The term startup refers to a company in the first stages of operations. Startups are founded by one or more entrepreneurs who want to develop a product or service for which they believe there is demand. These companies generally start with high costs and limited revenue, which is why they look for capital from a variety of sources such as angel investors, venture capital funds, etc.
The investments into the startups are to develop and validate a scalable economic model, based on which lays the product/service provided by the company.
