"The New York Times" has noted that Martínez's hometown, Monterrey, "is home to some of Mexico's largest industrial companies," with power being "heavily concentrated among businessmen in the so-called Group of 10, a club that includes the Sada family." Although Martínez "was not a part of that circle, he has cultivated deep connections to it," helping the Sadas in 2004, for example, when one of their firms went bankrupt, and, later, becoming involved in the bankruptcy of the Sada-owned firm Vitro. According to one source, Martínez's "paternal great great grandmother was the sister of the paternal grandfather of Adrian Sada."
