Purpose: Although previous research has highlighted the importance of innovative intermediary services that are delivered through cluster initiatives to foster own attractiveness and the development of business, little emphasis has been placed on examining the patterns and influencers of such a change in new organisational forms from a management perspective. The present study investigates the change patterns of core intermediary activities in cluster initiatives as well as the influence of various stakeholders on change in those core activities. Design/methodology/approach: The empirical data of this work illustrates the general picture of change within new organisational forms and therefore emerges from a survey study carried out among numerous European cluster initiatives originating from different industries. The main propositions for testing have roots in and are discussed through the prism of Stakeholder Theory as well as entrepreneurship, change and intermediary (middle-hands, brokerage) literature. Findings: The findings reveal that intermediary activities are under continuous change, and the changes appreciated by the initiative members tend to gradually increase in intensity over time. Internal stakeholders are actively engaged in the change process activities, and external stakeholders are too, but to a limited extent. This leaves space for creativity and action for the initiatives. Research limitations/implications: This research combines stakeholder theory and literature on intermediation (new forms of organisations), change, and entrepreneurship. The outcome of the study might serve as a ground for theoretical classification of cluster initiatives as a particular type of intermediary in accordance with their specific occupation. This would add to the ongoing discussion on definition and typologies of intermediaries as well as lift the awareness on the peculiar constellation of stakeholders within these innovative organisations – their engagement expectations and level of involvement. Practical implications: Knowledge on which stakeholders can turn to in the event that a special service is needed can shorten implementation times and improve the quality of services. This knowledge is a way to choose suitable and influential networking partners who can assist by pushing existing working mechanisms in a favourable direction. Social implications: The study illustrates the patterns behind changes of intermediary activities/services over time, which would form solid ground for developing new methods to assist in achieving stakeholder satisfaction through cluster-initiative services. Therefore, this work can serve as a benchmarking example for traditional organisations that find themselves in “sleeping” mode or that aim for revitalization. Originality/value: The contribution of change and engagement mechanisms to effectivization and innovativeness of organisations are highlighted as main value added of this research. © 2020, Emerald Publishing Limited.
