Our Process

Measurable success
in 5 steps.

01

Discovery & Architecture

We analyze your requirements, choose the optimal tech stack (Next.js, Node.js, Supabase) and design a scalable system architecture.

02

UX/UI Design Phase

Before we write a single line of code, we visualize the user experience. Wireframes, prototypes and high-fidelity designs ensure clarity.

03

Agile Development

We develop in short sprints with regular updates. You see progress live and can give feedback early.

04

Quality Assurance

Automated tests, code reviews and performance audits ensure your application runs error-free and blazing fast.

05

Deployment & Scaling

We bring your application live (Vercel/AWS) and provide necessary monitoring to keep it stable even with high user numbers.

Your Benefits

We think in ROAS,
not in clicks.

Our clients don't choose colorful slides, they choose a team that understands marketing as an investment. We think in results, plan with clear goals, and deliver transparently.

Frequently Asked Questions (FAQ)

We work transparently. Here are answers to the most important questions.

We primarily use Next.js, React, TypeScript and Tailwind CSS. For databases we use Supabase (PostgreSQL) and for CMS solutions headless systems like Sanity or Strapi.
That depends heavily on the scope. A corporate website takes approx. 4-8 weeks, more complex web apps or e-commerce solutions 3-6 months.
We set up hosting infrastructures (mostly Vercel or AWS) that run in your name. We take care of setup, maintenance and scaling.
Our projects typically start from €10,000. For complex web apps or shops we are usually between €25,000 and €50,000.
