MarketLink Inc., a leading provider of outsourced teleservices solutions based in Des Moines, has been acquired by Allied Global LLC, a privately held company based in Bensalem, Pa. The transaction, the terms of which were not disclosed, will "merge two successful companies creating a stronger, larger, and more robust full-service contact center offering inbound, outbound, email, and chat service," the companies said in a release. With the addition of MarketLink, which employs nearly 500 people in seven Midwest call centers, Allied Global has more than 6,000 employees working in 19 contact centers in four countries. MarketLink will continue to operate under its own name.
