Range extension
New references consistent with your existing line, custom-formulated.
Extending a line, reformulating to clean or organic, reshoring production, securing a supplier: all sensitive projects. We run them with the rigour of a partner who understands what is at stake for an established brand.

When a brand already has customers and a reputation, every change is a risk to manage: a reformulation that alters the sensory feel, a new supplier that shifts quality, a range extension that has to stay coherent. We bring the R&D and production that make these moves safe.
