WebApp&BusinessSystemDevelopment
Executives, business leads, and IT managers building order management, inventory, or internal workflow systems from scratch
Defined, small web apps and business systems with clear integration boundaries. Yakumo diagnoses complex legacy integration and AI work
Building a business system from scratch is the right call when SaaS doesn't reach your requirements. We develop on React, Astro, and TypeScript — and from day one we design for operations and updates driven by AI agents. Data structures, API boundaries, authentication, operational flows — everything is built to be operated both by humans manually and by agents automatically. Yakumo runs both our own products and client projects in parallel using this approach. We deliver implementation speed and long-term operability as one package.

What We Solve
What we solve
Order management, inventory, case tracking, internal workflows, customer-facing web services — the systems that anchor your operations are only as efficient as they fit your actual business. Mobile use is one operating requirement assessed within this consultation.
Defined, small web apps and business systems are delivered through SOKUTSUKU by YAKUMO after a structured consultation. Yakumo takes over when AI is central, the work crosses departments or legacy systems, or requirements themselves need discovery.
Business fit comes first. Technology is the means.
