Why Japan, Why Now
The data is unambiguous. Japan is the highest-return untapped SaaS market on the planet.

Internal financial modelThe gap is the opportunity.
Japan's enterprise generative AI adoption rate stands at only 27% — significantly below the United States (68.8%) and China (81.2%). Yet 46% of Japanese firms report they are "currently evaluating adoption." For overseas AI startups, this represents an open window with minimal competition.
The obstacle is not market appetite — it's execution capability. Japanese is one of the most challenging languages for LLMs, and no product succeeds in Japan without native-level UI/UX, customer support, and sales localization. That's exactly what we provide.

How Bybeit Started
Bybeit was founded by two Keio University students — CEO Hinata Yamasaki and CTO Haruhiro Matsumoto — who won the Grand Prize at the NIKKEI Future Society Co-Creation Business Competition and went on to lecture at the 2025 Osaka Expo Theme Week.
Starting as a job market platform, they shipped two apps to the App Store, then pivoted after recognizing a far larger opportunity: the structural gap between overseas software companies desperate to enter Japan, and the scarcity of English-proficient Japanese professionals capable of bridging that gap through execution — not just translation.
The insight is simple: the very talent pool that can execute Japan GTM at the highest level — kikokushijo students at elite universities with native-level English — are also the people who most need real-world business experience. Bybeit turns that alignment into a company.
