We Are openfellas

Specialists in ERP Implementation

Based in Munich, openfellas was founded in 2010 by the two IT specialists Ronald Hanke and Kristofer Eriksson. During their previous joint IT projects, they soon recognized the comprehensive advantages Open Source systems have to offer and wanted to utilize them for the benefit of other companies. Today, openfellas is a rapidly growing and successful company with 24 team members – including project managers, technical software designers, developers and support staff working in, by now, 3 locations – Munich, Heidelberg and Belgrade. In customer projects, our highly motivated professionals combine an in-depth technical knowledge of information technology with a comprehensive understanding of company processes. Following several successfully implemented ERP projects, openfellas was appointed Gold Partner by odoo in 2014 – and the desire to continuously help develop other companies still remains strong.

Let us be your personal Gold Partner and let us contribute, with a high-performance business software, to your company’s success story.

Ronald Hanke

Ronald Hanke is one of the founders of openfellas. He discovered his affinity for Open Source Applications during the founding of Zoiros in 2004. Within only a few weeks, he and Kristofer Eriksson developed the Lead Management and Call Tracking Software SmartChains, based on their experience in various Open Source projects. This in-house development was subsequently converted into a separate module for OpenERP. Ronald had discovered OpenERP, now Odoo, already in 2008, while he was looking for a flexible Open ERP system for Zoiros. At openfellas, he is responsible for sales as well as for the strategic alignment and future development of the business. In addition to his native language, German, he speaks fluent English and French.


Kristofer Eriksson

Kristofer Eriksson is the other co-founder of openfellas. He is one of the Open Source pioneers and significantly contributes to the openfellas know-how. Over many years, he has gained comprehensive knowledge and has proven his expertise as an architect and designer of complex, integrative solutions in many different projects for IBM, the Bankenverlag, Telekom and the Hypovereinsbank. Thanks to his experience we have succeeded in building an experienced technical team. At openfellas, he is responsible for project management and software architecture. Born in Sweden, he speaks fluent English and German, albeit with a slight accent reminiscent of the IKEA commercials, or so he claims himself.
