Platform Concentration Risk

Platform Concentration Risk is the exposure an agency carries when a client's paid media performance depends on one ad platform, one AI vendor, or one automation layer. The risk is not the platform itself but the absence of a tested fallback when it degrades. For agencies, this shows up as retainer volatility: a single API change, policy shift, or outage can stall delivery across every account at once. The framework asks operators to map each client's spend and workflow against the number of independent systems that could absorb a failure. A concrete trigger came when simultaneous outages hit ChatGPT, Claude, and Grok, leaving agencies with single-provider AI dependencies without fallback options, as reported by Zapier. Agencies running campaign automation through tools like Ryze, Nanos, or Plai should document which platform each client's budget concentrates in, and whether a manual or alternate path exists. Concentration is acceptable when it is measured and priced; it becomes a liability when it is invisible.
