Featured Client
Built by ecommerce founders, for ecommerce brands.
Silver Mushroom is where the CK Fulfilment story began. Founded by Rebecca Kane, the ecommerce homeware brand grew from a small bedroom business into a thriving online retailer. As demand increased, the challenges of outsourcing fulfilment revealed just how much the right logistics partner can influence a brand's growth and customer experience.
Those first-hand experiences inspired the creation of CK Fulfilment; :a business built by ecommerce founders, for ecommerce brands.
Today, we help ambitious businesses across the UK and Europe scale with confidence, combining experienced people, proven processes and intelligent technology with the personal approach that has been part of our journey from the very beginning.
