This document provides a 4-step process for deciding whether a start-up should be structured as a non-profit or for-profit organization. Step 1 considers the goals of making money or giving away services/money. Step 2 evaluates the viability of a for-profit business model. Step 3 examines potential capital sources that may require a non-profit or for-profit structure. Step 4 discusses the importance of founder control versus board/investor control in deciding between non-profit and for-profit structures. The document recommends evaluating hybrid structures if neither structure fully meets the founder's goals.
