Built on a Claude MCP agent pulling brand and ICP context from Airtable, with an n8n workflow handling routing and logging. Strategic Angle Dogfooding proof: the AI-native GTM engineering I sell, running on my own business. Content is a systems problem, not a content problem. Best Used For - AI-native GTM and GTM-engineering positioning - Automation and cost-efficiency proof - Founder-led operations - The "engineer your growth system" thesis The System Context LayerBrand, ICP, and offer context held in Airtable as the single source of truth. Agent LayerA Claude MCP agent drafts on-brand content against that context on demand. Routing LayerAn n8n workflow routes, logs, and publishes, leaving review as the only human step.
