    Frederik Johnsen

    Chairman of the Management Board

    I  joined JAO (previously CASC.EU) in 2008 as one of the first employees in the operations team. Appointed as Operations Manager in 2009 I have helped the company’s growth to its position of the single European Auction Office.

    Following the merger of CASC.EU and CAO and the creation of JAO SA in 2015, I have taken over the Business Development Manager responsibilities. On March 1, 2023, I took over the duties of the CEO.

  • Chief Financial Officer

    Diana Rodrigues

    Member of the Management Board

    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.
