The largest U.S. marijuana company received hundreds of millions of dollars in funding from Roman Abramovich in its early years, but the Russian billionaire is long gone, Curaleaf Holdings Inc.'s chief executive said. Boris Jordan. The leaked documents show that Abramovich funded Palliatech, the company that became Curaleaf in 2018, as well as Measure 8, a cannabis-focused venture capital firm founded by Jordan. Company spokeswoman Tracy Brady said Abramovich has no ownership or influence over the company. “Massachusetts regulators have already closed their investigation into this very matter after concluding that what we have consistently argued; No undisclosed control or ownership by any foreign investor exists and Curaleaf has complied with all relevant rules and regulations.”
