Does this sound familiar?

Spreadsheet chaos instead of systems

Your teams are juggling Excel sheets, email chains, and manual processes? That costs time, creates errors, and simply does not scale.

Off-the-shelf software falls short

Salesforce, SAP, or HubSpot cover 70% of your needs, but the critical 30% is missing? Customization ends up costing more than a tailored solution.

Legacy systems holding you back

Your existing software is slow, outdated, and developers no longer want to touch it? Every month you wait makes migration more expensive.

How we solve it

Our approach in detail

Custom Web Applications

Custom Web Applications

ReactNext.jsTypeScriptTailwind CSS

We don't build websites, we build web applications. The difference: a website informs. A web app digitizes your business process.

From customer portals and internal dashboards to complex SaaS platforms, every application is tailored exactly to your requirements. Building on React and Next.js means fast load times (Server-Side Rendering), excellent SEO, and an architecture that grows with your business.

Our web apps are designed for integration from day one. REST and GraphQL APIs connect your web platform with existing systems: ERP, CRM, payment, email, analytics, all through clean, well-documented interfaces.

Cloud-native deployment on AWS or Azure means automatic scaling, 99.9% uptime, and operating costs that reflect your actual usage.

SaaS Platforms & Multi-Tenant Architectures

Looking to offer your software as a SaaS product? We build the technical foundation: multi-tenant architecture, subscription billing (Stripe), user management (Auth0), automated onboarding, and self-service dashboards.

From database isolation to pricing models, we think through your SaaS product end-to-end, not just the code.

Frequently Asked Questions

What is the difference between a website and a web app?+
A website presents information (like a digital brochure). A web app is fully-fledged software in the browser: with login, data processing, workflows, and user interaction. Think Trello, Notion, Figma, all web apps. If your users need to do something (not just read), you need a web app.
What does a web platform cost?+
An internal tool or dashboard starts at around €25,000–50,000. A full SaaS platform with multi-tenancy, billing, and user management typically ranges from €50,000–150,000. The price depends on complexity, integrations, and scaling requirements. After an initial conversation, we provide a transparent proposal with a phased plan.
Why React and not Angular or Vue?+
React has the largest ecosystem, the most active community, and the strongest hiring pool. Next.js as a meta-framework provides Server-Side Rendering (crucial for SEO and performance) and an excellent developer experience. We also work with Vue.js, especially in combination with Shopware 6. Technology choices are always made project-by-project, never dogmatically.
Can you modernize existing systems?+
Yes. We analyze your existing architecture, identify technical debt, and develop a migration strategy: incremental modernization (Strangler Fig Pattern) or a full rebuild with data migration. Our recommendation is based on an honest cost-benefit analysis, not on what brings us the largest contract.
How do you ensure security and data protection?+
OWASP-compliant development, regular penetration tests, encrypted data transmission (TLS), secure authentication (OAuth 2.0 / Auth0), and GDPR-compliant data processing. Hosting in German/European data centers. We can also support you with ISO 27001 and SOC 2 compliance if required.
