    As founder and CEO of an established B2B service provider for the European energy market. I steer JAO through a politically dynamic and technically complex environment.

    I had the pleasure to start my career at JAO (previously CASC.EU) in 2011, and established later on the Financial Controlling department back in 2015 just before the company merger.

    I was appointed as Finance Manager in 2017 and joined JAO's Management Board in June 2020 as Chief Financial Officer. Together with my team, we have developed JAO’s financial services and various domains of expertise. We strive every day to solve financial complexities, bring added-value and efficiencies to our customers through financial solutions.
