What Plus B does

Plus B (plus B GmbH) is a Berlin-based digital agency founded in 2004 that delivers end-to-end web, app, and digital consulting services with deep specialization in the TYPO3 content management system. The firm operates from a single headquarters in Berlin, employs approximately 12 core experts supplemented by experienced freelancers, and is led by founder and Managing Director Robert Becker. Across more than two decades Plus B has completed over 600 projects for roughly 147 customers with a 5.3-year average retention, and has accumulated 112 team-years of TYPO3 experience and 156,372 lines of TypoScript. The company's customer base is concentrated in Germany and spans mid-market companies, federal and Berlin government agencies, NGOs and non-profits, and partner digital agencies.

Core offerings are organized around TYPO3 CMS as the technical backbone, with adjacent service lines in AI-powered chatbots (built on Ollama, Haystack, and RAG), browser-based 3D visualization and product configurators (Three.js with CAD-to-gltf via partner SEQUENZ), native and hybrid mobile app development, e-commerce implementation on Shopware, and specialized advisory in web accessibility (BITV 2.0, WCAG 2.1, BFSG), Green IT consulting, and IT security. Productized service packages — most visibly the tiered TYPO3 Update Service (€899, €1,899, €3,499) — sit alongside predominantly project-based custom development billed through phased concept/implementation/publication milestones.

The business model is professional services with a thin layer of recurring revenue from maintenance packages and select support relationships. The go-to-market is sales-led, driven by direct engagement via the website and senior contacts (Robert Becker, Alex Hänel), supplemented by community-led demand generation through TYPO3 BarCamp participation (34 events) and Silver Membership in the TYPO3 Association since 2011. Notable customers include Berlin Partner für Wirtschaft und Technologie, the Bundesministerium für Landwirtschaft (BMEL), DAB Digitalagentur Berlin, BerlinOnline, the Unabhängige Beauftragte für Fragen des sexuellen Kindesmissbrauchs, Numerik Jena, Albatros gGmbH, and Literarisches Colloquium Berlin. The firm is privately held, bootstrap-funded, and operates with no external investors or parent company.
