According to "The New York Times", "Martínez is, even to his associates, something of a mystery," a man about whom "Little is known….In life as in business, Mr. Martínez treads lightly. He is fond of shell companies, whether to buy artwork or to pay household expenses. Those he hires often know him only as 'the client.'" Noting that "it is unclear" how much money Fintech controls, "or even how many employees work there," the Times has reported that when Elliott Associates and other funds sought to sue Fintech, they "encountered one obstacle early on: they couldn't find Mr. Martínez," either at Fintech's Park Avenue offices or at his Time Warner Center apartment.
