The Problem
Performance marketers spend hours building reports and analyzing data across platforms. Static dashboards and reports help with recurring data visibility, but getting ad hoc real-time insights from Google & Meta Ads and Google Analytics requires lots of manual work and context switching.
The Insight
Aditya Sriram saw performance marketing changing rapidly due to evolving algorithms and AI capabilities. So he and his co-founders built an MCP server at GoMarble that turns LLMs into real-time performance marketing analysts.
How It Works
GoMarble's MCP (Model Context Protocol) server acts as an interpreter that enables LLMs like Claude to access live data from your ad accounts. You can:
Pull real-time performance data from Google Ads, Meta Ads, and Google Analytics
Generate detailed ad hoc performance reports in minutes instead of hours
Conduct ad hoc analysis like time-bound root cause analysis of performance dips and spikes by asking natural language questions
The tool essentially makes Claude a data-connected analyst that can answer questions like "Why did my Meta spend spike yesterday?" or "Show me campaign performance trends for the last 30 days" with actual numbers, not hallucinated data.
What's Accurate vs. What Requires Human Judgment
The data recall is highly accurate because the LLM works with real numbers from APIs. However, ambiguities can arise if prompts are vague or metrics have multiple definitions.
For reasoning and recommendations, the tool provides powerful hypotheses based on data trends, but human expertise remains crucial. The LLM can spot patterns and suggest potential causes, but it can't replace the account context and strategic judgment that experienced marketers bring to decision-making.
What's Coming Next
Aditya says GoMarble will be rolling out its own platform, removing it’s current dependency on the Claude UI. They’re also adding more sophisticated capabilities and connectors to deepen creative analysis and streamline performance workflows including visual video/static ad analysis that allows the AI to break down what’s working and what could improve in your creative, along with competitor research tools to help you stay on top of the ad angles your peer brands are using. Expanded custom reporting features and support for new connectors like Shopify, TikTok Ads, LinkedIn Ads, and more are also on the way.
Business Model & Access
Basic connectors for Google Ads, Meta Ads, and Google Analytics will stay free. Advanced features like AI driven creative analysis, competitor research and more powerful reporting capabilities will be part of a paid tier with a dedicated interface optimized for growth marketers.
The Bottom Line
GoMarble represents a shift toward AI-powered performance marketing analysis that works with real data, not assumptions. The team serves 15 partners with full-stack performance marketing services while powering 2,000+ users with their MCP tool. They also have an active 600+ member Slack community for support and prompt sharing.
