A startup starts from an idea that can revolutionize the world and as it continues its growth it goes through many funding stages and end up with an IPO (Initial Public Opening).
An initial public offering, or IPO, is the first sale of stock by a company to the public. A company can raise money by issuing either debt or equity. If the company has never issued equity to the public, it’s known as an IPO.
Going public raises cash, and usually a lot of it. Being publicly traded also opens many financial doors for the company.
