What haj.tech does

haj.tech GmbH is an owner-managed, full-service digital agency headquartered in Kiel, Germany (Holtenauer Str. 231). The firm delivers bespoke web development, custom web applications, e-commerce platforms (Magento and Shopify), and digital marketing services — SEO, SEA (Google Ads), and web analytics — together with strategy consulting and AI integration. Its technical foundation centers on the open-source SilverStripe CMS (PHP/MySQL with Symfony MVC framework), complemented by React on the frontend, GraphQL APIs, OAuth 2 authentication, NGINX on Linux, and Progressive Web Apps (PWA) as the delivery vehicle for several client platforms. A notable proprietary layer is the firm's self-developed AI modules embedded directly in SilverStripe CMS, enabling one-click content creation, multilingual translation, image caption/alt-text generation, and SEO entry generation without leaving the CMS workflow.

The agency operates with a small, flat-hierarchy family team (1–10 employees), drawing on 25+ years of operating history through successive corporate identities — from the web unit of vertikal! Werbeagentur GmbH (1996) to E-Formation GmbH (1999), ennit AG/ennit interactive GmbH (2012), and the 2022 rebrand to haj.tech (with parallel entity haj.swiss covering the Swiss market). Revenue is generated primarily through project-based engagements (custom web builds, web applications, e-commerce implementations, digital transformation projects) and recurring SEO/SEA retainer contracts. The agency serves mid-market and enterprise clients across the DACH region (Germany, Austria, Switzerland) with deep specialization in the hospitality and hotel industry — including historical work for Kempinski (1998–2017), Romantik Hotels & Restaurants, Sunstar, Vitznauerhof, and Teufelhof Basel — alongside engagements in transportation (RDC Deutschland), e-commerce/retail (ORION Versand), real estate technology (smartconext SaaS), and non-profit/social services (Northern Society for Diakonia, 90 managed websites over 20+ years). The firm reports that 90% of its clients have been with the agency for many years, indicating low churn on the existing book of business despite the boutique scale.
