Celonis

celonis.com
Celonis is a software company founded in Munich in 2011 by three students who built a tool to work out why an IT helpdesk was slow, and in doing so helped create the process mining category. Its platform reconstructs how business processes actually run by reading event logs out of systems such as SAP, Oracle and Salesforce, then shows where work stalls, loops or leaks money against how the process was designed. Dual-headquartered in Munich and New York and valued above thirteen billion dollars, it sells to large enterprises looking to fix supply chain, finance and customer service operations without replacing the underlying systems.
