Web app development
Need to ship faster than your current setup allows?
We partner with European founders to build web apps that move their business forward.
Who's it for
Founders building a new product
You have a defined product to ship and a business that's ready to back it. We turn that into working software in weeks, not months.
Founders with a live product
Your app is in the market and working. But adding features is getting harder, your team is stretched, or your previous developer disappeared. We pick up where they left off.
Founders who outgrew their stack
What got you here won't get you to the next stage. We migrate web apps off old stacks and aging codebases, Bubble apps included, with your live business protected throughout.
Founders past the prototype stage
You used AI tools to build the prototype yourself. You are ready to grow and need production code, senior engineering, and a team your users can rely on.
What we offer
Our web application development is about real software: user accounts, complex logic, payments, dashboards and integrations. It is the part of web development that runs your business, not landing pages or marketing sites. Whether you're starting from scratch, continuing someone else's work, or migrating off an old stack, we're the senior team you can trust to ship.
You'll work directly with our technical PM and engineers throughout — no middlemen. Clean design, weekly check-ins, daily Slack updates, shared task tracking.
What you'll get
Frontend
Clean, responsive interfaces that work on any device. Carefully designed and built in modern frontend frameworks.
Backend
The logic that runs your product — user accounts, permissions, payments, complex workflows. Everything that happens behind the scenes.
Database & Integrations
A structured database for your business, plus integrations with Stripe, your CRM, email tools, or anything else your app needs to connect to.
QA & Testing
Rigorous bug-checking, performance testing, and a smooth handover. We make sure your app works in production — not just during demos.
Why founders work with us
- We've done it before. We've built many web apps and made the mistakes in the past, so you don't have to. We know what it takes to ship working software for live users.
- We treat your product like our own. We advise as a partner. Honest scope. Sharp focus. Constant simplification. Every feature you don't build is a feature you don't have to maintain.
- You'll know what you're paying for. Clear scope. Agreed budgets. Predictable delivery. No surprises. If you can save money by simplifying — we'll tell you.
- A long-term partner, not a vendor. Most of our clients work with us for years. You'll talk to the founder and the developers actually building your software — not a sales rep handing you off after the contract is signed.
The web app development process
Scoping & prototyping
We turn your idea into a clear plan and usually build a working prototype alongside it. You see real software within days — not months of discovery.
UI/UX Design
Once we know the direction works, we move to design in Figma. Full style guide, high-fidelity screens, and any branding or marketing assets you need.
Development
A senior team builds in short sprints, using modern tools and AI coding to ship fast without cutting corners. Weekly progress updates, so you always know where things stand.
Launch & beyond
We launch with you — and stick around. Most clients become long-term partners: we iterate, support, and evolve the software as the business grows.
You have questions?
We have answers
How much does it cost to build a web app?
It depends on scope and complexity, but as a guide: a prototype starts at around €2,500, an MVP (a first version for real users) at €5,000 and a full product at €10,000. Most web apps we build cost between €10,000 and €50,000. We usually work with fixed-price scopes against agreed budgets, so you know what you are paying upfront. Book a call and we will give you an estimate for your project, or read our guide to web app costs.
How long does it take to build a web app?
It depends on scope, but we measure in weeks — not months. A prototype usually takes about a week. A first version of a new build is around a month. For new projects, we recommend keeping scope tight and launching fast. Larger migrations with live users can take longer — but we'll give you a clear estimate before we start.
What is the difference between web development and web app development?
Web development covers any website, from a simple marketing site to a complex platform. Web app development is the part where users log in and get work done: accounts, permissions, data, payments and workflows. That is what we build. If you only need a marketing website, we are not the right fit.
What technology will you use to build my app?
It depends on what your project actually needs. For new web apps, our default is Next.js, Supabase, Vercel, and TypeScript — a modern fullstack that's fast to build and easy to scale. We also work in Bubble when it's the right call. We use AI tools like Claude Code throughout — they help us ship faster without lowering the quality of the code you'll end up with.
Is it safe to use AI to build my web app?
Yes, when senior engineers stay in charge. We use AI coding tools like Claude Code to write and check code faster, but an engineer reviews every change, and the code is tested and kept in your own repository. AI makes the work faster. It does not replace the review.
Do I own the code and the app?
Yes. For modern fullstack projects (Next.js, Supabase, etc.), your code lives in your repository, your data in your accounts, your hosting in your name — full ownership, no lock-in. For Bubble projects, you own the app and your data, though you'll always need a Bubble subscription to run it. Either way, you can take the work elsewhere whenever you want.
Can you take over from a previous developer?
Yes — this is one of the most common ways founders come to us. We start with a review of the existing codebase and give you a clear written take on what's salvageable, what should be rebuilt, and what it would take to get moving again. From there, you decide whether to continue with us.
Should I build a web app or a mobile app?
For most B2B products, start with a web app. It works on any device with a browser, you maintain one codebase, and every user gets updates at once without app store reviews. Add a mobile app later if your users need features like offline use or push notifications. Read more in web app vs mobile app.
What do I need to prepare before we start?
Not much. A short description of the problem, who your users are and what the first version must do. If you have designs, an existing app or documents, share them. We turn that into a clear scope in the first step. Our guide to building a web app explains the steps.
What happens after launch?
Think of us as your long-term technical partner. We stay around to support you — bug fixes, new features, evolution as your app grows. That can be on an hourly basis or, if you have a steady workload, on a monthly retainer. Whatever fits your business best.
