Software Development & Web Design in Luxembourg
Software development, web design and hosting for Luxembourg's funds, banks, EU-institution suppliers and professional-services firms, delivered remotely from Bucharest.
Luxembourg City, with about 138,000 people, is a financial centre built on investment funds and banking, with EU institutions on the Kirchberg plateau and law, audit and consultancy firms around the Gare district. Belval and the University of Luxembourg add research. Firms here work in French, German, English and Luxembourgish, often in one document.
What a business in Luxembourg has to get right
Luxembourg's data-protection authority is the CNPD. Financial entities have been subject to the EU's DORA resilience rules since January 2025, and NIS2 duties reach more sectors. Suppliers to public bodies must send structured e-invoices, and sites need legal notices (mentions légales) and cookie consent.
How we work with Luxembourg
GRADAX works from one office in Bucharest and delivers to Luxembourg remotely, in a time zone one hour ahead of yours. Meetings happen by video, and sites can be written in French, German and English. Hosting runs in EU datacentres in Germany and Finland.
