The group responsible for bringing multinational retail corporation Wal-Mart into the era of mobile and social commerce has just expanded. WalmartLabs, the retail giant’s eight month-old social and mobile product incubator, has acquired Small Society to help improve customers’ mobile experiences, the group announced Wednesday. Terms of the deal were not disclosed.

Small Society is behind several recognizable customer-centric applications for iPhone for brands such as Starbucks, Zipcar and Whole Foods.

“We believe that mobile can have an impact on every part of the shopping experience for Walmart customers, whether in-store or online,” WalmartLabs head Anand Rajaraman explained in a blog post detailing the reasons behind the acquisition.
