Over the past decade, the marketplace or talent platform model has reshaped how we live and work—from transportation, food delivery and travel through to engineering, design, consulting and now, legal.

A group of Harvard Business School professors and researchers and Boston Consulting Group consultants recently wrote about this evolution for the Harvard Business Review. “[A] new generation of talent platforms—such as Catalant, InnoCentive, Kaggle, Toptal, and Upwork—has emerged. In contrast to Uber…these platforms offer on-demand access to highly skilled workers,” they wrote.
