West Cary Group, a Richmond-based advertising agency focused on marketing, data, and technology, has completed the sale of its proprietary Generative Pre-Trained Transformer (GPT) to a major global digital transformation company. The deal marks one of the first public sales of a custom GPT developed by an agency, signaling a new chapter in applied AI adoption.

The Marketing Research GPT is designed to accelerate strategic marketing tasks such as competitor mapping, trend analysis, audience profiling, and go-to-market planning—functions critical for data-driven marketing teams.

The tool has seen strong adoption, ranking as the second most-used research GPT on OpenAI’s ChatGPT platform for eight consecutive months. It was also spotlighted in OpenAI’s curated GPT recommendations, a rare nod that underscores its effectiveness.

“Large language models have unlocked a significant new market for our firm,” said Moses Foster, president and CEO of West Cary Group. “This sale validates our strategy of becoming a dedicated GPT provider for industries we know best, including financial services, energy, healthcare, and the public sector.”

Mike Benjamin, the tool’s lead creator, added: “Our goal was to architect a solution that addresses specific challenges for marketers. The acquisition by a market leader confirms we’ve developed a truly effective and valuable tool.”

The transaction positions West Cary Group as an early mover in the commercialization of industry-specific AI, with plans to expand into additional enterprise-grade solutions.
