FAQ

Frequently Asked Questions

What kind of company is DnD Inc.?
We are a Japan-based development partner. We build custom software and systems with AI at the core — AI integration, web and business systems, apps, and automation — from requirements to operation. We also offer an operations-efficiency package (operation improvement, BI-tool replacement, SaaS replacement). We create value by building only what's needed, not by adding technology.
What is the "Operations Efficiency DX Package"?
It is a three-pillar service that removes excess from work that tends to be costly, complex, and person-dependent: Operation Improvement (automating and standardizing manual, person-dependent work), BI Tool Replacement (replacing costly BI tools with an AI-driven dedicated dashboard), and SaaS Replacement (replacing costly SaaS with a lightweight, industry-specific system).
What areas do you serve?
We work nationwide across Japan, primarily online. Our office is in Omiya Ward, Saitama City, Saitama.
How much do your services and estimates cost?
Consultation and estimates are free. After hearing your operational challenges, we pin down only what you truly need and provide an estimate based on the requirements.
Can small companies or sole proprietors work with you?
Yes. We welcome clients of any size, including those still at the "we don't know where to start" stage.
What is the flow from consultation to development?
Inquiry → hearing your challenges → proposal and estimate → requirements definition → development → operation and maintenance. We stay with you throughout.
