Four reasons to hand indirect work to AI
"AI-only" specialist
AI moves fast. Yesterday's common knowledge gets old today. As an AI-only specialist, we keep up with the latest papers and trends every day. We don't just "try AI somehow" — we propose solutions based on the latest technology. The Japan Software Science Society invited our CEO as a lecturer alongside professors from UTokyo and AIST — recognition from the academic world.
Thoroughly "start from the field"
No matter how great the technology, it's worthless if it's not used. Before we build, we watch your team's actual work — who does what, when, and how. Then we design AI that fits naturally into daily work, without adding burden.
One team that does everything
Our CEO holds all 12 AWS certifications. Our team includes former Toshiba engineers who can do everything from infrastructure to the user-facing screen. We don't just consult — we own the whole journey, from quick pilots to production systems that hold up under real load.
Specialist in eliminating indirect work
Invoice checks, Excel entry, document matching — the 5 to 8 hours of daily indirect work that AI takes over. Totsugo.com automates document matching, and our AI Tech Advisory helps you decide what to hand to AI first. We've supported 40+ companies and individuals, from listed corporations to sole proprietors.

FAQ
Q. How are you different from other AI development companies?＋
We don't start with AI tool selection. First we map your workflows, documents, existing SaaS, and verification work. The difference is that advisory, quote reviews, custom development, and operational improvement all connect in the same context.
Q. Do you have experience supporting SMEs?＋
Yes. From order checking, shipping labels, AI advisory, technology selection, and AWS architecture reviews, we have supported 40+ engagements from listed companies to sole proprietors.
Q. Can we hire you for technical advisory alone?＋
Yes. We can support pre-development decisions only — AI adoption strategy, vendor quote reviews, PoC design, and existing SaaS integration.
Q. Can we consult even if our systems are old?＋
Yes. Instead of replacing everything at once, we start from the environment your team actually uses — Excel, PDF, email, freee, COREC — and find what can be automated.
