About Us

CRSTBL Inc. is a trailblazer in AI-powered business technology, founded in 2021 by James McMillian and John Chang to redefine marketing for everyday AI users.

Meet CRSTBL—AI with business experience. Our founding team pairs a technology leader with 20 years in AI software development alongside a business founder who built a $200M retail distribution system. This unique combination drives CRSTA-AIDX, the world’s first AI Discovery and Execution platform that bridges cutting-edge AI capabilities with proven business outcomes.

AI search isn’t about ranking or showing users a list of blue links—it’s about understanding consumer intent. As more people use LLMs for search, brands need to adapt quickly. CRSTA-AIDX enables this transition by combining GEO with an execution engine powered by 1,000 neural networks that identify attributes, locations, and categories to decipher intent, personalize responses, and address the parts of the marketing funnel being flattened by LLMs.

Our Vision & Platform

CRSTBL’s CRSTA-AIDX platform represents the future of enterprise marketing and commerce.

The platform goes beyond traditional SEO and web strategies, offering a unified architecture built for AI agents — including ChatGPT, Alexa, Gemini, and emerging generative AI systems.

At its core, CRSTA-AIDX centralizes:

Semantic analysis
Structured data management
Campaign execution and optimization
Real-time performance insights

This allows brands to deliver contextually relevant, highly personalized experiences directly through AI-driven discovery and transaction channels.

By bridging marketing and machine understanding, CRSTBL is reimagining how products and services are surfaced, accessed, and purchased in an era where answer engines shape consumer choice and conversion.

Industry leaders

Research & Industry Insight CRSTBL’s independent research and content highlight the risks and opportunities brands face as AI answer engines replace traditional search results and “ten blue links.”
Our AI Discovery & Execution (AIDX) framework helps protect brands from misinformation, lost visibility, and revenue leakage. Findings from our recent white paper on The Hidden Costs of AI SEO Inaccuracy revealed that local businesses lose an estimated $20,000 to $250,000 annually due to incorrect data and poor AI visibility.
CRSTBL empowers businesses to future-proof their digital presence, guiding CMOs and marketing leaders through the transition from human-centric navigation to agent-mediated discovery, transactions, and proactive engagement.
