Digital marketing agencies are uniquely positioned to benefit from AI. As an industry built on margins, headcount, and intellectual property, the transition from SaaS to "Service-as-Software" via internal agents is inevitable.

Infinite Scalability: Servicing 100 accounts with the team size previously required for 20.
