Team Size: Solo founders and freelancers will find Novo sufficient. Small teams of 2-10 should use Relay for its multi-account organization. Growing teams of 10-50 should use Mercury for its multi-user access and integrations. Teams of 50+ should consider Brex for its expense management and corporate card program.
