System Development
We build business systems end to end, from requirements to long-term operation, and vertical AI for any industry: LLM applications grounded in your own data and AI agents that carry out your workflows.
01
Our Service
We build the systems your business runs on, and the AI that makes them smarter: from requirements and architecture to vertical AI shaped around your industry's data and workflows.
For business systems, we cover design, development, testing, deployment and long-term operation. For AI, everything from LLM applications that answer from your own documents to agents that carry out multi-step work, deployed securely and kept accurate in production.
System development
Requirements & system design
We turn business needs into clear requirements and an architecture that can grow, with data, integrations, security and scale planned up front.
Application development
Web, business and back-office systems built end to end, from the database and APIs to the screens your people work in.
Testing & quality assurance
Unit, integration and acceptance testing at every stage, so defects are caught early and releases land on schedule.
Deployment & operations
Release, monitoring and operational support after go-live, with clear runbooks and agreed response times.
Modernisation & system replacement
Ageing systems migrated, upgraded or replaced in planned stages, without stopping the business that runs on them.
Offshore development
Our offshore team adds capacity at lower cost, managed from Japan so quality and communication stay consistent.
AI & LLM
AI use-case & data assessment
We find where AI pays off in your operations, check that your data is ready, and agree accuracy targets before anything is built.
LLM applications grounded in your data
Assistants that answer from your own documents, manuals and records using retrieval (RAG), and show the source behind every answer.
AI agents for business workflows
Agents that carry out multi-step work such as document checks, data entry and report drafting, with a person approving the decisions that matter.
Model selection & customisation
The right model for each job: a frontier API, a Japanese-language LLM or an open-weight model, tuned on your domain data where it helps.
Secure, private deployment
Cloud, private cloud or on-premise, with access control, audit logs and your data kept where you need it.
Evaluation, guardrails & operations
Accuracy and hallucination testing before launch, guardrails on what the AI may say and do, and monitoring and retraining after (LLMOps).
02Our Strengths
AI × System DevelopmentEnabling Continuous Business Innovation
End-to-end development, from requirements to operations
One team takes your system from requirements and design through build, testing, release and ongoing support.
Vertical AI built around your industry
Models, data and workflows shaped around how your business actually works, whatever the industry.
LLM and AI agent engineering
Hands-on experience building LLM applications, RAG and AI agents, from prototype to production.
Governance designed in from the start
Security, access control and audit trails are part of the design, not added after launch.
03
Our Process
One consistent process for systems and AI alike, from the first conversation to life after launch.
Identifying Challenges
We learn your goals, processes and data, then agree the scope and the targets the project will be measured by.
- Business and process review
- Data readiness check
- Scope and success targets
Design, Development & Build
We design, build and test the system and any AI models in short cycles, with quality and security built in.
- Architecture and UI/UX design
- Development and AI model training
- Integration with existing systems
- Testing and accuracy validation
Operations & Improvement
After launch we monitor, support and retrain, so the system keeps pace with your business.
- Monitoring and support
- AI model retraining
- Updates as your business changes

Frequently Asked Questions
Do you handle system replacements or version upgrades?
Yes, we support system replacements and version upgrades. Our services include migration planning, data transfer, and integration adjustments to ensure a smooth transition.
How long does it typically take to develop a custom system?
Depending on the scope and complexity, a typical development project takes about 3 to 6 months. A detailed timeline is finalized during the requirements definition phase.
What are the main steps in the system development process?
Our development process includes the following steps: requirements definition, system design, development, testing, deployment, and ongoing maintenance. We work closely with clients at each step to confirm needs and deliver the most suitable solution.
Do you support specific development platforms (e.g., C#, React)?
Yes, we support a wide range of platforms including C#, React, Java, and Python. We select the most suitable technologies based on your existing environment and project requirements.
