London-based AI engineer and entrepreneur Matthew Cortland gained international recognition for creating the Guinndex, a "living" consumer price index for Guinness in Ireland. To build the platform, Matthew developed Rachel, an AI voice agent powered by ElevenLabs and Twilio, which automated calls to over 3,000 Irish pubs in a single weekend. The Guinndex now functions as a real-time data hub, allowing both bartenders and consumers to contribute and modify local pint prices.

Prior to his work in AI-driven data and consultancy, Matthew was the Co-founder and CEO of The Cauldron. This venture, which launched in London, became a global success by blending technology with hospitality to create immersive, fantasy & Harry Potter-themed cocktail-making experiences. Today, he focuses on leveraging generative AI and automation to solve complex problems and create unique consumer-facing solutions.
