PRESS RELEASE
Karsten Dümmler, founder and long-standing Chairman of the Management Board of Netfonds AG, is stepping down from the Supervisory Board at his own request
Hamburg, 10 July 2026 – Netfonds AG announces that Karsten Dümmler, a member of the Supervisory Board, will step down from the company’s Supervisory Board on 12 July 2026 at his own request. The company’s co-founder will thus leave the active committees of Netfonds AG after more than 25 years of successful service.
Since the company’s founding in 1999, Karsten Dümmler has significantly shaped the success story of Netfonds AG – initially as Managing Director, then as a member of the Management Board following the conversion into a stock corporation (AG) from 2009, and as CEO until June 2021. He subsequently joined the Supervisory Board to continue providing strategic guidance to the company.
The successful conclusion of a major chapter
As a member of the Supervisory Board, Dümmler also played a decisive role in driving Netfonds’ strategic development forward. This year, the decision was finally taken to pursue future growth in partnership with a strategic financial investor. Following the successful entry of the new shareholder, Dümmler is now clearing the way on the Supervisory Board for the next generation and the upcoming strategic decisions.
“Karsten Dümmler shaped Netfonds from the very first idea into an industry leader and has sustainably defined our DNA,” says Martin Steinmeyer, CEO of Netfonds AG. “We are grateful to him for his life’s work and fully understand his decision to retire now.”
The Supervisory Board and the Management Board of Netfonds AG sincerely thank Karsten Dümmler for the consistently excellent and collaborative partnership. As a founder, he remains closely connected to the Netfonds family and will continue to provide advice.
