As the CEE region continues to establish itself as a key player in the global tech landscape, 2023 saw an influx of investment that has been pushing the development of regional startups and companies.

Despite these obstacles, there were, however, notable exceptions as some outliers successfully secured substantial investment rounds to fuel their growth initiatives.
