/ What we do
Services
We focus on four core areas and support you from concept and development through operations after launch. We take on projects in a single area or across several.
Business Systems
Business systems
We develop custom business systems built around how each company works, covering orders, inventory, customers, projects, and more. Whether you're replacing operations run on paper, Excel, or fax or connecting to existing systems, we help from the workflow review onward.

Web & mobile apps
We develop web apps for membership services, booking, e-commerce, admin panels, and more, as well as iOS and Android apps and corporate websites. We cover multilingual support in Japanese, English, and Korean, rebuilds of existing sites, and improvements and maintenance after launch.

AI & automation
We build AI into everyday operations: reading documents and faxes, automating data entry, searching internal documents, and more. We design on the assumption that a person makes the final check, and take you from a small trial to production use.
Learn more →Cloud & Data
Cloud & data platforms
We build infrastructure on Google Cloud, AWS, and other clouds, migrate systems from on-premises servers, and handle containerization, configuration management, and monitoring. We also build ETL pipelines and data platforms for analysis, and take on day-to-day operations.
