Gartner’s warning isn’t anti‑AI—it’s anti‑dependency. The distinction will define which agencies remain relevant by the end of the decade.
A recent Gartner study predicts open-source platforms will support more than 75% of enterprise AI deployments by 2028, and their concern about CMOs getting locked into agency-controlled infrastructure is legitimate. Their concerns deserve to be taken seriously, but their analysis describes a specific type of platform — one owned and operated by the agency, bundled into retainers, sitting on top of client data with the client as a passenger.
In other words, Gartner isn’t warning against agencies using AI. They’re warning against enterprises outsourcing ownership of their AI operating model.
That’s not what we built at EVERSANA. And the distinction matters enormously.
The core Gartner risk: dependency on someone else’s platform
The concern Gartner raises is that a CMO who embeds with a a large holding company is “likely to get disintermediated” from enterprise-wide AI strategy discussions led by the CIO. When the agency owns the platform, the client owns nothing. If the agency relationship ends, the infrastructure — and often the institutional knowledge baked into it — walks out the door with them.
This is the structural risk Gartner is calling out: speed and scale today, fragility tomorrow.
The holding companies are converging on the same vocabulary, the same AI layers, the same agentic orchestration — and clients are increasingly aware that this convergence doesn’t serve them. It serves the agency’s efficiency and margin, but not the client’s long‑term enterprise capability.
Our model inverts this entirely
Our platform, developed in partnership with Google Cloud, is designed to be adopted by the client and built upon — not rented from us. The client owns the environment, the data, the workflows, and the institutional memory. We provide the infrastructure and the expertise to stand it up; they build equity in it over time.
We made a deliberate choice to align with Google Cloud because AI is no longer a marketing feature—it is becoming core enterprise infrastructure, and it must meet the security, governance, and evolution standards expected by CIOs, not just CMOs.
This directly addresses every concern Gartner raises:
- Portability: Clients aren’t locked to us. The platform is theirs to take, extend, or migrate.
- Data sovereignty: Nothing is siloed inside an agency retainer. The client’s data stays secure with the client.
- Pluggable intelligence layer: AI is evolving fast and we account for the unknowns. It’s hard for any company, especially large corporations, to shift the AI models and agentic architecture at the speed of change. Our platform allows “plugging-in” and testing new models and agents that we call the “intelligence layer”.
- Composability: Gartner specifically recommends a “composable” AI strategy — using agency platforms selectively while retaining ownership of data, models and governance. That’s precisely the architecture we provide.
- CIO alignment: Because our platform is designed as enterprise infrastructure — not a marketing point tool — it’s built for the conversations happening at the CIO and CDO level, not just the CMO.
What Gartner’s warning actually validates
The large holding companies are converging on a vision of agencies as managed ecosystems of AI agents, built on proprietary data, wrapped in compliance, and plugged into end-to-end marketing execution. That’s a platform you use. We’re offering something different: a platform you own.
This “use vs. own” distinction is the real fault line Gartner’s forecast exposes.
Gartner is right that half of today’s proprietary agency AI platforms may be obsolete by 2029. The ones that will survive — and thrive — are the ones where value accrues to the client, not just the vendor. The agencies that endure the AI transition won’t be the ones that control the most technology. They’ll be the ones willing to help clients own it.
We built for that future from day one.
