Since January 2005, HA Hessen Agentur GmbH is the new one-stop address for non-monetary economic development in Hessen. The state-owned agency with 150 employees is responsible for efficient, transparent and customer-oriented economic development in Hessen.

The HA Hessen Agentur GmbH is carrying on the work of the former state-run institutions such as the Technology Foundation Hessen (TSH), Research and Development Company Hessen (FEH), Hessen Tourism Service (HTS) and the non-monetary economic promotion activities of the Investment Bank Hessen (IBH). However, the HA has also assumed new responsibilities from the state of Hessen in order to more closely link internal and cross-functional processes. At the same time, the Hessen Agency uses modern economic promotion and marketing tools to present Hessen as an attractive business location, both domestically and internationally.

HA’s Business Location Marketing department encompasses the economic promotion campaign ("Hessen >> That's Future"), European advisory services, business location services, international trade and tourism marketing. The business location marketing activities highlight Hessen's advantages over competing regions in Germany, Europe and overseas. The Hessen Agentur has a global network with representative offices in the USA, China, India, Japan and the United Arab Emirates. A number of different instruments are used to support Hessen-based businesses, including international trade fairs, market research, specialized congresses, as well as delegation and business trips.

The departments of Technology, Innovation and Education are focused on the following areas: media, information technology, biotechnology, nano-technology, environmental technology, technology transfer, clusters, model projects, and life-long learning. The media and IT expertise centres of the Hessen Agency as well as the state-wide initiatives “hessen-media”, “multimedia intiative hessen” and “hessen-it” all work to successfully position this sector on international markets.

The HA City Development (HA SEG) is a 100% subsidiary of the Hessen Agentur and performs a fiduciary function for property development projects. It is currently involved in major projects: Riedberg in Frankfurt am Main and Stadtallendorf in central Hessen.
