In this episode of Careers in Discovery, we’re joined by Jelena Aleksic, a serial entrepreneur, business coach, and director at SparkBio. Jelena shares her fascinating journey from genetics researcher to founder and start-up builder, including the lessons she learned from creating seven businesses across life sciences, tech, and even live entertainment. She opens up about her transition from academia to entrepreneurship, the importance of testing ideas early with customers, and why stepping away from a company can sometimes be the right choice. We also talk about embracing curiosity, building businesses that align with your passions and strengths, and how finding the right personal fit is key to both success and happiness.
