twentyonepixels Verified Company

twentyonepixels is a small, owner-led software studio in Bietigheim-Bissingen, just north of Stuttgart. Behind the name is one developer, Alexander Seidler, who plans, builds and runs every project himself. Clients talk to the person who writes their code, from the first call to the day the system goes live and beyond.

Most of the work falls into three areas. First, web applications and custom business software built with Laravel, Vue.js and Inertia, typically replacing spreadsheets and manual processes that no longer scale. Second, fast marketing websites and landing pages with Next.js, React or Laravel, with structured data and local SEO built in rather than added later. Third, practical AI: chatbots and RAG knowledge bases that answer from a company's own documents, hosted in Germany and designed around the GDPR and the transparency duties of Article 50 of the EU AI Act.

A few examples show the range. For the TEAL. Festival in Heilbronn we built a Next.js site with an integrated ticket shop that is pre-rendered so ticket drops do not hit the application directly. For a patient transport service in Ingersheim we built a Laravel site whose request form captures trip type, date, pick-up and destination in a structured way. For a cafe we developed DIMO, a staff scheduling and time-tracking application with a role and permission system, audit trail and payroll exports; it is covered by 816 automated tests.

What we do not do: we are not a large agency with account managers, and we do not take on projects we cannot staff ourselves. We work for small and medium-sized businesses in Germany, Austria and Switzerland, in German or English.
