Strengths
What we do in the workplace.
We learn the work before building, test with the people who use it, and improve what needs fixing.
Trace the work before choosing technology
Who receives what, where is it entered, and who decides? We examine the real workflow and the tools people already use. Adding AI is not our starting point.
Separate AI assistance from human decisions
AI can read documents and draft entries. Sending, approving, and billing need a workflow people can review. We design records and accountability along with convenience.
Build systems that work with existing tools
We review spreadsheets, accounting tools, and existing systems, then decide what to keep and what to change. Our engineers work across workflows and data through phased rollout and operation.
Carry one workplace's learning to the next
Shared problems can become reusable products. Totsugo.com, which supports document comparison and data entry, is one example. We connect custom work with product development.

QUESTIONS
FAQ
How are you different from other AI development companies?
Our engineers understand your workflows and build software connected to existing data and systems. We test it in practice and improve it with the people who use it.
Do you have experience supporting SMEs?
Yes. We have supported 40+ companies and individuals with order checks, shipping labels, AI advisory, technology selection, and AWS architecture. Our case studies describe specific engagements.
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.
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.
