Today, transformation consultants need to provide more than just brand-strategic advice. They need to be knowledgeable allrounders understanding the multifarious challenges companies face on their way from here and now to tomorrow and ahead.

They must be creative inspirers, progressive contrarians, passionate trend-scouts and digital-savvy future designers.
They must be where their clients are but with their heads in the future.
