    Building future brands better, bolder and faster. Everything you need, nothing you don't.

    We're a creative first branding, marketing and advertising agency working worldwide with the brands of the future. Services include; Branding & Positioning, Brand Design, Go-to-market Strategy, Performance Marketing, Content and Creative Advertising Campaigns. --------------------------------------------------------------------------------------------------------------------------- We now live in a world where technology has put men on the moon, replicated the beginning of time and made human hearts from scratch.  It’s also helped us work quicker, faster and more flexibly than ever before.  Sadly the vast majority of marketing, branding and creative agencies have failed to keep pace and for supposedly ‘innovative’ organisations they’re lightyears behind the unicorns of Silicon Valley.  For talent, it sucks to work for one of these dinosaurs because it means you’re overworked and undervalued.  For clients, it’s frustrating to work with one of these fossils because it means you’re overcharged and they underdeliver.   Something had to give.  We founded °Small World to change this. We believe that in a world where monkeys can play pong with their mind alone, we should be able to build an agency for the brands of the future.  We’ve created a new model of agency that unshackles the best strategic and creative minds in the world from the four walls of traditional agencies. We build and manage remote teams from a global 500 strong pool of top-notch talent to offer an unmatchable agency service for brands that need a fresh way of doing things.    Everything you need, nothing you don’t.
