A startup or start-up is a company or project undertaken by an entrepreneur to seek, develop, and validate a scalable business model.[1][2] While entrepreneurship includes all new businesses including self-employment and businesses that do not intend to go public, startups are new businesses that intend to grow large beyond the solo-founder.[3] During the beginning, startups face high uncertainty[4] and have high rates of failure, but a minority of them do go on to become successful and influential, such as unicorns.[5]
