We help clients reach their next step through AI and software craftsmanship.

AI Engineering Services

AI開発支援

Redesigning business with AI — from prototype to production.

We design and ship business applications powered by LLMs end-to-end — architecture, implementation, and production operations. RAG over internal documents, agent workflows for real business operations, Japanese-language fine-tuning, on-prem and hybrid deployments. We start from the problem, not the prompt.

LLM application design (RAG / agents / function calling)
Eval and ops foundation (accuracy monitoring, cost control)
On-prem and air-gapped deployments (finance, health, public sector)

Cross-Border Product Development

越境プロダクト開発

Products that ship across Japan, China, and North America — built by one team.

We specialize in two-way cross-border product work: bringing Japanese SaaS into Greater China and Southeast Asia, and adapting overseas products for the Japanese market. Bilingual JP/中/EN engineering teams handle design, implementation, regulatory alignment, and i18n architecture, including full localization. We deliver one product across cultural boundaries.

i18n / l10n architecture (multi-language, multi-currency, multi-tax)
China-region performance and delivery (HTTPS, DNS, CDN strategies)
Multi-jurisdiction compliance (GDPR / PIPL / APPI / PIPA)

DX Consulting

DXコンサルティング

Practical DX for small and mid-sized businesses. We build, not just slide.

Practical transformation that works on the floor of Japanese SMBs. We rebuild business processes long-run on Excel — accounting, HR, workflow, contract management — with AI and automation. Beyond vendor selection: we walk through migration, training, and operation with you. Not consultants — partners who get hands dirty.

In-House Products

自社プロダクト

Building our own tools — and putting them in everyone's hands.

We invest the experience from client work back into our own products. Several tools are already running internally; we will release them externally as they reach the bar. Details to come.

Currently in stealth — details coming soon
AI-first productivity tools
Built with Japan, Greater China, and North America in mind
