Altisource Portfolio Solutions S.a.
A provider of services, software, and an online auction marketplace for the mortgage and real estate industries, Altisource helps lenders, servicers, and investors manage everything from loan origination to foreclosed-property sales, with tools like the Hubzu auction site and Equator and RentRange software. It was born in 2009 as a spin-off from mortgage company Ocwen Financial (now Onity Group), a move orchestrated by founder William Erbey. Fun fact: its name is widely read as a blend of "altitude" and "source," a nod to being a high-level one-stop shop for back-office mortgage work.
