This is what I will do in this situation: 1. Keep the "Parent Brand" going. In this case, Mobile Jazz. Have the mobile jazz website list all your "children" brands including Product ABC or Service XYZ whatever. Make a portfolio page showing all the children brands on this site (children can be product or service) 2. For each "child" brand (which is a product or service), setup their own website separately and market them as needed. On the footer of the website somewhere, mention the parent brand as "ABC is a sister/child company under Mobile Jazz". Also perhaps on an "About" page of the child brand, mention Mobile Jazz as the parent to establish more trust and reputation. That way, you establish the individual products/services as their own brand but still link them all with Mobile Jazz. If a child brand becomes huge, no problem. It still has its own branding anyway. Fun fact: Did you know that the popular invoice service called "Freshbooks" is actually a child of "2NDSITE Inc". I remember freshbooks used to have this in their footer but now they have it in their terms and conditions.
