Background of the Event
Plex's mission is to "create mechanisms that move Japan." The company operates businesses such as human resources, SaaS, and M&A brokerage, primarily in essential worker industries and other core Japanese industries. In 8 years since its founding, Plex has created over 20 businesses, growing its sales to 9.6 billion yen. Currently, it is an organization of 700 people, continuously generating multiple new businesses. At Plex, it is common for new graduates to launch new businesses as business leaders, providing opportunities to be involved in business creation from a young age.

Behind this business creation is a series of processes: deciphering market structures, identifying customer issues, and implementing strategies. This internship provides participants with opportunities to think, discuss, and execute based on the business creation processes that Plex has actually undertaken. It aims to be a practical learning environment for students who aspire to challenge business development and management in the future.

Comment from Representative Director Shun Kurosaki
Plex has created businesses by deciphering market structures, identifying issues, and executing them thoroughly. Over 20 businesses have been launched in 8 years since its founding, and many of them have been created primarily by young teams, including new graduates.

We believe that business creation is not a special talent but something that can be acquired through repeated correct thinking and execution. In this internship, we want participants to experience that process in the most realistic way possible. We hope it will be a challenging and interesting opportunity for students interested in structurally understanding markets and industries and creating new value.

Plex also looks forward to meeting talent who will lead future businesses through this internship.
