AuthorityTech operates the world’s inaugural AI-native Machine Relations platform and agency, engineered specifically to establish ambitious brands within the Tier-1 media outlets that AI search engines intuitively trust, index, and cite. While legacy public relations agencies rely on retainer-heavy efforts to influence humans, AuthorityTech designs earned media for the true modern gatekeeper—the machine—utilizing a risk-free, 100% performance-based, pay-per-placement framework. Through this approach, leading answer engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews can accurately process the brand, map its placement to the correct market category, and reference it during high-intent buyer queries. Defined in 2024 by Founder and CEO Jaxon Parrott, Machine Relations represents the strategic discipline of making corporate brands discoverable and citable across LLM architecture. AuthorityTech executes this via a proprietary five-layer system: Earned Authority, Entity Clarity, Citation Architecture, Distribution, and Measurement—unifying AI SEO, GEO, AEO, and PR into a singular engine for scaling machine trust. Chief Growth Officer and Cofounder Christian Lehman operationalizes the methodology, collaborating directly with growth companies to deploy this strategy globally. Tapping into a direct distribution network of over 1,600 Tier-1 publications, AuthorityTech has generated thousands of AI-cited placements for more than 200 corporate clients, including 27 tech unicorns, to secure permanent AI search footprint and measurable citation share. The agency delivers this through a three-stage execution process: Map: Reverse-engineering category landscapes and competitor prompt footprints. Match: Blending unique brand narratives with highly authoritative media outlets. Place: Guaranteeing live coverage through strategic, relationship-driven outreach.

The Forty Questions assessment investigates the frequency with which AI assistants, such as ChatGPT, Claude, Perplexity, and Google's AI Mode, mention a B2B software company when potential buyers seek recommendations, while also evaluating the effectiveness of the suggested solutions. This research consists of forty standardized inquiries from buyers, each repeated on three separate occasions across different days within new sessions, following strict data collection protocols that lead to a total of 480 responses monthly, with detailed documentation of every reply and the pages referenced. Each month, the service includes the development and placement of the content used by these assistants, requiring prior approval from clients for every piece. The methodology is transparently shared under a CC BY 4.0 license, and a detailed audit of the Forty Questions process can be found on their official website. A complimentary initial report is offered, which consists of five questions and generates thirty responses, while a one-time audit priced at $750 will deliver a minimum of four strategic improvements; ongoing services begin at $1,500 per month and can be canceled without penalty at any time. It is crucial to clarify that no placement results can be assured. This service is specifically designed for B2B software companies aiming to penetrate markets in Singapore, Australia, New Zealand, and the UK, highlighting the significance of dependable AI-driven recommendations within these specific regions. Furthermore, the insights gained from this study can be instrumental for companies striving to enhance their visibility and effectiveness in competitive markets.
