Entrepreneurs-in-Residence (EIRs) have deep operational experience and have gone through the process of turning new technologies to new businesses. These experts act as an early “sounding board” for Yale innovators contemplating a new startup. In a logical, stepwise fashion, EIRs help frame both the risks and the benefits of starting a new company, asking relevant questions about everything from the science, to the business, to the market and helping faculty chart a successful path forward. Each EIR has decades of practical private-sector experience in building their own companies and valuable connections with industry and investor communities.
