The article by Sarah Tavel introduces the concept of the "Hierarchy of Marketplaces," which is a framework for understanding the evolution and success of online marketplaces. It starts by discussing the challenges marketplaces face, such as the chicken-and-egg problem of needing buyers and sellers simultaneously.

This stage is crucial for survival, as it establishes the foundation for further growth and development in competitive environments.
