Summary
Matt Cortland, founder of an AI startup, created an AI agent named Rachel to track the price of a pint of Guinness across Ireland. Using data from over 3,000 phone calls, Cortland created the “Guinndex,” a consumer price index for Guinness. The Guinndex allows bartenders and beer drinkers to contribute and modify prices. The average price of a pint of Guinness in Ireland is around €6.01. Cortland hopes to replicate the success of the Guinndex for other products.

The numbers tell one story.
Matt Cortland’s AI agent Rachel made over 3,000 calls to pubs in Ireland to track the price of Guinness. The Guinndex shows the average price of a pint of Guinness is around €6.01. Cortland hopes to use the Guinndex to bring transparency to the market. He’s already seen some pubs lower their prices after being listed on the Guinndex.
The announcement sounds familiar: a small problem, a clever solution, and a potential for bigger applications.
Transparency is essential in a market where prices fluctuate wildly.
