An elevator pitch is a brief summary used to introduce an idea or business to potential investors. It should be 30 seconds or around 100-150 words. The goal is to hook the investor and get them interested in learning more. A good elevator pitch introduces the problem being solved, describes the solution and its benefits, and makes a call to action such as requesting a meeting. It is important to practice elevator pitches to ensure they are concise, clear, and leave the listener wanting more information.
