Marc Kreitz

Overview

Marc Kreitz is a Luxembourg-based entrepreneur with over twenty years of experience in real estate and digital technology. He is the founder and manager of several specialised platforms dedicated to property analysis, valuation and simulation in Luxembourg and internationally.

Alongside his property advisory activities in Luxembourg, Marc Kreitz has positioned himself on the Dubai real estate investment market, guiding Luxembourg-based investors seeking to diversify their assets towards the United Arab Emirates.

He is also involved in the development of solutions based on artificial intelligence applied to property market analysis, with the aim of digitalising and modernising sector practices in the Grand Duchy.

Activities

Real estate in Luxembourg

Marc Kreitz is active in property valuation, the sale of residential and commercial assets, and real estate project development in Luxembourg. His expertise covers market analysis, asset valuation and transaction management for private clients.

Investment in Dubai

Through DubaiProperties.lu, Marc Kreitz offers a private advisory service for real estate investment in Dubai, aimed primarily at Luxembourg-based investors. He provides personalised support bridging the Grand Duchy and the UAE — a market he considers complementary to European investment due to its regulatory framework, tax environment and international momentum.

Digital platforms and artificial intelligence

Marc Kreitz develops an ecosystem of online platforms dedicated to the Luxembourg property market, covering automated valuation, capital gains calculation, notary fees and AI-driven market analysis via Stop.lu. These tools aim to make property information more accessible and transparent for both private individuals and professionals.

His most recent project, imo.lu, is likely the most accurate property valuation tool ever developed in Luxembourg. For the first time, a formula of such complexity — combining advanced algorithms and artificial intelligence — has been applied to real estate valuation in the Grand Duchy, covering apartments, houses, land and garages across all 122 Luxembourg communes.

Beyond real estate, Marc Kreitz has also launched secondhandshop.lu, the first AI-driven second-hand marketplace in Luxembourg. The platform integrates automatic photo recognition, AI-generated multilingual listings (French, German, English), as well as algorithm-assisted categorisation and price estimation — an unprecedented approach on the Luxembourg second-hand market.
