Castle Island Ventures

We are a venture capital firm focused exclusively on public blockchains. We invest in infrastructure and application companies that will enable these transformative protocols to power services for the next billion users.

We believe that permissionless blockchains represent a new form of politico-economic institution that will fundamentally alter market structures and spawn entirely new industries. 

We are focused on supporting entrepreneurs who are on a mission to build the infrastructure services to push these networks to their potential.
