This project targets social entrepreneurs—start-ups that tackle social challenges—and pursues two goals: ①build a clear support system that helps start-ups expand overseas, and ②create a nationwide mechanism that keeps uncovering promising local start-ups. WE AT will partner with overseas support groups, investors, and major companies to set up a global support line offering business meetings, investor pitches, and PoC projects. Know-how from this line will be distilled into a concise playbook future start-ups can use. Simultaneously, WE AT will run global-expansion events in key Japanese hub cities, discover high-potential social-impact start-ups, and funnel them into the support line. By continuously cycling through discovery ⇆ ecosystem building ⇆ individual support ⇆ overseas launch, WE AT will help social founders grow worldwide, broaden Japan’s start-up base, and ultimately produce Tokyo-born unicorns that succeed on the global stage.
