Welcome to the Quantopian Retro, a short series of interviews of Quantopian teammates, community members, and outside quants/experts. The goal of the series is to look back on Quantopian and reflect on what went right, what went wrong, and what we can learn from it all. This episode is with my friend and Quantopian CTO/co-founder, Jean Bredeche. Jean has many strengths, in this episode I hope you will be able to appreciate his easy candor and warmth, hear his motivations, and understand what he learned from building Quantopian. Have questions or ideas about the retro? Someone you want me to interview? Drop me a line via feedback at quantopian, or make a comment.thanks,fawcep.s.
