He bought a deli at 16, talked a German software giant into hiring an American CEO, and is now building an AI platform that runs nearly every large company on earth.
The summer of 1977, a 16-year-old from Amityville, Long Island shook hands on a $7,000 promissory note and became the owner of a delicatessen. No collateral. No credit history. Just an argument: "If I don't make the payment, you own all the stock." He talked suppliers into extending credit, created delivery routes for senior citizens before apps existed, built a video game corner that made the store the default after-school destination, and opened a charge account for blue-collar workers who got paid every two weeks. He had not yet taken a single business course. He was running customer segmentation by instinct.
Bill McDermott is now Chairman and CEO of ServiceNow, the cloud platform that has quietly become the operating system of corporate America. Nearly 90% of Fortune 500 companies run on it. The renewal rate sits at 98% - meaning almost no one who signs up ever leaves. Since McDermott joined in November 2019, revenue has tripled. In 2024, ServiceNow became the first enterprise software company in history to cross $10 billion in annual revenue without acquiring revenue through M&A and without mass layoffs to goose the margins.
Before ServiceNow, there was SAP. McDermott arrived at the German software giant in 2002 as president of SAP America, ascended to co-CEO in 2010, and by 2014 was sole CEO - the first American ever to run SAP. He found a company worth $39 billion and left it worth over $156 billion. He doubled revenue. He led the transition from perpetual licenses to cloud subscriptions at a company that had been built on the old model for decades - the equivalent of convincing a railroad to lay its own tracks on the interstate. His exit in 2019 prompted enough applause from the German business press that Handelsblatt had already named him Manager of the Year in 2016.
McDermott arrived at ServiceNow with a specific conviction: enterprise software companies were dramatically underestimating how much value they could unlock by making work actually work. Companies were drowning in disconnected systems, manual approval chains, and digital processes that existed in PowerPoint but not in practice. ServiceNow's platform promised to wire those gaps shut. McDermott's job was to make the world believe it.
He made the world believe it by doing something rare in tech: treating growth as a people story rather than a product story. His first act at ServiceNow was to spend weeks in one-on-one conversations with employees across the company. Not listening-tour theater - actual conversations. He has said publicly that his management philosophy rests on a single word: trust. Not trust as a soft concept, but trust as a mechanism. When leaders earn trust instead of imposing authority, they stop having to push people and start having them pull toward something. The 98% renewal rate is, in part, a trust number.
The current chapter is AI. McDermott identified AI as ServiceNow's next defining wave before most enterprise software companies had updated their marketing decks. Now Assist, the company's AI suite, hit $600 million in annual contract value by the end of 2025. ServiceNow has moved beyond generative AI novelties into what McDermott calls the "agentic AI" era - autonomous workflows that don't just answer questions but complete processes. The $2.85 billion acquisition of Moveworks brought agentic AI capabilities into the platform. The $7.75 billion acquisition of Armis added cybersecurity intelligence. AI revenue is tracking toward $1 billion by the end of 2026, and McDermott has publicly committed to remaining as CEO through 2030.
In February 2026, he announced he would personally purchase $3 million in ServiceNow stock at the earliest date permitted under insider trading rules. He called it "a once-in-a-generation moment." CEOs say things like that in press releases. Buying $3 million of stock with your own money says something different.
McDermott is an Irish-American from a family with no shortage of competitive spirit. His grandfather Bobby McDermott played basketball in an era before the NBA existed, and the Naismith Memorial Hall of Fame decided that mattered enough to enshrine him permanently. Bill McDermott grew up on Long Island understanding that outcomes were earned, not assigned. He delivered newspapers at 11 before he owned the deli at 16. He got to Xerox with a 100-day plan already written before anyone offered him the job. He ranked first in every sales role he held at Xerox for 17 years and became its youngest corporate officer at 36. He went to SAP after 17 years at Xerox, stayed 17 years at SAP, and is now deep into year six at ServiceNow with no indication he intends to stop.
His memoir, "Winners Dream," won the gold medal Axiom Business Book Award and distills a life philosophy that could be summarized as: the process is the point. Winning, for McDermott, is not a destination but a direction - a commitment to becoming a better version of the thing you already are. Kinder. Hungrier. More humble. More audacious. He is not describing a tech company's OKRs. He is describing a way of being in the world. That it happens to produce exceptional business outcomes is, by his account, the mechanism, not the coincidence.
Glassdoor has named him a top CEO in four countries simultaneously - the United States, Canada, the United Kingdom, and Germany. Those are four very different workforces with four very different cultures. The denominator that keeps producing the same numerator is the person running the company.

McDermott bought Amityville Country Delicatessen for $7,000 on a promissory note with a simple guarantee: "If I don't make the payment, you own all the stock." With no capital, he talked suppliers into extending credit, designed a delivery program for seniors before the concept had a name, created installment credit for blue-collar workers, and installed video games to capture the after-school crowd. He turned three separate demographics into loyal customers through segmentation before he'd ever heard the word.
When McDermott interviewed at Xerox, he walked in with a fully prepared 100-day plan - what he would do, how he would do it, and what the result would look like. He promised to build the top new-business sales team in the country. They hired him on the spot. He then spent 17 years proving the plan was understated.
In July 2015, McDermott slipped on stairs at home while carrying a glass of water. The glass shattered on impact. A shard went through his left eye. He underwent more than a dozen surgeries and permanently lost vision in that eye. He was back at SAP's headquarters leading the company within months, the same year.
In February 2026, McDermott announced he would purchase $3 million of ServiceNow stock - not through compensation mechanisms or a stock plan, but personally, with his own money, on the earliest date permitted under insider trading restrictions. He said: "This is a once-in-a-generation moment with ServiceNow." The announcement moved the stock.
"Winning was the process, not the destination. A journey of striving to be better - to be kinder, more compassionate, hungrier, more humble, more audacious, more inspiring, more rigorous - that was what turned me on."- Bill McDermott, "Winners Dream"
"Leadership is about helping people see that the world is a bigger opportunity."
"What you focus on expands. Focus on what you are best at and you will be unstoppable."
"Leaders in this era are best defined by humility."
"If a vision is not supported by the workforce, even the most brilliant ideas risk being nothing more than lightbulbs in a basket."
"You treat people with dignity and respect and they give it right back to you."
"If a person has the dream and the drive, you can teach him or her a lot. I'm less susceptible to the person who has the pedigree and the right answers, but who is looking for me to give them the dream and the drive."
"Power doesn't come from a title."
"Purpose can only scale if it's enabled by one team with one dream."
"This is a once-in-a-generation moment with ServiceNow."
His grandfather Bobby McDermott is in the Naismith Memorial Basketball Hall of Fame - considered one of the best long-distance shooters of the 1930s and 1940s, before the three-point line existed.
At 16, he owned a working deli, having negotiated supplier credit with no track record. His customer loyalty programs predate the concept by decades.
He was the first American-born CEO of SAP - a 50-year-old German institution. The Handelsblatt named him Manager of the Year while he was doing it.
ServiceNow is the only enterprise software company to reach $10B+ in annual revenue without acquiring revenue through M&A - and without mass layoffs to manufacture the margin.
His memoir "Winners Dream" won the gold medal Axiom Business Book Award. The core argument: winning is a process, not a destination.
In February 2026, he purchased $3 million of ServiceNow stock personally - on the earliest legally permissible date under insider trading rules.
He has been named a top CEO by Glassdoor in four countries simultaneously: USA, Canada, United Kingdom, and Germany. Four cultures, one number.
He ranked #1 in every single sales position he held at Xerox. Over 17 years. Without exception.
He has led two companies - SAP and ServiceNow - through complete cloud business model transformations. Few executives have done it once. He's done it twice.
