Creating an elevator pitch is critical because you are always going to be out in the market telling people about your business. You will need very short versions that are about 30 seconds, up to 10 minutes or more. Your pitch should be flexible and well-rehearsed but should never sound rehearsed. It should be natural, exciting, and compelling. The goal of the pitch is not to get a full customer right there but to get them to want more information or take a meeting with you. A good pitch is about telling your story but making it meaningful to the audience. Sometimes you'll have slides to go with and other times it will be just you. Spend about an hour on Youtube watching examples and you'll have a sense of where to go. You'll find strong examples and then ones that are less so. Studying Ted Talks and other public speakers is a good way to get your structure down. Most of all. PRACTICE! Practice often, with others, solo and even record yourself. You learn to swim by doing it. Same with being good at pitching.
