Paul Lightfoot is a serial entrepreneur who has learned several lessons the hard way, from raising money to communicating purpose to hiring (and firing). After spending much of his career as a software CEO, Paul wanted to follow his “calling” to enter the world of sustainability and foodtech.

But this meant moving from a familiar career trajectory to an industry that, 10 years ago when Paul was entering it, barely even existed. In 2011, Paul founded BrightFarms, which uses hydroponic greenhouses to produce locally sourced packaged salads in the US. Along the way, he has made several critical decisions for his startup’s success, including voluntarily stepping back from the role of CEO.
