We want to further energize Japan. This country is brimming with untapped potential. Cutting-edge technology created through the relentless efforts of researchers, entrepreneurs with high aspirations, a nation that is resilient and excels in teamwork, and a high level of customer-centric service. Our mission is to make this wonderful Japan world class again.
To achieve this, it is crucial to create an environment where ambitious entrepreneurs can actively challenge themselves, leading to the birth of awe-inspiring unicorns that astonish the world.
However, when we look around, we see that many talented entrepreneurs and potentially transformative technologies lack sufficient funding. We, as early-stage investors, aim to recognize those possibilities sooner than anyone else, providing ample funding without fearing risks, even in situations where no one else might see the potential. By properly allocating funds where they truly belong, we hope to foster innovations that can greatly impact the world.
While funding is crucial in nurturing a business, it is often not enough to ensure great success. Even with sufficient funding, it is not always possible to achieve great success. Drawing from our experience of growing numerous companies, we will share our insights with entrepreneurs and walk alongside them, helping them realize their full potentials. As an “advocate of entrepreneurs” with a commitment to hands-on support, we plan to create world-renowned mega-ventures.
When entrepreneurs generate a multitude of success stories and share their achievements with others, a spiral of challenges and successes is set in motion. Anyone from any generation will be able to challenge themselves. We hope to make Japan a country overflowing with such proactive energy.
Angel Bridge will serve as a bridge to great success for aspiring entrepreneurs.
