I like playing sport. I'm a bit of a design enthusiast, and like spending time with my girlfriend and mates.

It's the scale that Yahoo brings - and that user base - that I really want to build products for.

My motivation has always been to do technology apps and companies, not making money. Just because the money's come, nothing's changed.

Yahoo to me, as the founder of a company, is one of the biggest opportunities you could have; it's one of those classic Internet companies.

I put together an iPhone app called TrimIt and released that in July 2011. About a month later, the private fund of the Hong Kong billionaire Li-Kashing cold emailed me and expressed an interest to invest, but they didn't realize I was 15. They thought it was a U.K. company with a team.

I thought of the idea of Summly in March or April 2011. I was 15 years old and I was revising for some kind of history exam. The problem was I was trying to find information that was useful to me. When you type into Google an esoteric term, you get quite a lot of stuff that's not relevant.

I was using Twitter a lot on my phone, and was realising there was a massive gap between the link on the tweet and the full story. If you could come up with a summary layer to show in Twitter, that would be awesome.

My first app was released in July or August of 2008. It was a 'fingermill' - a treadmill for your fingers. My level of programming was quite basic to begin with, so it was more gimmicky to start with. Day one it was up there, I had 79 pounds worth of revenue.

One thing I'd like to do is angel investing in small companies. That's what's exciting, and if you are lucky to have a bit of money, you can take those risks.

The App Store has democratized the creation of content. As a 12-year-old kid, I was able to put my application on the store. No one knows who's behind the screen so you can't tell I'm a 12-year-old.

There is a generation of skimmers. It's not that they don't want to read in-depth content, but they want to evaluate what the content is before they commit time. Especially on a mobile phone - you don't have the phone, or cellular data, or screen size to be reading full-length content.
