Slush is probably the most important event for startups in Europe. This year alone, it was able to attract something like 13,000 people from all over the world, even though it is held in Helsinki, Finland, which is not exactly the most welcoming city in November (it is friggin’ cold). In fact, the name “Slush” comes from the fact that in this period of the year, in Helsinki, usually the streets are covered in a mix of water and snow, which the Finns call “Slush”.
