The document summarizes the results of the Apollon pilot project evaluating the use of living lab networks for testing homecare and independent living services across borders. The pilot involved transferring three such services between four living labs in different countries. A key finding was that a common cross-border ecosystem model for living labs in healthcare was not feasible due to differences between countries in areas like value networks, organization of healthcare, regulations, and infrastructure. However, living labs could still effectively serve as brokers and matchmakers to enable cross-border collaboration by addressing issues around stakeholders, access to users, liability, ethics, rules, and safety. Based on this pilot, the document advocates for a domain-specific network of smart care living labs to facilitate knowledge
