Software Development & Web Design in Zagreb
Software development, web design and hosting for Zagreb's banks, telecoms, retail, IT and public-sector businesses, delivered remotely from Bucharest.
Zagreb, with about 767,000 people, is Croatia's capital and its largest city, home to the University of Zagreb, most major banks and telecoms, and the Zagreb Fair grounds in Novi Zagreb. Its IT and startup scene is the largest in the country. Retail, services and public bodies all compete for attention in one dense market.
What a business in Zagreb has to get right
Croatia's data authority is AZOP. Fiskalizacija 2.0 has required e-invoicing and fiscalisation between businesses since 1 January 2026, and the Cybersecurity Act implements NIS2. Sites sell in euros since 2023 and must show company details, and legal pages are expected in Croatian.
How we work with Zagreb
GRADAX works from one office in Bucharest and delivers to Zagreb remotely, in a time zone one hour ahead of yours. Meetings happen by video, and sites can be written in Croatian and English. Hosting runs in EU datacentres in Germany and Finland.
