Best startups this year?

I’m prepping a post about the best tech startups this year. I’ll be dividing it into three categories: UK, Irish and European (as in, continental Europe). The idea is to look at both web and mobile startups which are doing interesting things.

As part of my research I thought I’d ask TechCrunch UK readers for your thoughts. Obviously I’m sure you’ll agree that YOUR startup was quite simply the coolest this year, but it would be more useful (and less sucky) if you suggested a company other than your own…

Ok, let’s hear it. Comments are welcome below.
