Framework: Healthcare project finance (PF) involves long-term structural investments in hospitals, typically within a public–private partnership (PPP). Banks represent the third major stakeholder, supporting the private player. Within this well-known framework, digital platforms represent a new virtual stakeholder, operating as a bridging node that incorporates information, and eases transactions. The relationships among the stakeholders are re-engineered around the platform and may be expressed with network theory patterns, even considering its multilayer extensions. Justification: As these investments are highly leveraged, especially during the construction phase, bankability represents a major sustainability concern. Objective: The research question is focused on the savings deriving from the introduction of networked digital platforms, and on their impact on bankability, shaping a new PPP model. Methodology: The study is conducted through (a) an economic–financial sensitivity analysis where digital savings impact on key PF parameters, including bankability; (b) a mathematical interpretation, based on network theory, where the stakeholders of two ecosystems—respectively, without and with a digital platform—are compared. Results: The creation of a value-adding “pie” anticipates its partitioning among the value co-creating stakeholders. This study represents an advance in the field, showing how technological innovation may improve the overall bankability and the value creation of leveraged infrastructural investments, even beyond the healthcare industry.
