99designs is a MUST USE service when creating your company, whatever the type of company. We've not only got hundreds of design suggestions from dozens of designers, but mostly ended up with a name change and a real identity for our company while just looking for a "simple logo". It really helped us to better define our project and ended with a fantastic logo where now people immediately get who we are just looking it! Add to this a great support team and you'll get why 99designs is a MUST USE service.
For sure I'd never create any other company without using 99designs first!
