B Capital is a venture capital fund founded by Facebook co-founder Eduardo Saverin that operates with a formal strategic partnership with Boston Consulting Group, giving portfolio companies structured access to BCG's clients and consulting expertise rather than typical loose value-add networks. The firm uses a deliberately global "one firm" model where the same partners can lead deals across the US, Europe, and Asia in sectors like enterprise software or cybersecurity, combined with an institutionalized four-pillar operating platform for systematized post-investment support.
