Gio Colella, co-founder of RelayHealth and Castlight Health, speaks with Bryan Roberts at Venrock about starting companies and the importance of surrounding yourself with amazing people. Colella advises other entrepreneurs to find partners you can trust, who are very different from you, and who are aligned with the vision for the company. Colella and Roberts also talk about the early days of Castlight and the iterative process that revealed the foundation of the company, as well as the challenges related to managing through the highs and lows as a public company. They also talk about what made RelayHealth’s acquisition by McKesson so successful, in a world where M&A horror stories are rampant. Colella immigrated to the US from Italy and left his psychiatry practice to answer the call of entrepreneurship.
