Tracy Sun: Poshmark Co-Founder

Tracy Sun may be at the helm of the impressive fashion-tech startup Poshmark, but she doesn't consider herself a "fashion person." She studied biology and psychology in college with the intention of pursuing a career in neuroscience. Little did she know that she would trade medical school for business school and leave behind New York City for the tech mecca that is Silicon Valley. Sun explains how she made the transition from science to startup in episode 12 of Second Life.
