Performance marketing agency — 12 client accounts · in production

A multi-agent advertising operating system

Challenge

Twelve advertising accounts across Google, Meta and TikTok, each with its own tracking, budget and rules — and one person to watch all of them. Silent failures (delivery stopped, tracking on consent, geo leaks) were found weeks late.

System

One brain per account (281 governed tools), twelve agency-core agents (health, incidents, analysis, strategy, alerts, prompts, competitive and creative intelligence), daily sync into an owned database, a read-only 15-rule weekly check with evidence, Excel reporting to Drive, and a decision log where every change is proposed, approved, executed once, measured and reversible.

Technology

Result

• 24 workers live, 5 scheduled automations, 12 accounts synced daily
• A lead event firing on cookie acceptance found and fixed: ~1,900 "leads" of which ~180 were real
• Weekly check proven read-only by structural tests
