What Hauptsache.net does

Hauptsache.net GmbH is a Hamburg-based web development agency founded in 1999 that builds custom TYPO3 CMS and Symfony PHP applications for German and international B2B clients. The firm operates as a professional services company rather than a product vendor, with a core team of nine people covering developers, front-end developers, a system architect, a copywriter, project managers, and a UX/UI designer. Its service portfolio spans TYPO3 implementations (including TYPO3 Headless with Next.js frontends), PHP/Symfony custom application development on AWS Lambda serverless architectures, e-commerce platforms, technical architecture consulting, UX/UI design, API and ERP/WMS integration, and AI-assisted content workflows anchored by the firm's own open-source TYPO3 MCP Server Extension.

The company monetizes through project-based custom development contracts, supplemented by recurring administration and maintenance agreements and non-exclusive hosting resold via Mittwald CM Service (servers in Germany). All engagements are individually scoped and quoted, with multi-year contracts typical and no public pricing disclosed. Go-to-market is direct enterprise sales initiated via project inquiry, targeting organizations with complex content, e-commerce, member-management, or integration needs. Notable long-tenured clients include Electronic Arts (direct partnership since 2022, subcontractor since 2008), Ad Alliance / Gruner+Jahr / RTL Deutschland (since 2001), Commerzbank, Menke Industrieverpackungen (since 2003), Fieberitz (~20 years), Michael Balint Institut (since 2019), Akademie der Wissenschaften in Hamburg, Tutti Fagotti, and Leibniz-IPN (FaBiUs).

The firm also publishes two open-source TYPO3 extensions: the TYPO3 MCP Server Extension (released 2025), which exposes TYPO3 content operations to AI assistants such as Claude through the Workspace system, and the TYPO3 Video Extension v2 (2024), which performs browser-side video compression to 720p h264 MP4 via WebAssembly ffmpeg. Hauptsache.net is privately held by founder and Managing Director Alexander Bernhardt, has no external investors, and operates as a registered German GmbH from Neuer Pferdemarkt 1, Hamburg.

Core offering

Hauptsache.net is a Hamburg-based B2B web development agency that builds, optimizes, and integrates custom TYPO3 CMS websites, Symfony-based PHP applications, custom e-commerce platforms, and API/integration solutions for enterprise clients. The firm also develops proprietary open-source TYPO3 extensions (TYPO3 MCP Server Extension and TYPO3 Video Extension) and provides ongoing maintenance, hosting, and AI-powered workflow services.

Product overview

Hauptsache.net is a Hamburg-based web development agency founded in 1999 that operates as a services firm rather than a SaaS company. Its portfolio consists of seven core service lines: TYPO3 website development (including TYPO3 Headless with Next.js frontends), PHP/Symfony custom application development (including serverless AWS Lambda implementations), e-commerce and shop development, system architecture and technical consulting, UX/UI design, AI-powered workflows (anchored by the TYPO3 MCP Server Extension), and API/integration development. Two extensions are offered as standalone open-source products: the TYPO3 MCP Server Extension (enabling Claude Code to interact with TYPO3 via the Model Context Protocol) and the TYPO3 Video Extension (for client-side video compression and management). Web hosting is also provided using Mittwald as the underlying infrastructure provider.
