Digital money platform Uphold has bought a mobile commerce startup, the company announced Thursday, coming soon after it inked a multi-million dollar investment. Uphold has bought Cortex MCP, a deal that will see the company - formerly known as Bitreserve - acquire Cortex's intellectual property holdings and add its founder Shaunt Sarkissian to the Uphold payments unit. Through the Cortex acquisition, Uphold said it will support "a new closed-loop payment platform expansion," with a focus on Central America and South America. "Cortex's mobile centric, closed loop payment and secure tokenization solutions provide industry leading technologies and security to our platform. It additionally brings new commercial offerings and opportunities to our enterprise division, Uphold Solutions," William Dennings, Uphold's COO, said in a statement.
