PAUL Tech goes on the offensive as a heat supplier and strengthens its Management Board
Klaus Schmidtke

PAUL Tech AG has appointed Thomas Körfer (pictured right) as Chief Technology Officer and Patrick Weiden (pictured left) as Chief Financial Officer. This expands the existing Management Board team to include Sascha Müller (CEO), Oliver Schwager (Chief Operations Officer) and Thomas Eusterholz (previously Chief Technology Officer, in future Chief Digital Officer). With this step, PAUL is preparing for a significant growth phase in the course of the product expansion with PAUL Net Zero, which will lead the company into a new role as a heating provider.
In view of the growing challenges, the former Technology division will be split into two departments: Hardware Development and IT Administration will remain the responsibility of Thomas Eusterholz. Thomas Körfer will be responsible for Think Tank, Data Science & AI, UX, IoT and Framework Development as well as DevOps. He brings over 15 years of experience in digital transformation and data-driven IT solutions, most recently as Managing Director at BCG Platinion.
The heating transition needs technology as an accelerator. With our innovative AI for controlling our heat pump and heat distribution in buildings, we will open a new chapter in intelligent and sustainable heat supply. I look forward to driving this development forward with my team.
Thomas Körfer, CTO PAUL Tech AG
In view of the company's ambitious growth targets, the Finance division will be expanded into a new Management Board department and Patrick Weiden will be appointed Chief Financial Officer (CFO).
Patrick Weiden has over 20 years of experience in investment banking, financing, investor relations and M&A. Most recently, he was a member of the Executive Board of an SDAX company.
I am delighted to be able to accompany PAUL in this exciting phase of transformation and growth. The scalability of our business model combined with the stable cash flows from heat supply offers an exciting story for equity and debt investors.
