He's lately begun taking meetings with the likes of Marissa Mayer and Rupert Murdoch. (Murdoch is chairman of News Corp, which owns The Wall Street Journal.) Though D'Aloisio's net worth at this point is merely eye-popping, not obscene, in his own youthful way he seems every bit as formidable as relative gray-hairs like 27-year-old Tumblr founder David Karp or 29-year-old Facebook wunderkind Mark Zuckerberg. "He captivates a room," says Joshua Kushner, founder of Thrive Capital, an early backer of Summly. "He is incredibly self-aware for his age."

D'ALOISIO BEGAN designing iPhone apps nearly the moment the app store opened in 2008. He was 12 years old, working on a Mac in his bedroom in the London district of Wimbledon. Because he was too young, he signed up for the Apple developer's license using his father's name. He'd taken no formal computer science classes at school, and neither of his parents (Diana and Lou, a lawyer and a business executive, respectively) knew much about tech. Instead, he learned how to program almost entirely by himself, scouring websites and watching instructional videos. 

His first coding effort resulted in an app that played audio snippets from speeches by his idol, Steve Jobs, whose unauthorized biography he'd recently devoured. "It was rejected by Apple for every reason," D'Aloisio says now, laughing. "Copyrighted audio, poor functionality, too simple." Another early design allowed users to touch a picture of wood, producing a knocking sound. A third transformed a smartphone screen into a treadmill for your fingers. That one earned about $120 in sales on its first day.

When he wasn't programming or doing schoolwork, D'Aloisio began to fill his spare time reading about natural language processing. He'd studied languages as diverse as Latin and Mandarin, and became fascinated by concepts like grammatical frameworks, morpheme parsing and the 1960s work of the linguist Richard Montague. "He's my favorite," D'Aloisio enthuses. "He theorized that natural language could be described like a syntactical programming language." 

As he scanned the Internet for knowledge, D'Aloisio decided that what he really needed was a better way to determine, at a glance, what was worth reading. He envisioned a summarization tool that used language theory to give a meaningful synopsis in fewer than 400 characters.

"There are two ways of doing natural language processing: statistical or semantic," D'Aloisio explains. A semantic system attempts to figure out the actual meaning of a text and translate it succinctly. A statistical system—the type D'Aloisio used for Summly—doesn't bother with that; it keeps phrases and sentences intact and figures out how to pick a few that best encapsulate the entire work. "It ranks and classifies each sentence, or phrase, as a candidate for inclusion in the summary. It's very mathematical. It looks at frequencies and distributions, but not at what the words mean."

An early iteration of Summly, called Trimit, was featured in Apple's app store in July 2011 on a list of new and noteworthy offerings. There it was noticed by the influential Silicon Valley blog TechCrunch and quickly came to the attention of an investment group led by Li Ka-shing. When D'Aloisio was approached over email by Li's people at Horizons Ventures, he was only 15—and so far mostly managed to conceal that fact. He'd never met with anyone in the tech world face to face, and the information he'd listed when he registered Trimit spoke only vaguely of a London technology company. It failed to mention that the company's management and technology teams—in fact, its entire workforce—consisted of a single kid in a suburban bedroom who wasn't yet old enough to drive. 

"I thought I was going to sell the app in the Apple store for a pound or two each, and then I'd use the money to buy a new computer," says D'Aloisio. "I'd never had any contact from an investor before. And now here's an email supposedly from a Hong Kong billionaire. It sounded dodgy. I didn't respond the first time. They had to email me again." D'Aloisio was accompanied by his mother and father ("they were a bit bewildered, it was kind of insane") as he took a meeting with Horizons Ventures's representatives in London in August 2011. The meeting ended with D'Aloisio receiving a seed investment of $300,000.

As fall arrived and school began, D'Aloisio felt immense pressure to deliver for his backers. He needed to whip his algorithm into better shape, so he contracted a team of Israeli coders who specialize in natural language processing. Searching on Google, he found and hired a retired professor living in Thailand who'd written seminal books on the topic. "He became our main scientist," says D'Aloisio. "He now works at Yahoo! in the Sunnyvale office."

Meanwhile, he was being ferried around the globe to tech conferences, getting introduced to other potential investors. D'Aloisio made a remarkable impression on everyone he crossed paths with. "He has an eerie maturity," says Andrew Halls, headmaster of the King's College School in Wimbledon, which D'Aloisio has attended since he was 11. "He has an extraordinary articulateness in the face of situations that, for me, even as a 54-year-old, might be terrifying."

"I was blown away by him," Kushner recalls. "The first time I interacted with him was at News Corp, when he was meeting with Murdoch, and I was looped in to provide perspective. Nick described the vision of what he was trying to accomplish. And he was providing insight to Rupert." D'Aloisio's stage presence, coupled with the deep-pocketed credibility brought by Li, attracted a large group of benefactors to Summly, including Ashton Kutcher, Yoko Ono and Stephen Fry.

D'ALOISIO HAS BEEN quoted opining that "time is the new currency." It's the driving notion behind Summly. It's also a strangely wise observation from a 17-year-old. At that age, many of us had more time on our hands than we knew how to fill without plummeting into severe boredom. It's easy to forget—conversing over lunch in a London café or strolling through the Tate Modern—that D'Aloisio was born in 1995 and has not yet graduated from high school. Or that he still lives in his childhood bedroom, in a cozy upper-middle-class home. As I chat with his parents, he excuses himself to work on his computer. Slouching down the hall in his stocking feet, hems of his skinny jeans brushing the hallway carpet, it is the most kidlike you will ever see him.

D'Aloisio's parents came to England from Australia. His father, Lou, has worked in commodities for BP and Morgan Stanley, while his mother, Diana, is a corporate lawyer who also serves as her son's contractual representative. They always knew D'Aloisio was an extremely inquisitive child. "But he was our first, so we didn't think it was anything out of the ordinary," says Diana. (D'Aloisio's brother, Matthew, is 14.) They stress that despite his impressive accomplishments, he remains a normal kid. Or at least as normal as a kid can be when he's making offhand references to Markov models and stochastic processes. "He still goes out on weekends, still goes to parties," says Diana. "He's got a girlfriend. All the things you do at 17."

D'Aloisio himself strives to maintain a bubble of normalcy. He dates the same girl he did before the whirlwind hit. And though he's stopped attending school—he's too busy to sit in class while overseeing Summly's development—he still gets his work from his teachers and meets with them regularly. He cherishes the fact that his circle of friends knows little of his life as a budding industrialist. When I met him, he was about to head to Greece for a weeklong vacation with a pack of high school pals. 

For now, D'Aloisio isn't touching the money. "I'm too young to appreciate the value of it," he insists. "I don't have a mortgage, I'm 17. To me, a hundred pounds is a lot. Take that as a benchmark." Though he's not allowed to comment on Summly's sale price, when pressed he allows that he might one day like to deploy his newfound riches as an angel investor. No one around him seems to think there's a danger that the money will ruin him or that he'll be tempted to spend the rest of his life dissipating on a beach. "He's pretty well grounded. You wouldn't believe how frugal he is," says Diane. "He's got a great engine," says Lou. "He won't stop at this."

But there's little doubt this was also an "acqui-hire," in which the person being bought is just as important as the product. D'Aloisio is now working full time in Yahoo!'s London office, and his youth, his energy and his undeniable it-factor have brought the formerly musty tech giant a much-needed injection of cool. Yahoo! CEO Marissa Mayer —who lends the company some of her own it-factor—praises his "commitment to excellence in design and simplicity" and says she is "inspired by the creativity and tenacity Nick brings to his work."


As for his own education: He's weighing whether to enroll in university in England or maybe the U.S. to be closer to Silicon Valley. Or perhaps he'll skip college entirely and just focus on his work. "I absolutely want to start another company," he says. "Serial entrepreneurs get addicted to creation. I want to be passionate. I feel really bad when I'm not doing something new."
