Comarch is a Polish software company founded in Krakow in 1993 by a university professor, and it is unusual in central Europe for building and owning its own products rather than reselling or implementing other vendors' software. Its portfolio spans telecommunications operations and billing systems, banking and insurance software, enterprise resource planning, loyalty management and healthcare systems, sold to customers in more than sixty countries. Headquartered in Krakow and listed in Warsaw, it also operates its own data centres and remains substantially controlled by its founding family, which has kept it independent through decades of consolidation around it.
