“Startup” has become a usual word for us. Everybody knows what it means, but this word had no official definition for a long period of time. Commonly when we talk about a startup, we often think about a young company with innovative ideas and the will to scale. At most of the cases, such companies have a few investors ready to help them to grow up. Angel investors always chase the future “unicorn” — a company with a valuation of more than $1 billion.
