Our vision is to increase the knowledge and learning capability of early-stage startups to build innovative products and services by empowering them with GenAI technologies. We are putting together an interactive handbook to guide the startups to leverage various GenAI technologies, and a GenAI toolkit that can assist the activities of early-stage startups, including ideation, problem-customer-solution validate, and MVP development. In this flashlight event, we will present the first pieces of the puzzle: the conducted and ongoing studies that contribute to the realization of the vision.
