This study proposes a hybrid model of initial trust formation that highlights the role of social categorization and its interplay with both institutional trust and the individuating information about the party. Using data on 1,474 corporate venture capital (CVC) investments in European ventures and a case-control research design, we find that ventures more likely form initial CVC ties with investors whose parent companies are located in countries considered more trustworthy. This effect is weaker but does not disappear when social defenses safeguard ventures from misplacing trust and when there are social ties between CVC investors and ventures’ independent VC investors.
