Cofund is an enterprise-focused platform for policy-driven budget approvals. Different spending levels require different authorization expressions (e.g., an employee might need approval to spend $50 while C-suite executives can move $50K or more). These expressions answer two core questions: who can approve and how much can they move? These form the foundation of what Cofund calls "policies" - the crux of the platform's engineering. Multisigs are treated as a first-class primitive because business adaptability requires supporting coordinated hierarchical approvals. For organizations allocating budgets to teams, Cofund enables the fine-grained control needed for flexible approvals.
