Put AI to work.
Keep your data in‑house.
RAYWARD Inc. builds on-premise AI servers designed to keep your data inside your organization, and develops AI applications tailored to the way you work.
Who We Are
Generative AI can transform everyday work, from summarizing and searching documents to drafting records. Yet organizations that handle information they cannot entrust to external cloud services, such as customer data, design documents and medical records, often find it hard to benefit.
RAYWARD makes it possible to use AI and protect information at the same time, through "on-premise AI" that runs inside your own environment. We stay with you beyond installation until AI becomes part of your daily operations.

- RAYA force that is unseen, yet truly at work

What We Do
From hardware and software to ongoing operation, we take care of every step required for on-premise AI.
On-Premise AI Servers
We build dedicated generative AI servers installed at your site. The system is designed so that information is not sent to an external cloud, even when AI refers to your internal documents and data. We propose a configuration sized to your number of users and the data you handle.
- Hardware design and procurement based on your requirements
- Installation and configuration of generative AI (large language models)
- AI that answers questions based on your internal documents
- Maintenance and regular AI model updates
AI Development
After learning about your workflows and challenges, we develop AI applications that fit into everyday work, turning use cases that general-purpose chat tools cannot reach into working tools.
- Requirements interviews and AI use-case proposals
- Development of business-specific AI applications
- Integration with existing systems
- Training and support for internal rollout

The Role of On-Premise AI
As AI spreads across society, we believe that having an option to use AI while keeping information at hand matters beyond the convenience of any single company.
Enabling AI in fields that require confidentiality
Healthcare, legal and accounting practices, and manufacturing design departments have been slow to adopt AI due to confidentiality obligations and contractual constraints. We help them benefit from productivity gains as well.
Keeping business data in-country and in-house
Many cloud AI services are provided by overseas companies. The ability to use AI while keeping business data within Japan and within the organization is also meaningful from an economic security perspective.
Making the choice of approach possible
The question is not whether cloud or on-premise is better, but whether each organization can choose the approach that suits its confidentiality requirements. We aim to make that choice a practical one.
We welcome requests for information exchange and interviews from government agencies, industry associations and research institutions.
Get in touchCloud AI and On-Premise AI
Neither is better in every case; the right approach depends on the nature of the information you handle. For work involving information that cannot leave your organization, on-premise AI is a viable option.
| Item | Cloud AI | On-Premise AI |
|---|---|---|
| Where data is processed | Service provider's servers | A server installed at your site |
| Data sent outside | Input is sent to an external service | Designed to stay inside your organization |
| Cost structure | Monthly or usage-based fees | Installation and maintenance fees |
| Customization | Within the scope of the service | Configured and tuned to your work |
| Best suited for | Researching public information, general writing | Customer data, confidential documents, medical records |
* Data handling by cloud AI services varies by service and contract.

Frequently Asked Questions
What is on-premise AI?
It is an approach in which the server that runs AI is installed at your site and AI is used within your internal network. You can use AI to summarize and search documents or draft records without sending information to online AI services.
Is it true that no information leaves our organization?
We design the system so that AI processing is completed within the server installed at your site. How maintenance is carried out after installation (on-site or remote, scope of access, etc.) is agreed in advance in line with your security policy.
How much does it cost?
The required configuration varies greatly depending on the number of users, the volume of data and the response speed you need, so we do not have fixed pricing. We provide a quotation after understanding your requirements.
How long does implementation take?
It depends on hardware availability and the scope of development. We present a specific schedule together with our proposal after the interview.
Can small organizations consult with you?
Yes. We consider a configuration that fits the size of your organization and how you plan to use AI.
Do we need in-house AI or IT experts?
We provide training and support for internal rollout. The screens used day to day are designed to be usable without specialist knowledge.
Can it integrate with our existing systems?
Whether and how integration is possible depends on the specifications of your systems. We review your current environment during the interview and propose an approach.
Do you provide support after installation?
Yes. In addition to monitoring and troubleshooting, we update AI models regularly. Because AI has no knowledge of information after its training, continuous updates help maintain quality.
Can we sign a non-disclosure agreement (NDA)?
Yes. We can sign an NDA before discussing your specific work or data.
Do you work with organizations outside Japan?
We are based in Tokyo, Japan. Please contact us to discuss your location and requirements.
