Our services 
built for companies shaping the future

Complex web applications are yes!devs' core competency. We build digital products that internal teams can't build or scale — from greenfield architecture to complex zero-downtime migrations. Our technology foundation: Next.js, TypeScript, Contentful, Vercel and GraphQL.

Digitalization costs money, and part of it often comes from the state. We know the relevant programs, tell you honestly what's an option for you, and support you from application to implementation. One important note up front: the well-known federal program go-digital ended in early 2025, as did Digital Jetzt. Anyone seeking grants for a concrete digitalization project today will find them primarily at the state level, supplemented by nationwide offers. As a Hamburg-based agency, we support you especially closely through the Hamburg programs. Important: You must always submit the application before the project begins, otherwise the funding is forfeited. Funding conditions and deadlines change constantly. We check the current status with you before we start.

Your website or application should run efficiently, so you can focus on your core business. We take over technical operations, keep everything up to date and secure, and are there when it matters. With clear service-level agreements, proactive monitoring and a dedicated contact person.

Not every digital project starts big. Sometimes it's a cleanly integrated tag manager, a quick performance boost or an accessibility check that gets things going. Our Quick Wins are clearly defined services with a fixed scope — delivered fast, effective immediately.

Test ideas quickly and precisely before a large budget is committed. Most experiments fail — that's normal. We make sure that insight comes early, not after months of development. One in ten experiments hits the mark. You'll only find that one if you get through the other nine quickly and cheaply. We build working software, not slide decks. You get real results validated by real users and real technology. So you make your next decision based on facts rather than assumptions.

When your legal department asks whether you can prove the correct handling of customer data, we hand over the folder. We meet enterprise requirements professionally, documented and auditable. The difference from a freelancer isn't just capacity, but reliability and liability. Security, quality and legal compliance are not afterthoughts. They are the foundation that lets your company answer to auditors, enterprise customers and authorities. We deliver evidence, not promises.

Clarity before code. Before we build, we understand. Tech audits, architecture decisions and due-diligence processes that enable sound investment decisions. This consulting is also the right entry point when the next step isn't clear yet. We create the basis for decisions before budgets are committed and teams are set up.

Making systems talk to each other. When data is stuck in silos, processes are synced manually and APIs run side by side without connection, we solve it. We connect business systems, digital channels and data sources into one reliable whole, so information arrives where you need it. We've taken over and untangled other agencies' integration chaos. We know the typical breaking points between systems and build connections that run stably, are documented and can evolve.

Professional websites that go live fast and stay maintainable long term. We build sites that convince technically and stay editorially in your hands. No vendor lock-in, no hidden dependencies. Website development is the most common entry point into a lasting partnership and often the start of a more complex collaboration. What begins as a corporate site regularly grows into portals, applications and custom systems.
