Alexander Rinke

Overview
Alexander Rinke is a German technology entrepreneur and co-founder and co-chief executive officer of Celonis, the enterprise software company widely regarded as the leader in process mining and process intelligence. He co-founded it in 2011 with Bastian Nominacher and Martin Klenk as a spin-off from the Technical University of Munich and has remained in top leadership since. Born around 1990, he was in his early twenties at founding, and as co-chief executive is closely associated with its commercial expansion, its growth in the United States, and its positioning as a category-defining vendor.
Why this entity matters
Rinke is one of the most prominent founder-operators to emerge from the German technology ecosystem in the past fifteen years, co-leading a company that reached a peak private valuation of roughly 13 billion United States dollars and helped define an enterprise software category. He is a recurring reference point in debates over whether Europe can build and retain globally competitive software companies, and a spokesperson for the thesis that operational efficiency hidden inside existing processes is a large, underexploited source of value.
Career, company, or institutional background
Rinke's career is bound to Celonis, which grew from a Technical University of Munich student project to improve customer-service processes for the broadcaster Bayerischer Rundfunk, where the founders realized system data on how processes ran could be reconstructed to expose inefficiencies. Taking a commercially oriented role, he drove international expansion, particularly into the United States, within a co-leadership model with Nominacher and Klenk. He steered the company through funding rounds culminating in a roughly 13 billion dollar valuation in 2022, and together with his co-founders received the Deutscher Zukunftspreis in 2019.
Role in the startup, technology, investment, or innovation ecosystem
Rinke functions as the visible leader of a category-defining enterprise software company and an advocate for the process-mining thesis, and as a founder who scaled to a multibillion-dollar valuation he is an influential reference figure in European venture and growth capital. Because Celonis originated at the Technical University of Munich, his success is frequently invoked as evidence of the region's capacity to produce globally significant technology companies, and he contributes to dialogue on process intelligence and enterprise AI.
