This type of pitch is called an elevator pitch because it should be concise and informative enough to let someone know who you are, what your business does, and why they should be interested -- all in the time it takes to ride an elevator.  First, consider the problem or need that your venture addresses. This is often effectively stated as a question, which is why TV advertisements often begin with questions such as “Did you know that….” or “Are you tired of…” or “Have you ever had a problem doing…”. Second, consider how your product or service fixes the issue you’ve identified. This should be no more than 1 or 2 sentences, but should be as specific as possible without getting into jargon. Third, describe the main benefit of your product or service. This could be a description of how it achieves something for the customer, or how it outperforms your competition. Finally, consider what you need from investors to get your venture going. This part can be longer, because it needs to express your basic needs, your experience and credentials, and why your investors can trust you to succeed. Keep your elevator pitch short! Many experts suggest that it should not be longer than one minute. Remember: attention spans are short. Hook your audience quickly, or you may not hook them at all. This should summarize all the information in your business plan. You should be able to deliver it, without rushing, in about 15 minutes. You will likely be jittery about pitching your business at first, so get in some practice. You can rehearse delivering your elevator pitch and discussing your business plan with friends, coworkers, and other colleagues. You will probably make mistakes at first. Ask the people you practice with for honest feedback. Were you expressing your ideas clearly? Did you sound nervous? Did you talk too quickly or too slowly? Where do you need to explain more, and are there explanations you could cut?
