On this episode of What Fuels You, Stefan Weitz discusses gut health, his diagnosis with Multiple Sclerosis and his probiotic subscription company, Jetson, that he founded as a better way to manage his chronic disease and also help “make 50 million Americans healthier.” In addition to Jetson, Stefan has an incubator called 87 that heavily invests in exciting direct to consumer companies – many of which he shares details about. Stefan also reflects on the impactful advice his first boss at Microsoft gave him, the three ways he believes you can view success and how he would rate himself on each scale, and what ultimately drove him to leaving Microsoft after nearly two decades (and why he wishes he did it sooner).
