This article discusses the question 'How is learning supported within innovation labs and what are its impeding factors?' It is based on three case studies already carried out on innovation labs in the social welfare sector in Germany. The use of innovation labs creates a specific setting for learning in the context of the workplace for its participants. The goal of the researched labs is to develop entrepreneurial education of the participating social intrapreneurs, which are mainly employees of different social enterprises. Participants are introduced to a combination of methods to foster social innovation through an open innovation process. The author points out three success factors for intrapreneurial learning, which are the lab process and methods used, the collaboration of the participants and the involvement of the organisations that sent their employees. The last chapters present the research results which are connected to the discourse of Adult and Continuing Education and strengthen the potential for organisations of continuing education as well as the need for research on integrated learning opportunities in the context of upcoming challenges in Germany.
