The hype is only just starting in the region, and it’s in large proportion due to a handful of companies that have proven the emerging ecosystem’s value proposition as a lean value creator, rich with tech talent. Today, we take you through a list of Southeast Europe scaleups that were most successful in expanding to some of the largest markets in Europe and the US.

As minimum criteria, we decided to select startups and scaleups that have not yet made an exit, have no more than 15 years in the market, and are either based in or have offices in Southeast Europe. The list that follows is in alphabetical order.
