During the past few years, Europe has quickly established itself as the “fastest growing region for VC investment”, with Southeast Europe hitting the spotlight by attracting bigger ticket sizes and funding rounds for the startups in the ecosystem. In 2022 only, the region has already produced three unicorn companies – thus, growing the total number to six. This signals an underlying structural trend showcasing an ever-expanding waterfront of opportunity for technology companies in Southeast Europe that significantly differs from the short-term valuation fluctuations, Sequoia Capital Partner Bogomil Balkansky says.

The year of 2021 has proven to be the strongest one in the history of startup growth in Southeast Europe so far – the Recursive listed more than 210 deals of total value of over $2.55B (€2.25B). Moreover, more than 15 startups exited to international players.The number of businesses reaching later growth stages is escalating with enterprise software, martech, and fintech remaining the leading sectors. All these make the region all the more interesting for global investors.

In this article, we take a look at the top 13 international investors (divided by regions) funding the fastest growing startup companies in Southeast Europe:
