    What firms are best at marketing analytics?

    Updated October 21, 2026

    Key takeaway

    There is no agreed ranking of the best marketing analytics firms. Nielsen is named by ChatGPT, Copilot, Gemini and Google AI Mode, InfoTrust leads for Gemini and Google AI Mode, and Analytic Partners leads for ChatGPT and Google AI Mode. The engines say the best firm depends on the need, such as marketing mix modeling, attribution, data governance or enterprise implementation, and they group firms by those strengths.

    Mostly agree

    Nielsen is a leading marketing analytics firm

    InfoTrust is a premier choice for enterprise digital analytics

    Analytic Partners is strong for marketing mix modeling and ROI measurement

    Accenture suits enterprises needing managed analytics and implementation

    Where they differ

    Which kind of firm leads

      Verdict

      The engines do not agree on one answer, because each backs a different set of firms. Analytic Partners and Merkle appear in ChatGPT and Google AI Mode, while Copilot and Gemini name almost entirely different firms.

      The “best” marketing analytics firm depends on what you need: marketing mix modeling (MMM), customer analytics, attribution, digital analytics, experimentation, or a broader marketing transformation.

      When looking for the "best" firms in marketing analytics, the right choice depends heavily on your company's size, whether you need specialized B2B go-to-market infrastructure, enterprise-grade data governance, or consumer research insights.

      Leading firms and consultancies in marketing analytics fall into several distinct categories:

      1. Specialized Analytics & Data Consultancies (Best for Mid-Market & Enterprise Setup)

      2. Fractional GTM & Growth Analytics (Best for Scale-ups & B2B)

      3. Global Market Research & Consumer Insights Giants (Best for Brand & Media Mix Modeling)

      What to Look for When Choosing a Firm

      • Data Stack Alignment: Ensure the firm has deep experience with your specific stack (e.g., Google Marketing Platform, Snowflake, HubSpot, Salesforce, or custom data warehouses).

      • Attribution Capability: Many agencies manage media , but true analytics firms specialize in attribution - helping you solve multi-touch attribution (MTA) and privacy-first data collection challenges.

      • Execution vs. Advisory: Determine whether you need strategists to hand you a slide deck of recommendations, or hands-on operators who will actively write code, configure event tracking, and build your dashboards. The 7 Best Marketing Analytics Agencies for B2B in 2026 - GTM 8020
