A private equity buyer is a financial buyer that acquires a company to grow it and sell it again, either as a platform to build on or as an add-on to a company it already owns.
In a sale
Because it plans to sell the business again, and a founder who keeps a stake and stays involved shares in that next sale: the rolled equity is paid out when the buyer sells, the second bite. A private equity platform discounts owner dependency heavily, because a platform that depends on one person cannot be built on. An add-on buyer pays for what fills a gap in the platform it already owns.
