Corporate accelerators have developed as an important mechanism for corporate entrepreneurship and digital innovation across industries worldwide. Corporate accelerators are typically time-limited programs that provide mentoring and educational support to a selected group of start-ups acting as intermediary between corporate parents and participating start-ups.

We discuss their objectives, design, and how these programs create value providing relevant insights for both academics and practitioners.
