This document discusses product strategy and how companies can combine products through co-branding or ingredient branding. It defines co-branding as combining different products into a joint product or marketing them together. There are three types of co-branding: same company co-branding, joint venture co-branding, and retail co-branding. Ingredient branding is creating brand equity for products contained within other branded products. Successful co-branding and ingredient branding require ensuring a logical fit between brands, adopting due diligence, and making the customer understand the value of the products or ingredients.
