterprise software (SAP), tax and financial services (Intuit), web development (Wix), and global shipping (Maersk).
There is a pattern in this that she would probably resist over-analyzing. She has never been interested in legacy or narrative arc - she is described consistently by colleagues as one of the least self-promotional executives in Silicon Valley. Mark Leslie, a longtime VMware board member, described her defining trait as humility. Her own description of her greatest accomplishment at VMware: "Working with everyone to build it up."
What she cares about now, beyond the board work, is the pipeline. Specifically: the shortage of women founding technology companies. She gives talks. She mentors. She takes calls from female engineers and scientists who are thinking about starting something. She is not doing this because it is a good look. She is doing it because she looked around the room in 1998 and noticed who wasn't in it, and she has been thinking about that ever since.
The windsurfer who organized the world's first championship in a sport that barely existed, the naval architect who pivoted to software and built the technology that runs modern cloud computing, the CEO who was fired and came back and built something even bigger - she is not finished. She is mid-stride. You are catching up.
