The four sentence structure is a simple framework that can be used to create a concise and persuasive pitch. It consists of the following sentence starters:

1. "What if you could..." - This sentence paints a picture of what is possible through your product, service, or idea.
2. "So that..." - This sentence connects to a meaningful and relevant goal for the listener.
3. "For example..." - This sentence makes things concrete and demonstrates existing traction.
4. "And that's not all..." - This sentence demonstrates potential additional future opportunities.

By using this structure, you can effectively pitch your ideas, products, or services in a clear and persuasive manner.
