FAQ

What clients ask us most.

How much does an app cost?

It depends on complexity: number of screens, integrations, platforms and design depth. After a short discovery call we send a clear, phased estimate with no hidden costs.

How long does development take?

A well-defined MVP usually launches in 6–12 weeks. We deliver more complex products in stages, with working versions along the way so you can test early.

Who owns the source code?

You do. At the end you get the source code, access to every account and the documentation. No lock-in, no dependency on us.

Can you take over an existing app?

Yes. We run a technical audit, stabilise what needs it and continue development — on our own or alongside your team.

Do you offer maintenance after launch?

Yes. We offer maintenance and ongoing development: updates, monitoring, security and new features, driven by a shared roadmap.

Do you implement AI solutions?

Yes. We build AI agents, MCP servers, process automation and assistants that answer from internal documents, securely integrated with your existing systems.

Do you only work with clients in Romania?

No. We are based in Romania and work remotely with clients across Europe and beyond, in English or Romanian.
