Abstract: An automated system utilizes a networked computer system such as the Internet for initiating and managing mergers and acquisitions of businesses between third parties. A host computer system connected to the network hosts a site operated on behalf of an investment banking firm. The site includes a secured login area, a seller registration area, a buyer registration area, a unique home page area for each registered seller and registered buyer, and a secure administration area. In each registration area a user enters profile information and is registered as a registered seller or registered buyer. The registered seller also provides detailed confidential information about a business to be offered for sale in addition to the seller profile. The unique home page area displays information and communications relating to opportunities matching the profile for that registered seller or buyer.
