New Q2 data from Synergy Research Group shows that the enterprise SaaS market grew 31% year on year to reach almost $15 billion in quarterly revenues, with collaboration being the highest growth segment. Microsoft remains the clear leader in overall enterprise SaaS revenues, having overtaken long-time market leader Salesforce a year ago. Microsoft was already rapidly growing its SaaS revenues, but in Q2 its acquisition of LinkedIn gave its SaaS business a further boost. In terms of overall SaaS market rankings, Microsoft and Salesforce are followed by Adobe, Oracle, and SAP, with other leading companies including ADP, IBM, Workday, Intuit, Cisco, Google, and ServiceNow. It’s notable that the market remains quite fragmented, with different vendors leading each of the main market segments. Among the major SaaS vendors those with the highest overall growth rates are Oracle, Microsoft, and Google.
