A startup is a venture that is initiated by its founders around an idea or a problem with a potential for significant business opportunity and impact. Often the actual development starts even before that with a search of an idea or a meaningful problem worth solving and building a committed founding team aligned with shared vision to make that vision into reality.
Most of the startups focus on quick and sustainable scalability, which essentially includes standardization of processes, which were previous unstructured and can be replicated by the company in quick time.
