 Comment from CEO&General Partner  Kazumasa Watanabe of aSTART Co.,Ltd.

Our company has cultivated extensive knowledge and relationships, particularly with enterprises providing low Earth orbit services for small satellites. One of the significant challenges we have identified is the absence of propulsion systems that can deliver safety, high-performance, low-cost, sustainability, and short-lead-times. Pale Blue is developing technologies that address all these issues simultaneously, revolutionizing the satellite propulsion market. We are fully committed to supporting this transformative journey that will change the world.

In recent years, the space business has been experiencing significant global growth, and it remains one of the few promising sectors where Japanese startups can compete on an international level. Pale Blue, a highly capable startup originating from the University of Tokyo, has already built a strong track record of orders from both domestic and international clients. We have decided to invest in this promising company and are committed to fully supporting their business expansion as ITV.
