A south London schoolboy has just sold his company to Yahoo in a multimillion dollar deal. He’ll be their newest and youngest employee and he isn’t even 18 yet. So what did you do today?Nick D'Aloisio built Summly from his bedroom when he was just 15 and soon attracted big investors like Horizon Ventures, the private technology investment company of Hong Kong billionaire Li Ka-shing — which also backed the likes of Facebook, Siri and Spotify.The $300,000 investment arrived on Nick’s 16th birthday, making him one of the youngest people ever to attract venture capital funding. He also received backing from celebrities like Ashton Kutcher, Stephen Fry and Yoko Ono for a total of $1 million by the time he launched.Summly makes a mobile app that condenses news articles into three key paragraphs that fit onto an iPhone screen, allowing readers to scroll through information more quickly. Users can customise the news categories, and link to the original article if they like the summary.“I designed Summly because I felt that my generation wasn’t consuming traditional news anymore,” said Nick.The prototype was downloaded more than 150,000 times and was chosen by Apple as its App of the Week in the UK and other countries.Mr D'Aloisio, who taught himself to code at age 12, created other apps before Summly. FaceMood, for example, took someone’s Facebook status and analysed it to decide the mood of the user.Now, Yahoo is buying Summly and while the price was not disclosed, AllThingsD has reported it was a $30 million deal — 90 percent in cash and 10 percent in stock.Mr D'Aloisio who lives with his family in Wimbledon, told The Telegraph he had "boring" plans for the money. "I'm planning to invest it — my parents are in control of it," he said.Mr D'Aloisio is now 17, making him younger than Yahoo, which was incorporated in March 1995. He will now work for Yahoo CEO Marissa Mayer and become the company’s youngest ever employee.Although the Yahoo acquisition won't close until later this spring, Mr D'Aloisio said that Summly will no longer be available. Summly's technology will return in other Yahoo products, Mr D'Aloisio wrote in a Monday blog post.Mr D'Aloisio will work for Yahoo in its London office. Two other Summly workers will join Yahoo at its Sunnyvale, California, headquarters.The deal is Yahoo’s fifth small acquisition in the past five months. All of them have been part of Ms Mayer’s effort to attract more engineers with expertise in building services for smartphones and tablet devices — an increasingly important area of technology that she believes the internet company had been neglecting.
