Summary

Google has become the preferred AI partner for US marketing agencies, surpassing Adobe, Anthropic, Microsoft, and OpenAI for the first time since 2024, according to new Forrester and 4As research. This shift indicates agencies are now prioritizing comprehensive AI ecosystems that unify data, creative, media, and commerce, rather than solely focusing on individual AI models. Google's strength lies in its broad integration, connecting tools like Google Analytics 360, Meridian, Asset Studio, and AI models such as Gemini, Imagen, and Veo, with activation channels like Search, YouTube, and Display. This enables agencies to orchestrate end-to-end marketing workflows. Competitors are also evolving: Adobe is expanding beyond creative, Anthropic emphasizes trust, Microsoft seeks CMO relevance, and OpenAI faces the challenge of avoiding infrastructure dependence.

Key takeaway

For marketing executives evaluating AI partnerships, recognize that the market has shifted from individual models to integrated ecosystems. You should prioritize partners offering comprehensive platforms that unify data, creative, media, and commerce to orchestrate end-to-end marketing workflows. Avoid rigid, closed systems and instead seek interoperable solutions that provide flexibility and prevent vendor lock-in, ensuring your strategy remains customer-centric.
