Bastian Nominacher

Overview
Bastian Nominacher 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 Alexander Rinke and Martin Klenk as a spin-off from the Technical University of Munich and has remained in top leadership since. As co-chief executive he is particularly associated with the operational and structural side of the business, with responsibilities across finance, operations, human resources, security, and strategy, and leadership of European and Asian regions.
Why this entity matters
Nominacher is one of the founder-operators behind a company that reached a peak private valuation of roughly 13 billion United States dollars and helped define the process-mining and process-intelligence category, making him a recurring reference point in discussions of whether Europe can build and retain large independent software champions. His significance is reinforced by the operational nature of his leadership: unlike co-founders focused on product or external representation, he anchors the internal machinery of a rapidly scaling company.
Career, company, or institutional background
Nominacher's career is tied to Celonis, which grew from a Technical University of Munich student project on customer-service processes for broadcaster Bayerischer Rundfunk, where the founders realized logged system data could be reconstructed to reveal process inefficiencies. Early on he focused on building and running the organization, and in the co-leadership model he and Rinke served as co-chief executives with Klenk as chief technology officer. He guided Celonis 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
Nominacher functions as a co-leader of a category-defining enterprise software company and a representative of the operator-founder model, often cited for how founding teams divide responsibility to manage growth. As a co-founder of a company that reached 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 contributes to the region's reputation as a source of globally significant technology companies.
