These visualizations illustrate how ownership of a venture-backed company evolves as funding is raised. One scenario imagines changes to ownership in a well-performing startup, and the other is loosely based on a careful analysis of Zipcar,* a ride-sharing company that experienced substantial dilution before eventually going public and being acquired. These diagrams simplify complexities such as the ones discussed in that analysis, but they give a sense of how ownership can be diluted.
Understanding the value of stock and equity in a startup requires a grasp of the stages of growth a startup goes through. These stages are largely reflected in how much funding has been raised—how much ownership, in the form of shares, has been sold for capital.
