Custom app and MVP development: a working app in weeks, not months
We design, build and run custom apps for businesses and founders: MVPs, SaaS products, client portals and internal tools that work on desktop and mobile. We use AI throughout development, so the first working version is ready in weeks. You get a fixed price and an app that works for real users.
Apps we built and you can check

Discover VistobiWhat kind of app do you need?
MVP development and SaaS products
From data model to paying users: accounts, subscriptions, dashboards and AI features. DogDietLab went from idea to a working first version in about two weeks.
Client portals
A place where your clients log in, upload documents, follow their orders or book appointments, instead of sending emails back and forth.
Internal tools
Replace spreadsheets and email threads with a tool built around your process: forms, approvals, roles, reports and notifications.
AI features in your app
Assistants, photo and document analysis, and generated content with a human review step. Agrider's valuation tool uses photos to assess a machine's condition.
Integrations and automation
XML and CSV product feeds, Google Drive, Google Sheets, Search Console, email notifications and scheduled jobs.
Rescue and takeover
Started an app yourself, or with an AI app builder, and got stuck? We review it, fix the data model and logic, and get it ready for real users.
MVP development services
Have an idea and need to know whether people will pay for it? We build a focused MVP: the smallest version real users can sign up for and use, with accounts, payments and AI where they matter. DogDietLab's first working version took about two weeks, and it now runs in 24 regional versions.
Scoped in one call
We cut the idea down to the features that prove it works. You get a fixed, itemised quote, so you know the MVP development cost up front.
AI-assisted MVP development
AI coding tools handle the routine work, so the MVP is ready in weeks. We plan, test and check every change before it goes live.
Built to grow
The data model, roles and hosting are set up for real users from day one, so you extend the MVP instead of rebuilding it.
Why AI-assisted development is faster, and still safe
We use AI coding tools for the routine part of the work, so a first version takes weeks instead of months. Planning, the data model, permissions, testing and launch stay with us, and every change is checked by a person before it goes live. Your app can also be found on Google if it needs to be.
- First working version in weeks: DogDietLab took about two weeks.
- Hosting, database and user accounts included, with no separate server bills.
- Roles and permissions, so everyone only sees their own data.
- Works in the browser on phone, tablet and desktop, with nothing to install.
- Native URLs, hreflang and sitemaps when the app has public pages (Agrider: 2,463 URLs).

When we are not the right choice
If you need a standard webshop with ready-made payment, shipping and stock plugins, Shopify or WooCommerce is usually faster and cheaper. If you need a native app in the App Store, or company policy requires hosting on your own servers, a classic development team fits better. We tell you this in the first call.
Frequently asked questions
How much does custom app or MVP development cost?
An app or MVP with custom logic, user accounts or AI starts from €2,000. The final price depends on the number of screens, user roles and integrations. You get a fixed, itemised quote after a 30-minute call.
How long does it take to build an app?
A focused MVP usually takes weeks rather than months: DogDietLab's first working version took about two weeks. Larger systems such as Agrider are built and extended step by step.
How do you use AI in development?
We use AI coding tools for the routine parts, which is why we are faster. Planning, the data model, security, testing and launch are done and checked by us.
Does the app work on mobile?
Yes. Our apps run in the browser on phones, tablets and desktops, with nothing to install. If you need a native App Store or Google Play app, we discuss it in the first call.
Can you take over an app we started ourselves?
Yes, also if it was started with an AI app builder. We start with a short review of the data model, logic and security, then give you a fixed quote for fixing and finishing it.
Who owns and administers the app?
The proposal states who administers the hosting, the domain and analytics, and what we hand over at the end of the project.
