About a year ago, I took on the best imaginary job out there: CEO of CryoThaw, the finest company that never existed. I had come across a tweet announcing the 2017 Young Entrepreneurs Scheme competition, sponsored by the University of Nottingham with partners from the U.K. government and industry, in which teams form hypothetical startups based on feasible scientific ideas. As a graduate student unsure of my career plans, I was excited to explore outside academia. I also saw it as a way to develop my leadership skills. So, with the support of my supervisors and funders, I decided to give it a go. I recruited three other students, and we chose to focus on improving organ transplantation. I thought I had everything under control. I couldn't have been more wrong.
