In Dragons' Den, an entrepreneur who presents a business to the investors is called a pitcher. The word describes the person making the business pitch, rather than the product or company itself.
A typical pitch explains what the business sells, how much revenue it has generated and how much investment is being requested. The entrepreneur also states the percentage of equity offered, allowing the dragons to calculate the implied valuation. The dragons then question the pitcher about costs, competition, intellectual property and growth plans.
The term is used broadly in business and start-up culture. It does not necessarily mean that the entrepreneur has already secured investment, because the presentation is only the beginning of the negotiation. A dragon may make an offer, ask for a different share or decline to invest.
Even when a deal is agreed in the studio, it normally remains subject to further checks. As a result, an on-screen pitch and a completed investment are not always the same thing.
