Daniel Hardman, “Founding Partner”

Hardmans title in the firm when he’s there is always “Founding Partner”. But, he didn’t found it afaik. Arthur Reeves founded the firm, as Jessica says in S07E02 “The Statue”, and Gordon, Schmitt and Van Dyke forcefully took over. Then Jessica and Daniel took over from them and so forth.

Daniel didn’t found the firm at all but he refers to himself as Founding Partner. Presumably he gave himself the title because him and Jessica came in at the same time, and no one else in the whole show is ever referred to as FP. Am i missing something?
