FAQ
Do I own the code, accounts and IP?
Yes, 100%. We build from scratch, the code lives in a repository you control, and every account and key is handed over with documentation. Any developer can continue the work after us.
Do you build the whole thing, including backend, infrastructure and deployment?
Yes. Frontend, backend, database, authentication, third party integrations, hosting setup, deployment and store release. You get one team responsible for the entire product, so nothing falls between two vendors.
Can you take over a project another developer started?
Yes. We start with a code audit so you know exactly what you have, what works and what needs fixing, with a priority for each item. Then you decide what to do next with real information instead of guesses.
How much will my project cost?
You get a realistic cost and timeline on the first call, after we understand your scope. We do this so the number we give you is one we can stand behind, instead of an estimate that changes later. Fixed scope, fixed price.
Can we start small before committing to the full build?
Yes. Every project starts with a paid discovery phase of 1 to 2 weeks. You get the full plan, design, timeline and exact budget before any coding. Not happy with it? 100% refund. The fee is credited toward development if you continue.
How long does an MVP take?
Core features usually take 4 to 6 weeks. A full app is typically 8 to 12 weeks. Bigger builds take longer, and you know the timeline before any coding starts.
What happens after launch?
The first 30 days of bug fixes are included. After that we offer maintenance and further development tailored to your needs, so you are never left without support when real users show up.
What tech stack do you use, and why?
Next.js for web apps and admin panels, NestJS with PostgreSQL for the backend, React Native with Expo for iOS and Android. These are widely used and well supported, so your product is easy to maintain and easy for any future developer to pick up. We recommend changes when your project needs them.
Can I see examples of similar work?
Yes. Tell us what you are building and we send live links, demos and screenshots of the closest projects we have done. We match the examples to your type of product, so you can judge the fit instead of browsing a general portfolio. FYI: Some projects might be under NDA preventing us to share it.
Can you build AI features like voice agents and chatbots?
Yes. Voice agents for inbound and outbound calls, chat assistants, content generation and AI integrations into your existing tools. We choose the providers for your case and explain the monthly running costs before we build, so there are no surprises on your bill.
