Nunwood said its decision to launch Fizz in the US stems from a belief that the market is seeking smarter, more cost-efficient systems.
Fizz has been shortlisted for an Explor Award for its work with Orange.
Nunwood launched in the US in 2007. Since then its international business has grown by 30%. This has been driven by a series of client wins including Wyeth Nutrition, Georgia Pacific and Saks.
Fizz director Luke Allan said: "The needs of global businesses are changing dramatically. New market intelligence and customer engagement techniques are no longer top of the agenda.
"Today’s marketers are demanding better integration and use of existing knowledge, with joined-up, accessible use of the right information."
