# Companies with a mobile app headquartered in Zagreb

Tamtam tracks 26 companies with a mobile app headquartered in Zagreb. This list ranks all of them by number of employees on LinkedIn, led by INA Grupa, HRT and Privredna banka Zagreb d. d.. Their median headcount is 592. Half of them were founded in 1996 or later.

These Zagreb-based companies with mobile apps are primarily large firms in established sectors. The list features major players in finance, retail, and telecommunications. For instance, INA Grupa operates in oil and gas, HRT is a national public media institution, Privredna banka Zagreb d. d. is a leading financial institution, and Konzum is a prominent retail chain. Croatia osiguranje d.d. provides insurance, while A1 Hrvatska d.o.o. offers digital solutions in telecommunications.

A notable pattern among these companies is their long-standing presence. Many were founded decades ago, with HRT established in 1926, Konzum in 1957, and INA Grupa in 1964. This indicates a prevalence of mature enterprises, rather than a concentration of recent startups, among the largest companies with mobile apps in Zagreb.

## How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
