SERVICES

From AI-native business app development
to secure operations of existing apps

01

AI-Native Business App Development

We develop AI apps tailored to your needs: operational efficiency, inquiry handling, report generation, data utilization, and more. From requirement analysis to design, development, and post-launch improvement, we aim to deliver apps that truly work in practice.

  • Operational Efficiency
  • Internal FAQ
  • Auto Report Generation
  • Knowledge Utilization
02

Infrastructure Design & Operations

We combine domestic and international cloud services, VPS, dedicated servers, and AI APIs to propose a balanced architecture in terms of cost, security, and scalability. We avoid over-engineering and aim to minimize monthly expenses.

03

Security Review
for Existing Apps

For apps built by internal staff or individuals, we review authentication, permissions, data storage, API key management, communication security, logging, and backups to identify risks for production use.

04

Operational Framework
with GitHub

We establish source code management, version history, deployment procedures, backup strategies, incident response, and update workflows for safe, continuous operations.

05

Maintenance & Improvement

We provide ongoing support after launch: bug fixes, improvements, feature additions, and security reviews. We don't just build and walk away — we help your app evolve with your business.

ISMS Certified (ISO/IEC 27001)

We are certified under the international standard for Information Security Management Systems (ISMS). We properly manage our clients' information assets and deliver services under a consistent security framework from development through operations.

SECURITY REVIEW

Is your self-built app really
safe for production use?

With AI coding tools and no-code platforms, anyone can build an app today. However, apps handling internal data or customer information are sometimes deployed without adequate security or operational planning.

Our service helps you assess the safety and operational readiness of apps already in use, and organize the improvements needed.
