Let’s connect

Webflow Agency

In Webflow, we build websites that look like custom designs but are as easy to maintain as a ready-made platform. Your team can update content on its own, without servers or plugins.

Webflow Agency

Webflow combines design, a CMS, and hosting into a single system. We use it to build websites that go live quickly, look great, and are easy to maintain—without having to compromise on themes and without any technical maintenance work for your team.

When Webflow Is the Right Choice

Webflow is a good fit for companies that want to quickly launch a visually stunning website without having to run their own server. If your focus is on marketing sites, landing pages, and content, and you value animations and a simple content management system, Webflow really shines. We’ll give you honest advice on whether Webflow is the right fit for your project, or whether WordPress, TYPO3, or HubSpot CMS would be a better choice.

How Your Team Works with Webflow

After launch, you’ll manage content using the Webflow Editor, right on the page. You can edit anything you click on without affecting the layout. Structured content—such as blog posts, projects, or team members—is organized into CMS collections with clearly defined fields. This ensures your pages remain consistent, even when multiple people are managing them. We’ll add new pages or sections as your needs grow and the design needs to evolve accordingly.

From corporate websites to landing pages to site relaunches: What we build with Webflow is based on what you really need. Every project starts with your goals, not with the platform's features.

Company Websites

Custom corporate websites with a clear structure, clean code, and a design that doesn't look like it was built with a template. In Webflow, we design every element from scratch instead of relying on a theme.

Landing Pages

Fast, high-converting landing pages for campaigns and promotions. Thanks to Webflow, they go live quickly, with custom designs, forms, and tracking. This is ideal when speed is of the essence.

Blogs and Content Websites

Blogs, magazines, and project overviews based on CMS Collections. You manage articles, categories, and authors using clear fields, and the layout automatically remains consistent. This way, your content grows without making the site look cluttered.

Relaunches and Migration

If your website is outdated or runs on a different system, we'll help you migrate it to Webflow. See below for a detailed description of the process.

Animations and Interactions

Webflow adds movement to your site without any extra code. We design scroll effects, hover animations, and transitions that bring your site to life. We use them sparingly so that the animations support your message rather than distract from it.

Accessible Websites

The Accessibility Enhancement Act has been in effect since June 2025. We build Webflow websites in accordance with WCAG 2.1 guidelines, using semantic HTML, keyboard navigation, and a structure that works with screen readers.

These companies know how we work

In Webflow, we design visually, but the result is real, clean code. Every element sits exactly where it belongs, without the compromises of a pre-made theme. We work with clear class structures and a well-thought-out style guide to ensure the site remains consistent and is easy to expand. Unlike many website builders, this results in semantic HTML that search engines and screen readers can easily understand. For features that go beyond the standard functionality, we add our own code directly within Webflow. This combines the speed of visual development with the freedom of traditional programming. You’ll get a website that looks unique and is technically sound.

Requirements and Concept

Together, we’ll determine what your website should accomplish: target audiences, page structure, content, animations, and integrations. This will result in a concept that includes the site architecture and the appropriate technical framework. During this phase, we’ll also decide which content should be stored in CMS collections and where static pages make more sense. This way, both sides know from the start exactly what the project entails.

Design and Prototype

We develop the visual design based on the concept. You’ll see drafts for the most important page types, provide feedback, and we’ll refine the design until we’re satisfied with the result. From the very beginning, we consider how the design can be implemented in Webflow and easily maintained later on. This saves time during development.

Setup in Webflow

We implement the design in Webflow: structure, styling, CMS collections, and animations. Each collection is assigned clearly defined fields, and each element has a clean class structure. Where necessary, we add custom code or integrate external services. We set up forms, tracking, and redirects so that they work right from day one.

Testing and Launch

Before the go-live, we’ll test the site in a staging environment: functionality, performance, behavior across all devices, and accessibility. Your team will receive training on the editor and will be able to manage initial content on their own. Once everything is set up and you give the green light, the site will go live. After that, we’ll remain available for enhancements and new requirements.
