At the turn of the 20th century, the now-defunct Waimea Sugar Mill Company was a publicly owned and traded company, and Faye began to purchase shares in it. By 1905, he was the President and largest stockholder of Waimea Sugar Mill Co. By 1915 or 1916, Faye owned the entire operation. In addition to operating his own businesses, in 1898 he helped merge three existing plantations into the Kekaha Sugar Company, and he became its first manager and Vice president, a position he held for thirty years, until his death in 1928.
