Germany based enterprise software giant SAP is reported to have purchased customer identity firm Gigya for a reported $350m. Gigya today manages some 1.3 billion customer identities across hundreds of sites, existing business that it will bring under SAP’s umbrella. The idea will be to integrate those features into SAP’s wider e-commerce operation to expand the kinds of services it offers to existing customers, and to help sell more e-commerce services to Gigya’s base.
