Why we do

We aim for a future filled with great UX that enables “Liberty (freedom)

Employees can choose office equipment that best fits their individual needs

▍We aim to realize an era in which people can choose the UX that feels most true to themselves, moment by moment. ▍As digital technology has become deeply embedded in everyday life, a question has emerged: “Will technology and data lead us to a utopia, or a dystopia?” In a world where digital is ubiquitous, the combined power of UX and technology is immense. It can even shape—or control—human behavior. When misused, it can deepen inequality or be exploited in harmful ways. ▍That is precisely why we believe the future created by UX and technology must be one in which people are able to choose experiences that align with who they are at each point in time. The society we should strive for is one where those who misuse UX for selfish purposes are left behind, while meaningful, empowering UX that enables self-realization flourishes—and can be freely chosen by anyone. ▍A world filled with services trusted by users, where companies that share the same vision come together to build a richer society. At beBit, we are committed to working toward such a future—one that enables a more open and liberated post-digital society.
