We are a consulting firm with one mother brand and 3 subbrands. We need a design for the morther brand and the 3 subbrands. Common for the company is that we are a hard core resultoriented firm within professional services. The 3 subbrands are KPI Communciations (advertisement agency), KPI Digital (web agency) and KPI Business (management consulting).
We used to be only KPI Communications. Recently we have done a lot of consulting and digital work, so we have decided to make them autonomous brands. We use an abstract mark as you can see from our past logo (see also our "old" website at http://www.kpic.dk). We would like to continue to use our symbol, but how is up to you. You can even modify it, if it makes sence.
It is important that the three subbrands have a clear association to the mother brand.
An abstract shape or symbol is used to convey the values of your business.
