14 CEE tech startups aspiring to revolutionize life and business on a global scale

tech startups

If we ask you to name a few companies that have transformed the way we communicate, work, study, shop, and have fun, you’ll almost certainly point to Microsoft, Google, Apple, Amazon, and Facebook, among other US technological leaders.


However, not all innovators with the guts to turn their ideas into a reality start out of a garage or a university dorm room somewhere on the other side of the Atlantic.


One region that has in recent years established itself as an incubator of startups and an attractive destination for venture capital is Central and Eastern Europe (CEE). The Estonian messenger application company Skype, the Czech cybersecurity software provider Avast, and the Bulgarian software company Telerik, whose co-founders also built Campus X, are just a few examples of successful exits from the region.


Below we present 14 CEE tech startups that have already stood out with their value proposition and market fit, achieved some success and demonstrated significant potential for growth beyond the region.


Note: The companies on our list are either based in CEE or have a strong connection to the region – e.g., their founders come from a CEE country, they have attracted funding from local investors, and/or a substantial number of their staff are based in the region. Since we’re based in Sofia, we’ve given Bulgarian startups a bit of a preferential treatment but we’re only human, after all.

The right environment for tech startups


What are the main factors that have contributed to the success of the tech startups presented in this article and continue to enhance their growth potential?


Offering a high-quality product or service that addresses specific pain points of specific groups is a must, but it isn’t enough. Having a team of versatile professionals led by a visionary leader helps a lot, but it isn’t enough, either. Having access to investors, mentors, and a solid base of potential customers increases a tech startup’s chances of success, but it doesn’t matter much if the company doesn’t have a top-notch product/service and the right team.


To thrive in the competitive international environment in the 21st century, tech startups need to be part of a vibrant ecosystem that gives them access to state-of-the-art infrastructure, top talent, abundant capital, and a support network facilitating the exchange of knowledge and experience.


Campus X is precisely such an ecosystem in Sofia, Bulgaria. Among our current members are Telerik Academy,, Digital Lights, Storytel Bulgaria, and Eleven.
