Explain what the project/product/service actually is. What does it do? How does it work in very simple terms. This could be a short "elevator pitch" summary of your project so that people know exactly what project you're pitching.

Explain why this product/service is needed and provide some context for your project. Why is the problem worth solving?

Make clear who this project/service/product is aimed at. Is it for a particular geographic audience, or a particular demographic group? Or is it for people with a particular interest (i.e. a psychographic?) Or maybe it's for people who have a particular problem or a certain need. Make clear who you are building this product/service/project for so that it's clear who will benefit from it.

How will people find out about this product/service/Web site/project? Mentioning vaguely that you'll use social media to get the word out is generally not sufficient. It's important to explain how you'll raise awareness for this in a marketplace that is increasingly cluttered with all sorts of new apps/sites/products/services launching every day. What techniques/tactics/tools will you use, or how will you go about taking advantage of existing or new platforms to reach your intended audience? How will you measure progress in reaching your audience? What will success look like in reaching your audience? What are key metrics/performance indicators that you'll be assessing as your project moves forward?

How will you make ends meet? What do you expect your primary three, five or 10 costs will be? What do you expect your primary revenue streams to look like, and how long do you expect it might take for you to get to that point? Why will people pay for your service/product and how will the value proposition differ from other products/services people are paying for?
