A pitchbook is a sales book used by investment banks to sell products and services, as well as to pitch potential clients. The purpose of a pitchbook is to secure a deal with the potential clients. It provides an overview of the firm, including historical information, financial strength, and services available to potential clients. In investment banking, pitch books refer to sales presentations that a bank uses to persuade a client or potential client to take action and pay for the bank’s services. Pitch books typically contain sections on the merits of the transaction; analysis of potential buyers or sellers; pricing and valuation information; as well as key risks to mitigate.
