From first contact to launch and beyond — four predictable steps.
Send us a message. We will set up an online consultation as soon as we review it. In-person meetings are available in the Tokyo metropolitan area.
Within 1 week, we send a written summary covering scope, phased timeline, and a rough quote.
We share a working build every week, plus a recorded demo and change notes — so you can track progress without standups.
We launch with you, then optionally stay on as the operations team — or hand off to your team with bilingual documentation.

Four reasons international and domestic clients pick us.
Continuity
The person who scopes your project is the one who builds and operates it. No account-manager handoffs, no information loss, immediate technical decisions.
E-commerce expertise
We have shipped Shopify and MakeShop stores, inventory / fulfillment / WMS integrations, POS systems, and order automation for over a decade. We design for peak season from day one — not after the first outage.
Bilingual delivery
Specs, API docs, code comments, and handover notes — all available in either English or Japanese. Hand off naturally to a JP team after launch, or work with us entirely in English from the start.
Reliability first
We pick boring, battle-tested tools over the latest hype. SvelteKit, Astro, Django, Cloudflare, AWS — stacks we have run in production through outages, migrations, and scale-ups, not just in slide decks.
In production with
Selected partners running our code in their day-to-day operations. Logos only — engagement details available on request under NDA.
