替企業做 App、數據、自動化與增長。從規劃到上線,全程負責。

First call is free. No deck, no proposal, just a straight answer on whether it can be built and roughly what it costs.

1

You talk to the people doing the work

每次通話、每次 demo,都是實際負責專案的人,需求不會在轉手中走樣。

2

We run our own products

我們營運自己的產品

Our apps are live, paid and subscribed to by real users. We know what store rejection, refund disputes and churn look like because we deal with them.

我們的 App 真的有人付費訂閱。商店退件、退款爭議、用戶流失長什麼樣——我們每天在處理。

3

Fixed price, written down

固定價格,白紙黑字

Scope, price and delivery date on one page before we start. Change requests are quoted, not absorbed and billed later.

FAQ

Things people ask on the first call.

第一次通話常被問到的事。

How much does an app cost?做一個 App 要多少錢?

It depends on what it does, not how it looks. A focused internal tool is a different job from a consumer app with payments and push. Tell us the problem on the call and you'll get a written number after the call.

看它做什麼,不是看它長什麼樣。一個專注的內部工具,跟一個含付款與推播的消費者 App 是兩種工作。通話時告訴我們問題,通話後給你白紙黑字的數字。

Who owns the code?程式碼歸誰?

You do, on final payment. Repository, store accounts, domains — all in your name from day one.

付清尾款後歸你。程式庫、商店帳號、網域——從第一天起就用你的名字開。

Do you use AI to write code?你們用 AI 寫程式嗎?

Yes, the way a good carpenter uses a nail gun. It makes us faster; it doesn't make the decisions. Everything shipped is reviewed, tested and understood by a human who will answer for it.

用,就像好木匠用釘槍。它讓我們更快,但不做決定。交付的每一樣都經過人的審查、測試與理解,而且那個人會負責。

Can you take over an existing app or database?能接手現有的 App 或資料庫嗎?

Usually. We start with a paid two-week audit so nobody is guessing about the state of the code.

通常可以。我們會先做付費的兩週健檢,讓大家都不用猜程式碼的狀態。

Are you a registered Hong Kong company?你們是香港註冊公司嗎?

Cudris Limited (鍛承有限公司) is a Hong Kong private limited company. We invoice in HKD or USD and can sign standard NDAs.

Cudris Limited(鍛承有限公司)是香港私人有限公司。可開港幣或美元發票,可簽標準保密協議。

What if I just need advice?如果我只是需要建議?

Start with a short call. Hourly consulting is also available — useful if you're evaluating vendors or a technical hire.

前 30 分鐘之後可按小時諮詢——在你評估供應商或技術招聘時很有用。
