Estonia's most remarkable innovation is the government's pioneering e-Residency programme, launched in 2014, which provides a transnational digital identity to anyone in the world.
To become an e-Resident, all you need to do is apply online and have a short interview at the Estonian embassy. Being an e-Resident isn't the same as citizenship, although the government is currently looking at revising their visa stipulations, but it allows e-Estonians to take advantage of the country's fully digitised infrastructure.
Since the programme's 2014 launch, Estonia has gained 15,000 e-Residents from 135 different countries. The goal is to have 10 million digital residents by 2025.
Another of Estonia's most remarkable technology success stories is Skype, the communications platform that has helped make the world a whole lot smaller. Three of the original development team come from Estonia. Microsoft bought Skype in 2011 for $8.5bn and its unprecedented success has helped galvanise the country's fertile, innovative business scene.
According to Mari Vavulski, who heads up the government-run initiative Startup Estonia, there are currently more than 400 start-ups operating in Estonia, and more than 40 companies founded by ex-Skype employees.
Innovators in Estonia are famously co-operative, which Mari believes is another reason for the market's vitality. In fact, such is their predilection for looking out for each other that the country's start-ups have been nicknamed the Estonian Mafia.
