OSUSHI Inc. (Headquarters: Shibuya-ku, Tokyo; CEO: Ryo Tamoto), a professional team specializing in AI development, is accelerating corporate decision-making for new business ventures and DX promotion through its rapid prototyping development business.
Product leads who have driven business growth exceeding 1 billion JPY in ARR and PMs with experience in large-scale system implementations are leading the design. By combining this with the latest AI-driven development, we can produce a "working demo" in as little as 3 days, which traditionally takes several months, shortening the corporate consensus-building process from months to weeks.
Development Projects Hampered by the Verification Dilemma
Currently, the speed of decision-making is the biggest bottleneck for DX and new business initiatives in Japanese companies. A recent survey reveals that 95.5% of major corporations feel "anxiety about the validity of their self-proposed plans," with the primary cause being "insufficient validation during the planning stage (61.9%)" (※1).
On the other hand, traditional contract development processes suffer from the deep-rooted problem of "prototyping taking too long (38.5%)" (※2). This creates a dilemma where companies want to validate but cannot form a tangible product in time, leading to stalled projects. In 2026, with rapidly changing market environments, it is essential to move beyond "uncertain consensus-building" relying on words and static documents, and adopt methods for speedy, high-quality verification.

Strengths of OSUSHI's Rapid Prototyping Development
1. **Design Led by PMs Who Know How to "Win"**
Experienced professionals with a track record of scaling businesses to over 1 billion JPY in ARR, experience in large system implementations, and PM roles at startups lead the design. They understand the critical points of business models and implement solutions by working backward from "what needs to be demonstrated to prove return on investment."
2. **Short Delivery Times & Cost-Performance through AI-Driven Development**
By integrating the latest generative AI into the development process, coding man-hours are drastically reduced. We achieve an astonishingly short delivery time of as little as 3 days, while also offering services at approximately 1/3 the cost compared to other companies.
What is AI-Driven Development?
AI-driven development is a development methodology where AI assists or automates code generation, testing, debugging, and documentation. At OSUSHI, we incorporate AI agents throughout the entire development process to maximize development efficiency, allowing humans to focus on more creative and strategic tasks.
Through this rapid prototyping development business, OSUSHI will strongly support companies' DX promotion and new business creation.
