What is an Ally and why do I need one?
An Ally is an advisor with experience in the area you're looking to address. Often they are academic advisors, mentors, or family friends in an appropriate industry who can share helpful insights on the project or who give very sound advice.
Allies are important because every strong entrepreneur and leader needs great mentors and advisors. Their specific knowledge, their experience, their access and support will be helpful to the project. They also show Resolution that you have been able to convince more senior individuals of the merits of your project—something you will have to do often as you build your social venture.
