Your digital product, built to perform seamlessly — from the first user to the ten thousandth.
We develop comprehensive full-stack web applications — frontend, backend, database, authentication, payments, and admin panel. Everything a digital product needs to operate, scale, and generate business.
A web app isn't just a representation of your business. It is your business.
A website communicates what you offer. A web application is where what you offer actually happens — it is the product itself. It’s the platform where your customers sign up, subscribe, and access your service. It’s the dashboard where your team manages orders, users, and operations. It’s the system that processes transactions, applies business rules, and makes decisions in real time.
For a company whose product is digital, the web app is not support infrastructure — it is the core asset of the business. Its technical quality, speed, scalability, and ability to evolve directly determine the customer experience, operational efficiency, and the speed at which the business can grow.
Building a web app involves making simultaneous decisions about the user interface, backend architecture, data model, security, infrastructure, and user experience — all of which are interdependent. The decisions made in the first few weeks of development determine how much it will cost to maintain, iterate on, and scale the product for years to come. There is no way to compensate for a poorly designed architecture by piling on more code.
We offer two options: Launch Build to bring a complete and professional product to market in the shortest possible time, and Scale Build to build from the ground up with the infrastructure that a growing product will need. Both are final, professional-grade products — the difference lies in the scale of the infrastructure, not in the quality of the work.
Is this the service you need?
Launch Build is for you if:
You have a validated idea or a business that needs its first digital product, and you want to bring a complete, well-built product to market as quickly as possible. You need authentication, user roles, an admin panel, data operations, and possibly payment logic. The goal is a professional product ready for your first users — with the option to add advanced infrastructure features as add-ons based on the project’s needs.
Scale Build is for you if:
Your product already has traction — or you know for certain that the volume since launch will justify it — and you want to build it with the infrastructure that allows it to grow without reengineering: Docker, staging, advanced CI/CD, job queues, monitoring, testing with 70%+ coverage, and Redis included from the start. It’s not a higher level of ambition—it’s a higher level of infrastructure for products that are going to scale.
An important note: Launch Build is neither a prototype nor an experiment. It is a complete, secure, and well-documented full-stack product—simply without the enterprise infrastructure layer that Scale Build includes by default. A well-executed Launch Build is directly upgradeable to Scale Build when the product needs it. The code is clean, type-safe, and documented precisely for that purpose.
Do you only need front-end or back-end development?
Not all projects require full-stack development. If you already have your own backend and need a React interface connected to it, the Frontend Only service covers exactly that. If you have a frontend and need the API and database, the Backend Only service is the way to go. Both adhere to the same quality standards and can be combined with any other service in the catalog.
When a webapp is complemented by other services:
A web app does not include the marketing site that attracts customers before they encounter the product—if you need both, they are separate projects that must be planned in coordination with one another. And once built, the web app can serve as the core to which automations, chatbots, and AI integrations connect, expanding what the product does without increasing the operational team.

Examples of estimated budgets by project type:
| Project type | Service | Price | Timeline |
|---|---|---|---|
| Simple SaaS MVP | Launch + email + analytics | ~€8,500 | 6-8 wks |
| Online store | Launch + Stripe + file storage + email | ~€11,200 | 8-10 wks |
| Online academy | Launch + Stripe subs + OAuth + cron + i18n | ~€13,500 | 10-12 wks |
| B2B SaaS | Scale + Stripe subs + OAuth + search | ~€18,500 | 10-14 wks |
| Robust ecommerce | Scale + payments + WS + i18n + PWA | ~€23,000 | 14-16 wks |
| Multi-tenant platform | Scale + multi-tenancy + WS + audit trail | ~€26,000 | 16-18 wks |
A CMS Site is a content site — it publishes, communicates, and ranks. It has no business logic of its own: it does not manage registered users, process payments, or execute server-side operations beyond serving content. A webapp is where business happens: authentication, data creation and modification, transactions, user-specific flows. Many companies need both — the site to attract, the webapp to operate.
Yes. We implement payment logic with Stripe as an add-on in both services — one-time payments, recurring subscriptions with trial period management and dunning, automatic invoices, and webhooks that sync payment status with user access in real time. We also offer integrations with PayPal and European payment gateways such as Redsys, Adyen, or Mollie for clients who require them.
Yes, and it is the most common path. The Launch MVP is built with the same stack, the same code standards, and the same modular architecture as the Scale Build — the difference is the infrastructure layer included by default, not the quality of the product. Adding Docker, staging, Redis, advanced CI/CD, and 70%+ testing on top of a well-built Launch MVP is a planned extension, not a rewrite. The cost of doing it later is higher than having planned it from the start, but the path is open.
A well-defined Launch MVP is typically in production within 6 to 10 weeks, and a Scale Build within 10 to 16 weeks. These ranges are indicative — actual timelines depend on the complexity of the project, the number of add-ons, the client's availability to validate at each phase, and the team's concurrent workload. What we do guarantee is that the scope is precisely defined before we start so that timelines are predictable from the outset.
Yes. If you already have your own backend and need a React interface connected to it, the Frontend Only service covers exactly that — custom UI design, 5 views included, integration with your existing API, starting at €3,800. If you have a frontend and need the API and database, the Backend Only includes API architecture, 5 CRUD resources, JWT authentication with RBAC, full security, and Swagger documentation, starting at €5,000. Both are available as standalone services or as a starting point for a subsequent full-stack project.
The included support covers project-related issues for 30 or 45 days depending on the service. For ongoing maintenance — dependency updates, monitoring, infrastructure management, deployment of new versions — the DevOps retainer is the most efficient way to keep it covered without each intervention becoming a separate project.
