Development of pyswarm has been started at the HATZIS Edelstahlbearbeitung GmbH. HATZIS is a family-owned and med-sized steel-engineering company in Bavaria, Germany, which provides to more than 300 companies construction and production services for highest quality components made of stainless steel. The stable growth during the past years, and the measurements on behalf of new business fields, adviced the company to take a further step in its information technology usage.

Since the company's success heavily bases on highly customized solutions around stainless steel components, also the processes and requirements are too individual to be supported by standard software from the shelf. On the other hand individual software development was considered to be too expensive and risky. Thus model-driven software-development has been the approach of choice, enabling very individual applications in a short time and with low budget. Since it was hard to find a MDSD technology on the market, specialized for the team-work of Python and PostgreSQL, and Anastasios Hatzis brought some MDSD know-how into the company, so the decision has been made to start an open-source project under Free Software licenses. It became today's pyswarm project.

In January 2007 the Free Software Foundation Europe became legal guardian of the pyswarm project.
