This document summarizes an analysis of founding CEO versus professional CEO performance in the software as a service industry. It analyzes data from 48 SaaS companies that had exits from 1998-2009, comparing metrics like total investment, time to exit, and exit valuation between companies led by founding CEOs versus those led by professional CEOs hired later. It finds that companies led by founding CEOs generally had better performance on these metrics, even when accounting for biases.
