Pre-IPO refers to the stage of a company's development when it is preparing to go public. The main benefit of pre-IPO is that it allows a company to raise capital by selling shares to institutional investors and other accredited investors. This infusion of cash can help a company to finance its growth and expansion. Pre-IPO also provides a way for a company to generate buzz and build up excitement among potential investors before its IPO. This can help to drive up the price of the stock when it goes public.
