Nick d’Aloisio has sold his app Summly to search giant Yahoo. The remarkable thing is that he’s still a student, only 17-years old, and thought of the top-selling mobile app for a content-shortening program while preparing for exams.

“I would have never imagined being in this position so suddenly,” he wrote on his website.

Summly is designed to condense content so readers can scroll through more information more quickly, which is useful for the small screens of smartphones. D’Aloisio said he is working how to invest the money from the sale, though his age imposes legal limits for now on his access to it. “I’m happy with that and working with my parents to go through that whole process,” he said.

D’Aloisio taught himself to code at age 12 after Apple’s App Store was launched. He created several apps including Facemood, a service which analyzed sentiment to determine the moods of Facebook users, and music discovery service SongStumblr. While he’s in the English equivalent of final school exams, he plans to continue his studies while also working at Yahoo’s offices in London.
