What is the definition of a Pitch?

Pitch is a term that refers to the attempt by a firm to convince another firm to buy or sell something.

A contextual example is "Goldman Sachs pitched several mid-cap tech companies to a private equity company".

Pitches are often speculative with the target buyer having no or little prior knowledge of the companies being pitched and as a result, many pitches end in nothing at all. A lot of the time of Analysts and Associates at investment banks is spent creating models compiling information for pitches.
