1. Stockholm, Sweden. Did you know that Stockholm, the capital city of Sweden, was ranked the second most prolific tech hub in the world right after Silicon Valley? According to Bloomberg, it’s the second most innovative city in the world.

2. Kiev, Ukraine. There is a reason why outsourcing is one of the most mature sectors of the IT industry in Ukraine — there are about 166,000 IT specialists and the Ukrainian IT industry is expected to reach $10 billion in value by 2020.

3. Tallinn, Estonia. Estonia is a hotbed for startups — apparently it only takes about five minutes to register a new company there. This small country, with population of only 1.3 million, holds third place regarding the highest number of startups per capita.

4. Valletta, Malta. In recent years the Maltese government has proved to be forward thinking. New laws and blockchain-friendly regulations introduced last year, created a haven for Crypto companies to grow and develop in Malta. Many of the top crypto exchanges have already relocated to this sunny island.
