Taxfix Appoints Markus Berger-de León as Chief Operating Officer to Drive UK and European Growth

London, UK, 6 November 2025: Taxfix, Europe’s leading AI platform for digital tax management, has announced the appointment of Markus Berger-de León as Chief Operating Officer (COO). Markus succeeds Dr. Daniel Kreter, who is stepping down after seven successful years to embark on his own entrepreneurial journey.

This appointment comes as Taxfix focuses on profitable expansion across Europe and the UK, following the successful integration of London-headquartered TaxScouts earlier this year. With operations now spanning Germany, the UK and Spain, the company is focused on scaling its platform, sustainable expansion, and operational excellence to deliver a seamless, unified customer experience across markets. 

At the core of this strategy is an AI-first approach deeply embedded in the Taxfix operating system. In his new role, Berger-de León will focus on ensuring that Taxfix continues to deliver fast, secure, and personalised tax solutions for a wide range of taxpayers across Europe, from first-time filers and self-employed professionals to landlords, investors, and limited company owners. He will also oversee day-to-day operations, including customer service, tax operations, and the expansion of Taxfix’s advisory platform. 

Prior to joining Taxfix, Berger-de León held senior leadership roles at McKinsey & Company, advising global businesses on building and scaling digital business models, and served as CEO of MyHammer and StudiVZ, as well as COO and later CEO at Jamba, where he was instrumental in the company’s success.

Martin Ott, CEO of Taxfix, said: “We’re delighted to welcome Markus to the leadership team. As we continue to scale our presence across Europe and the UK, his experience in building and aligning high-performing teams will be instrumental in driving operational excellence and ensuring seamless collaboration across markets. With AI deeply embedded in our platform, Markus will also lead the charge in harmonising our technology and operations, helping us deliver a consistently outstanding experience for our customers and partners. I also want to thank Daniel for his trusted collaboration and for his major contribution to Taxfix’s success in recent years.”

Markus Berger-de León, COO of Taxfix, said: “I’ve seen firsthand how powerful effective financial advice can be. The opportunity to bring that clarity and support to millions of people by making one of the most complex areas of finance – taxes – simpler and more accessible, was very compelling. Taxfix’s blend of technological innovation and social impact, combined with its strong AI strategy, positions us to redefine the future of tax and financial services across the UK and Europe.”
