Initial public offerings (IPOs) allow privately-owned companies to sell shares to the public and become publicly traded. The process involves hiring lawyers and investment banks, drafting prospectuses detailing the company's history and finances, setting the IPO price, and conducting roadshows to drum up interest from investors. While IPOs provide funding and prestige, they also bring increased regulatory requirements and less control for founders. The decision to go public involves weighing these advantages and disadvantages.
