We have to provide our clients with a completely impartial view of the Platform marketplace.  No two retailers are in the same place on evolution of their online scale, multi-channel needs and customer needs so the solution needs to fit them well.  Some of the Recent platforms we have worked with for clients are:

Magento Enterprise on a Robinsons equestrian re-platform and Harvey Nichols

BT Fresca on Matalan and TJ Hughes

Cshop on Chums and Hobbycraft
