Profile
An executive perspective on transformation, digitalisation and growth.
Jan-Christoph Wiemann combines almost 20 years of experience in the energy and real estate sectors with operational managing-director and P&L responsibility. As COO of a corporate group, he was responsible for the holding company and 13 portfolio companies with around 500 employees.
His focus is on the process digitalisation and transformation of organisations: from developing clear target operating models and introducing digital processes to embedding them sustainably in day-to-day operations. International product management across more than 23 markets, scalable business models and the delivery of buy-and-build and post-merger integration strategies complement this experience.
Change management is not a supporting activity, but a key success factor: together with leadership teams and employees, change is designed so that new structures, technologies and products are embraced in practice.
