Five steps, each with a time box and deliverables you can hold us to. You see working software early, steer as you learn, and your code lives in your own repository from day one.
Every step ends with something you can see, test and keep — so you always know where the project and the budget stand.
Step 01Typical duration: 1–2 weeks
Workshops with your team — and your users, where possible — to map goals, constraints and risks. We leave with a shared definition of what a successful first release looks like.
You receive
Step 02Typical duration: 1–4 weeks
User flows, a visual system and a clickable prototype, tested with real users before production code begins. For AI and games, we prototype the model behaviour or the core loop first.
You receive
Step 03Typical duration: 2–12 weeks
Two-week sprints, each ending in a demo on real devices, plus a short written update every week. You steer priorities as you learn and always know where the budget stands.
You receive
Step 04Typical duration: 1–3 weeks
Automated and manual QA across devices, load and security checks, then a staged rollout. We handle App Store, Google Play and WeChat reviews and stay on call through launch week.
You receive
Step 05Typical duration: Ongoing
We watch the numbers with you, fix what users trip over and ship improvements on a steady cadence — or hand everything to your team with full documentation and training.

Four habits that keep projects transparent — and keep surprises out of your inbox.
01
Every two-week sprint ends with a live demo on real devices, and a short written update arrives every week. You judge progress by working software, not slides.
02
Both teams work from the same task board. Priorities, progress, open questions and budget used are visible any day — no status meetings needed.
03
One accountable lead owns scope, timeline and communication — in Cantonese, Mandarin or English. One message gets you an answer.
04
Our own tools — Hlool PDF, HloolMail and Shuiyin — are open source, so you can read our code before you hire us. Your project gets the same clean, documented code.
Browse our open-source workSame team, same standards — only the commercial shape changes. Not sure which fits? We’ll recommend one after our first call.
A clearly defined product or release, delivered for a fixed price on an agreed timeline. Scope is locked after discovery, and any change goes through a simple written change request.
MVPs, campaign mini programs and well-defined first releases
A stable squad — product, design, engineering and QA — working as an extension of your company and billed monthly. Scale up or down with one month’s notice.
Live products, games in operation and long-term roadmaps
A time-boxed engagement of two to six weeks that answers one hard question: is this AI use case viable, which engine fits, will the architecture scale? You get a working prototype and a clear recommendation.
Validating AI ideas, technical due diligence and architecture reviews
Something else on your mind? Our AI assistant, powered by SHUAI API, answers from everything on this site — or write to us directly.
In one of three ways, matching our engagement models: a fixed price for a defined scope, a monthly fee for a dedicated team, or a set fee for a time-boxed consulting engagement. Every estimate is itemised, so you can see what drives the cost — and trade scope for budget if you need to.
It depends on scope. As a guide, a focused mini program or AI pilot is typically planned at 4–8 weeks, products with deeper integrations at two to four months, and casual games at three to six months, with bigger titles taking longer. Whatever the project, you’ll see working software at the end of the first two-week sprint.
You do. Once the related invoices are paid, all source code, designs, documentation and any models trained on your data belong to you — in repositories you control from day one. Open-source components keep their own licences, and our own pre-existing, general-purpose tooling comes with a perpetual licence for use in your product.
Yes — we’re happy to sign your NDA before any detailed discussion. We work on least-privilege access, keep data in your own cloud accounts wherever possible, never use it to train models for anyone else, and handle personal data in line with Hong Kong’s PDPO and, for mainland users, the PIPL. Sensitive AI systems can be deployed privately on your own infrastructure.
Every project includes a 60-day warranty: defects we find or you report are fixed at no cost. After that, you can choose a monthly maintenance plan with agreed response times — covering monitoring, OS and platform updates, security patches and small improvements — or take everything in-house with a full handover.
Send a few lines about your idea through the contact form or by email. We’ll reply within one business day and set up a free 30-minute call. Fixed-scope projects are paid in milestones — typically 30% at kickoff, 40% at beta and 30% at launch — while dedicated teams are billed monthly.
