One of the challenges of the startup ecosystem in Japan is the lack of M&A awareness and experience, and the fact that exit strategies are heavily weighted toward IPOs, which can easily lead to stagnant growth, small IPOs, and second financing deadlocks after growth listings. This project aims to fill a missing piece in Tokyo’s startup ecosystem by providing a positive atmosphere for startups with the aforementioned challenges to have M&A as an option for their next growth and exit, fostering a positive atmosphere for choosing M&A, sharing know-how and knowledge, and so on. We will fill in the missing pieces of Tokyo’s startup ecosystem. By doing so, we will accelerate the flow of funds into the startup ecosystem, support and human resources (an increase in the number of people with M&A knowledge, serial entrepreneurs and angel investors), and the circulation of knowledge, thereby increasing the potential for expanding the base and creating unicorns, and making a sustainable contribution to the 10x10x10 goal of the Tokyo Metropolitan Government. We will contribute to the Tokyo Metropolitan Government’s 10x10x10 goals.
