The London office of Saffron, which describes itself as “the world’s smallest global brand consultancy,” is the big, white hangar you’d expect from designland. The people have that Euro world-citizen look: the women pared down, the men with heavy, pushed-back hair. No suits. No bling. It’s actually, to be more specific, haute Hispanic—Saffron, which also has offices in London, Mumbai and New York, started in Spain.
