In a nutshell, Macadamian is a software and design company. Rather than taking on the mega-task of designing their own site, they decided it would be easier to contract it out. (I can totally understand — branding oneself, as a designer, is always the hardest).
The site needed to reflect who they are as a company. They fancy themselves as quirky, industry leaders and hope to recruit, add legitimacy and generate leads with the redesign.
