SAP expands its cloud software arsenal by acquiring hybris, a top provider of e-commerce infrastructure software, for an undisclosed sum. The deal comes 8 months after SAP bought top B2B marketplace provider Ariba. SAP argues hybris' software, which covers Web, mobile, and in-store channels, will improve "customer insight and engagement" when paired with its Hana in-memory database and Jam social networking software. The deal could spell tougher competition for hybris rivals Demandware (DWRE -0.5%) and NetSuite (N -0.4%). SAP could also end up competing with IBM, which has been making acquisitions to bolster its Smarter Commerce initiative.
