Founded by veteran engineers. Tokyo-based product studio.
We plan, develop, and operate our own web services and products to solve challenges in specific domains, handling everything in-house from planning through operation.
We have experience in developing e-commerce shops, logistics and inventory management systems, point-of-sale systems, AI agent chatbots, and more.
Passveil is a free tool for securely sending files via email. Upload files to cloud storage with an expiration date and send secure download links to recipients. Ensure security with password protection and automatic deletion.
AmbientBGM is a free BGM player that continuously plays unobtrusive music. Perfect for remote work, cafés, waiting rooms, retail stores, meditation, or sleep. No ads — all tracks are AI-generated.
DomainHike is a free tool for searching .com domains and recording search history. AI helps you find available .com domains from your ideas, assisting you in discovering truly usable domains.
Support Node is an email support management tool for business startups. Centralize your inbox, assign responsibilities, and use AI-generated reply drafts to reduce response time and prevent missed or duplicate responses.
From first contact to launch and beyond — four predictable steps.
Send us a message. We schedule a 30-minute online call within 2 business days.
Within 1 week, we send a written quote with scope, deliverables, and a phased timeline.
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.
Transparent quotes. Anything outside scope is explicitly listed and re-quoted up front — no surprise invoices.

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.
