WebApp Development

WebApp Development

Your own system instead of a rented patchwork.

Past a certain size, your software is the brake, not the lever. Processes running manually. Tools that do not work together. A system that does not follow your growth — it slows it down.

We build the infrastructure that maps exactly to your business — delivered to fixed milestones, owned by a single accountable contact, with full code ownership and EU data sovereignty. A system that scales with every step of growth instead of needing to be rebuilt.

Benefits

Why an owned system over off-the-shelf.

What sets a built system apart from rented software.

Software that carries your growth — not brakes it.

01
SVG-Asset

Past a certain size, standard software becomes the bottleneck. Your WebApp is built to take on load, processes and teams as you scale.

Delivered to plan, not just promised.

02
SVG-Asset

Fixed scope, fixed milestones, a fixed point of contact. You invest in a dated outcome, not an open-ended project.

Full control over system and data.

03
SVG-Asset

Full code ownership, EU-hosted, auditable. No dependence on a third party's roadmap or outages.

A partner who stands behind it.

04
SVG-Asset

No ticket system, no anonymous hotline. One contact who knows your system and is accountable for it beyond launch.

One system, not a patchwork.

05
SVG-Asset

Workflows, data and interfaces converge in one system — a single source of truth instead of five tools that don't talk to each other.

Manual work disappears.

06
SVG-Asset

What's copy-paste between spreadsheets and tools today runs automatically — your team wins back hours every week.

  3. 03

    A decision at business level: a system is infrastructure, not a tool trial.

Ardamedia

Better Rankings, More Revenue, Less Headaches, Full Control.

Arda Media is a social media agency based in Cologne that helps businesses develop and execute social media strategies. Despite strong operational work for their clients, the agency itself lacked any professional digital infrastructure: no website, no unified brand identity, no system for managing inquiries, and no way to be found through search engines. Gawenda Studio built Arda Media a complete digital platform from scratch — including a custom-coded website, a bespoke CMS, an inquiry flow, and an SEO strategy built on owned content rather than hope.

Testimonials

Our satisfied clients

Experiences from clients who have built digital systems with us – honest, direct and from practice.

Before this I only had a basic site-builder page

What I love most is that I can now add or change content myself, without any technical know-how. Hit save and boom — it's live!

FAQ

Frequently Asked Questions

Frequently asked questions about web app development

The starting price is shown transparently above — the final price depends on the scope, which we fix together up front. You get a fixed scope and fixed milestones, not an open-ended hourly budget that drags on. Before the first cent, you know what you're getting.
Typically weeks, not quarters. We deliver along fixed milestones with a clear timeline — after every step you see working software, not status reports. The exact schedule is set before we start.
Completely. You get full ownership of the code — no licence model, no dependency on our roadmap, no vendor lock-in. The web app is your infrastructure, not a tenancy.
Past a certain size, standard software becomes a brake: processes that don't fit, tools that don't talk to each other, workarounds that cost time every day. A custom web app is built exactly around your business logic — one system instead of a patchwork, with a single source of truth.
Everything is hosted in the EU on infrastructure under your control (e.g. Hetzner), auditable and GDPR-compliant. No third party in the critical path, no data leaking away uncontrolled.
You have one fixed point of contact who built the system and stands behind it beyond build and operation — no ticket roulette, no anonymous hotline. The system grows with new user groups, processes and load, instead of you starting over in 18 months.
Yes. We integrate existing systems instead of duplicating them — from CMS and CRM to payments (e.g. Stripe) and your hosting environment. Workflows, data and interfaces come together in one system.
Less than you'd think. It takes one first conversation in which we pin down scope and goal together — concept, structure and milestones are on us. You don't need a finished specification, just the willingness to think your business through properly once.
