Start-up, Scale-up, Business Angel, Unicorn, Venture capital – What do all these terms describe? Let’s have a guess… maybe “start-up” or “scale-up” is a kind of a call to action? No, it is not. “Business angel” and “unicorn”, maybe these are two creatures one can find in a fantasy novel? No, they are not. So, what does these terms refer to? We all have heard at least one or two of these terms already because we encounter them almost every day when scrolling through news websites, newspapers and the business press. They are used in articles about young, innovative and ambitious companies in the IT industry. We tend to use these terms in a way which suggests that we are absolutely familiar with their meaning. But on can imagine that in truth it is not clear for everybody what for example “scale-up” describes. That is why in the following lines I will spend some time to explain what a start-up is, what scale-up requirements are and where one can find business angels, unicorns and venture capital.
