Frequently asked questions

How long does a project take?

A company website usually takes 4 to 8 weeks. Mobile and web apps depend on scope; most first versions launch in 2 to 4 months. The proposal gives you an exact timeline.

How much does it cost?

Every project is quoted individually after the discovery call. You get a fixed price per phase before we start, with no surprises.

Can you improve a website or app I already have?

Yes. We can redesign, speed up or extend an existing product, or rebuild it if that is the better option.

Who owns the code?

You do. At the end of the project you receive the code, design files and access to every account.

Do you offer maintenance?

Yes. We offer monthly support plans covering hosting, updates, security and small improvements.
