Market overview

Croatia joined the EU in 2013 and the Eurozone in 2023, making it the most recent EU member to adopt the Euro. Zagreb is the commercial capital with finance, professional services, and technology activity. Croatia has a small but globally competitive IT sector — the Infobip platform (now a $1B+ company) was founded in Zagreb. Tourism is the dominant economic force, particularly along the Dalmatian coast.

Primary business hubs: Zagreb, Split, Rijeka, Osijek.

Outreach benchmarks & strategy

Croatian B2B cold email in English works well for the technology and internationally-oriented business sector. Croatian-language outreach is preferred for domestic companies. The relatively small business community means referrals from Croatian business networks carry high credibility.
