Andrew Rosen is a pioneer in the contemporary fashion market, co-founding Theory with Elie Tahari in 1997.

Rosen sold the majority of his shares in Theory in 2003 to Japan's Fast Retailing, but retains an 11 percent share and continues to run the company. He has a particularly strong relationship with Theory’s owner, Tadashi Yanai , whose company also owns Uniqlo and J Brand.

Following the sale of Theory, Rosen invested $10 million dollars in emerging designers. Rosen's portfolio of investments includes Alice + Olivia, Rag & Bone and Proenza Schouler . Rosen also has stakes in Kiki de Montparnasse, Aiko, and Gryphon. By 2012, they had evolved into businesses with combined sales of over $300 million, prompting Vogue editor-in-chief  Anna Wintour to say, “We don’t have a Gucci or LVMH in this country, but in his own way, Andrew is creating a kind of American equivalent.”

Rosen was arguably the first to identify the gap in the United States and international markets for fashionable contemporary brands. In response to the shifting consumer market, Rosen hired designer  Olivier Theyskens , whose aesthetic was well-received in the Asian market, to head up Theory’s design team as creative director, as well as acting as creative director of the newly created Theyskens’ Theory, an advanced contemporary line. Olivier Theyskens has sicne left the company and the Theyskens’ Theory partnership has ended.


Believing the Chinese consumer "understand[s] Louis Vuitton , but they don't understand contemporary fashion,” Rosen has positioned Theory to be the first premium contemporary brands the Chinese consumer will understand. All who work with him reference Rosen’s geniality; the young designers he works with variably call him “friend” or “godfather.”

Rosen has a son and daughter.
