Bulgaria is not only about history and yogurt. Sofia has become one of Europe’s tech hubs, and some Bulgarian companies now serve customers around the world. Here are three success stories.

Chaos and V-Ray: Bulgarian software honoured by the Academy Awards

Chaos was founded in Sofia in 1997 by Peter Mitev and Vladimir Koylazov. Its rendering software V-Ray turns 3D models into photorealistic images and is used by architects, designers and film studios. In 2017 Koylazov received a Scientific and Engineering Award from the Academy of Motion Picture Arts and Sciences for creating V-Ray, and in 2021 the software won an Engineering Emmy. V-Ray has helped create visual effects for many Hollywood films.

Telerik: the company that inspired a generation

Telerik was founded in Sofia in 2002 and built software tools used by developers around the world. In 2014 it was bought by the US company Progress Software for $262.5 million, one of the biggest tech deals in Bulgarian history. Its founders went on to invest in new startups, and the free Telerik Academy has trained thousands of young programmers.
