On March 26, 2007, Payoneer announced that Greylock Partners was going to invest $4 million in their company. I believe that the investment had some sort of performance requirements associated with the agreement because TechCrunch reported that Payoneer received the rest of the $3 million today.
The company was founded in 2005 and has an R&D facility in Tel Aviv, Israel. Current Payoneer partners include Metacafe, Amie Street, oDesk, and BitWine. And Payoneer recently announced that they have also partnered with iStockphoto.
