The stories we hear in the field are what inspire our technology – and our technology is driving a digital supply-chain revolution on the ground.

PemPem was born out of years of in-depth fieldwork in informal supply chains in multiple geographies. Over and over we witnessed technologies perform well in the lab, and then fail when put into practice in remote areas. With one foot firmly rooted in fieldwork and the other in our technical expertise, we knew we had the power to create a better solution, for the benefit of farmers, consumers, and the planet.

At the time, Joann was a PhD student at Stanford University specializing in operations management and earth systems analysis. She would go on to be an Assistant Professor at the MIT Sloan School of Management before devoting herself full-time to PemPem in 2022.
