A management buy-in (MBI) occurs when a manager or a management team from outside the company raises the necessary finance, buys it, and becomes the company's new management.[1] A management buy-in team often competes with other purchasers in the search for a suitable business. Usually, the team will be led by a manager with significant experience at managing director level.
The difference to a management buy-out is in the position of the purchaser: in the case of a buy-out, they are already working for the company. In the case of a buy-in, however, the manager or management team is from another source.
