German based software company Celonis has raised $1 billion from investors to give the company a post-fundraising valuation of more than $11 billion, extending a record-stretching series of mega funding rounds by German technology startups. Munich-based Celonis, founded a decade ago, has consistently doubled revenue from year to year and recently launched its Execution Management System product that crunches data to tackle problems and automate decision making. On top of the Series D venture round, a record for a German technology startup, Celonis said it was hiring veteran Wall Street analyst and Google executive Carlos Kirjner to become its chief financial officer.
