Activities

I write about technology in finance and real estate, and since January 2026 I have been an Editor at Business Punk. This page lists what I publish and teach, who interviewed me, the committees and boards I belong to, and the due diligence and contract work that ran next to my jobs.

Lecturer at Claude Hacker House since June 2026

Claude Hacker House is a workshop series in Frankfurt on practical work with the AI assistant Claude. I teach there together with Fayssal El Mofatiche and Christian Schulze. My sessions cover prompting, AI-assisted workflows, MCP servers and virtual organizations.

Editor at Business Punk since January 2026

Business Punk is a business magazine and digital brand in the German-speaking countries. I have been an editor there since January 1, 2026, and throughout 2026 I cover digital assets, blockchains and crypto investing.

Since March 2026 the magazine has published an investment special four times a year, Anlage Punk, as a section of the issue and as a standalone magazine in Germany, Austria and Switzerland. I write there regularly about what becomes relevant in banks, asset management, markets and infrastructure providers. The release party was on April 2, 2026 in Berlin.

Articles and a book

For several years I have published articles in Der Bank Blog and in IHK-Magazin, both in German. Other articles of mine appeared in specialist media on real estate, finance and insurance, and I write guest posts for blogs. In 2004 I wrote Skyline Guide, a pocket book on real estate projects in Germany.

2017 to January 2024: Founder and Editor in Chief of SKYLINE ATLAS

SKYLINE ATLAS is an information portal on construction projects. I started it in 2017 and was its editor in chief until January 2024. I wrote articles on real estate developments, data centers and the housing market. By 2024 the portal reached more than one million readers a year.

Interviews in the Media

Four German media have interviewed me on real estate topics: the daily newspaper Frankfurter Allgemeine Zeitung (FAZ), the public TV broadcaster ZDF, the monthly business magazine Manager Magazin and the business daily Handelsblatt. The interviews were about my two information projects on real estate. From 2004 to 2010 I built a global real estate database. From 2017 to January 2024 I was editor in chief of the portal SKYLINE ATLAS.

Co-founder of the professional network Finance Loop since January 2025

Finance Loop is a professional network for emerging technologies in finance. It grew out of an event series on blockchain and decentralized finance that I started in 2022 with three colleagues from Frankfurt. Today Finance Loop has more than 4,000 members.

Product Advisory Committee of the Digital Token Identifier Foundation

In May 2024 I joined the Product Advisory Committee of the Digital Token Identifier Foundation as an expert member. The foundation is the registration authority for ISO 24165, the ISO standard for digital token identifiers.

The committee gives the foundation recommendations on the implementation of the standard and arbitrates disputes about the issuance of identifiers. It is also the forum where the industry discusses how regulatory changes affect the crypto market. My own part is the adoption of the identifiers in Germany and other countries, through my network.

Advisory boards and memberships

I sit on the advisory boards of several organizations in web technology, in Europe and in the United States, where I advise their management. I am a member of the Digital Euro Association, a think tank on central bank digital currencies, stablecoins and crypto assets. I organize meetups on digital assets.

Due diligences, contracts and teams

Over ten years I took part in several due diligences, on the buyer’s side and on the seller’s side. My part was to examine and prepare the documents that describe the quality of the IT systems, the state of the teams and the health of the products.

Over more than 15 years I wrote and reviewed legal documents for business development and IT: contracts, licensing agreements and terms of use. At the Frankfurt-based company Blocksize Capital this included the terms of a market-data product and the framework of a partner program. I have also documented and implemented data protection measures under the GDPR.

I have more than ten years of leadership experience, with teams of up to 50 employees.
