The Challenge
Noble People, an advertising agency, faced a persistent challenge that CMOs across the industry share: determining the right budget split between brand-building and performance media — and then convincingly pitching that allocation to their CFO. Without a rigorous, evidence-backed rationale, brand marketing budgets were routinely undercut because they lack a direct correlation to sales. Marketers were spending excessive time preparing budget presentations, often from a blank page, with no structured framework to defend their decisions.
What They Built
Stoop Studios built Budget Balancer — an interactive web tool that uses a GPT-4o Assistant to calculate the optimal brand vs. performance media split grounded in the Binet and Field academic frameworks, then connects users to a voice-enabled virtual CFO via OpenAI's Realtime API for pitch practice.
Stoop Studios began by encoding the Binet and Field academic frameworks as structured knowledge within the GPT-4o Assistant context — giving the tool a principled foundation rather than relying on general AI reasoning about budgets. Users input details about their brand, category, and goals; the assistant synthesizes those inputs against the frameworks and produces a personalized brand vs. performance split recommendation, complete with a written rationale designed to hold up in a CFO conversation. The second stage addresses execution of that recommendation: a role-play mode connects the user to a voice-enabled virtual CFO powered by OpenAI's Realtime API. The CFO pushes back, asks hard questions, and lets the marketer stress-test their argument before the real meeting. The front end was built in Next.js and deployed on Vercel. Total build time was approximately three to four weeks. The result was a tool that compresses days of manual budget preparation to minutes — and converts a typically anxious budget defense experience into structured practice.
AI Role
The voice-enabled CFO simulation gives marketers a live practice environment to stress-test and refine their pitch — a capability previously impossible to replicate without live role-play partners or coaching.
Infrastructure
• Next.js (front-end framework) • OpenAI GPT-4o Assistants API (budget recommendation engine) • OpenAI Realtime API (voice-enabled virtual CFO) • Vercel (deployment)
Integration Points
• GPT-4o Assistant configured with Binet and Field framework knowledge for budget synthesis • User input form connected to Assistant API for personalized recommendation generation • Realtime API voice session triggered from recommendation output for CFO role-play • Next.js front end deployed on Vercel with API route handling for both OpenAI endpoints
Best for advertising, media, and creative agencies — and brand-side marketing teams — that need to justify brand marketing investments to finance leadership but lack a structured, evidence-backed process for determining and presenting budget allocations.
