Ad Agencies Are Embracing ‘Vibe Coding’ to Build GEO Products for Clients

Why It Matters

GEO tools let brands shape their presence in AI‑driven search, turning agency expertise into a scalable revenue stream while reducing reliance on expensive third‑party AI contracts.

Key Takeaways

• Agencies build GEO tools in hours using Claude Code.
• Havas' Brand Insights AI covers 100 countries, 60 languages.
• In‑house GEO solutions avoid costly enterprise AI licenses.
• Tools enable dynamic brand ranking across AI models and personas.
• Agency‑built GEO products become SaaS offerings and pitch assets.

Pulse Analysis

The rise of "vibe‑coding" signals a new development methodology for ad agencies, where generative AI models become the foundation of custom software rather than a mere service. By leveraging coding assistants like Claude Code, agencies can prototype and deploy GEO applications in a matter of hours, dramatically shortening the innovation cycle. This agility allows them to respond to client demands for brand visibility in AI‑generated answers, a capability that traditional SEO tools were never designed to address.

From a business perspective, in‑house GEO platforms provide agencies with both cost control and strategic differentiation. Instead of signing multi‑million‑dollar enterprise agreements with AI vendors, firms can license models on a pay‑as‑you‑go basis, tailoring usage to actual adoption rates across teams. The ability to simulate brand appearances across multiple LLMs and persona‑based queries equips marketers with granular competitive intelligence, turning data into a sellable service. Consequently, agencies are monetizing these tools as SaaS products, embedding them into pitch decks and winning new accounts.

Looking ahead, the integration of LLMs as core infrastructure suggests that agencies will evolve into software providers as much as creative shops. Continuous feedback loops—where models generate, evaluate, and refine content autonomously—promise higher efficiency and reduced human oversight. As AI‑driven discovery becomes the primary consumer research channel, agencies that master GEO will shape brand narratives at the algorithmic level, redefining the ad tech landscape and creating new profit centers beyond traditional media buying.
