We build & ship full products.
We turn fintech and AI ideas into secure, production-grade apps — payments, AI features and the whole product around them — shipped fast, with one point of contact from idea to launch.
Start a project →Everything a product needs — under one roof.
Like a black hole, we pull every part of your product into one orbit — the app your users touch, the API behind it, the cloud it runs on, and the hard parts in between. Most freelancers hand you a piece; we own the whole slice.
Mobile apps
One app that runs on both iOS and Android, feels truly native, keeps working offline, and goes live on the App Store and Play Store.
Backend & APIs
The engine behind your app — fast and scalable, secure and properly tested, with your data handled safely by default.
Cloud & infra
Hosting that stays up and stays fast anywhere in the world — with automated releases, backups and monitoring built in.
AI & payments
Smart features like document reading and chat assistants, plus real payment flows — cards, PromptPay and LINE Pay — wired in properly, not bolted on.
Broad, with a sharp edge.
We cover the whole build — and adapt to whatever you already have. The real specialty isn't any one tool: it's shipping complete, secure products, fast.
Shipped, not slideware.
Real products taken end to end. Public ones link out; private client apps show the shape of the work only.
