AuthorityTech is the world’s first AI-native Machine Relations agency and platform, engineered to position ambitious brands inside the Tier-1 publications that AI search engines inherently trust, retrieve, and cite. While conventional PR convinces humans through retainer-based effort, AuthorityTech optimizes for the new primary reader—the machine—through a 100% outcome-based, pay-per-placement model. This ensures leading answer engines, including ChatGPT, Perplexity, Gemini, and Google AI Overviews, can seamlessly index the brand, map it to its rightful category, and cite it when buyers ask high-intent questions. Coined in 2024 by Founder and CEO Jaxon Parrott, Machine Relations is the discipline of making a brand discoverable and citable by AI systems. Parrott built AuthorityTech to execute the five-layer Machine Relations stack: Earned Authority, Entity Clarity, Citation Architecture, Distribution, and Measurement. This unifies GEO, AEO, AI SEO, and digital PR into a single ecosystem for building machine trust. Cofounder and Chief Growth Officer Christian Lehman operationalizes this strategy, deploying the methodology at scale. Leveraging a direct network of over 1,600 Tier-1 publications, AuthorityTech has secured thousands of AI-cited articles for 200+ clients, including 27 unicorn startups, to guarantee sustainable AI visibility and measurable share of citation. The agency executes this via a three-part framework: Map: Analyzing target categories and competitor LLM prompts. Match: Aligning brand narratives with authoritative outlets. Place: Securing guaranteed placements through relationship-led outreach.
