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

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.

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

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.

Be fearless and don't be afraid of failure. There is no better way to learn than through trial-and-error.

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 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.
