People make projects, not the logo they adorn.
I've worked with and built solutions for household brands, bluechip companies and bright eyed startups but I don't tend to retain clients in the traditional sense (like they are badges of honour), I prefer to work on specific problems or projects that require my unique touch.
But since I'm sure you are interested, since company inception in 2008 I've worked with some talented people at Matt & George, Margaret Howell, Tipped, The Walt Disney Company, Omobono, Royal Television Society and O2. And of course the mega chaps at Ideapi.
Before then I worked on projects for Twentieth Century Fox, BBC, Hit Entertainment, Disney Consumer Products, Nickelodeon & Entertainment Rights.
