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.

Vehicle Acquisition Network (VAN) is private-party vehicle acquisition software for franchise and independent auto dealerships. It helps dealers buy used cars directly from consumers in their local market, alongside trade-ins and instead of paying up at auction. VAN pulls for-sale-by-owner listings from 25+ online marketplaces into one dashboard, filters out dealer and scam listings and Do-Not-Call numbers, and adds VIN decoding and market valuation to each vehicle. Buyers call, text, and email sellers from inside VAN, and every conversation stays attached to the car it is about. On VAN Accelerate™, outreach and follow-up run automatically, KBB ICO leads get a text back within minutes, and AccuTrade leads get an automatic response. For dealers without a buyer on staff, VAN Managed Buyer™ supplies a full-time buyer who is hired, trained, and managed by VAN. The dealership still makes the final buy decision and signs the check. Every plan includes an Acquisition Coach™, and VAN works with vAuto, VINCUE, CARFAX, AutoCheck, and most dealer CRMs. VAN was founded in 2013 and serves dealers in the United States, Puerto Rico, and Canada. Plans start at $1,695 per month. To see VAN on your market, call 855-952-4949.
