A couple of years ago I freelanced at a very small consultancy where one of the founders had been a design manager at some very large global consumer electronics brands (0ne of bepsters colleagues used to work with him actually ). On their website, he showcased some of these projects but in the description said "worked on whilst design manager at XXX with designers XXX).
It is one of those weird situations that you want to continue doing great work in your own firm that you did in the past whilst working for someone else.
Perhaps Michael could chime in on this since he must have faced something similar even though his new studio is under his name? He does not give the impression he solely designed all of the products.
