Business intelligence, or BI, is a blanket term for technology that helps companies organize and query their data to help them improve operations and make more money.

Infor, which makes accounting, finance, and manufacturing management software competes with Oracle and SAP (sap). And its CEO, Charles Phillips, formerly president of Oracle (orcl), isn't shy about taking on industry giants.
Last month, he formed a partnership with Marketo, the marketing technology company, to help it compete better with those companies as well asSalesforce (crm). All of those software companies trying to sell software to help marketing professionals target their pitches across email and other channels and then track how the campaigns do.

"The founders of Birst have a deep BI pedigree," Phillips said in a statement, adding that Birst's team including co-founders Brad Peters and Paul Staelin, previously built Siebel Systems' business intelligence technology. Siebel was bought by Oracle in 2006.
Birst claims such name-brand customers as American Express Global Business Travel, Kellogg's, and Schneider Electric.
