erdfisch GbR

erdfisch is a Drupal agency based in Heidelberg, Germany. We were founded in 2005 and have worked with Drupal exclusively ever since, which makes us one of the longest-standing Drupal specialists in the German-speaking market. Our clients run large and complex Drupal platforms: corporate websites, multisite networks, public sector portals and association platforms. Typical engagements are relaunches, migrations to current Drupal versions, multisite architectures, audits and long-term maintenance. Long-standing clients include Conductix-Wampfler, WERTGARANTIE, the German consumer advice centers (Verbraucherzentralen) and DLR Projekttraeger. We build our own tooling where standard solutions fall short. ULF automates the Drupal update lifecycle and keeps sites patched, tested and documented. Our Sites suite lets organizations operate entire multisite networks from one place and launch additional sites without a development project for each one. We stay involved well beyond go-live. Security, maintainability and digital sovereignty shape the way we build. Our managing director chairs Drupal e.V., the German Drupal association, and we contribute back to the open source community our work is built on.
