Pints, Petrol and Prices

Pints, Petrol and Prices

Author: Maryrose Lyons April 14, 2026 Duration: 23:21

The CSO stopped tracking the price of a pint of Guinness in Ireland in 2011. The last official figure was €3.93. Nobody picked it up again until Matt Cortland and John Fleming decided to call every pub in the country and ask.

Using Google Maps for contact data, 11 Labs to clone a Northern Irish voice, Claude Code to orchestrate the whole system, and Twilio to actually make the calls, they built the Guinndex: a real-time index of pint prices across Ireland and Northern Ireland. Over 700 pubs called. Total cost: approximately €200.

They didn't stop there. With fuel prices dominating headlines on both sides of the Atlantic, they applied the same methodology to US gas stations, creating the Gas Index, complete with AI agents named after King of the Hill characters and a feature that tells you whether the cheaper station is actually worth the drive.

This episode is a masterclass in what's possible when you connect off-the-shelf AI tools with a problem worth solving. And a cautionary tale about the Irish goodbye.

Maryrose Lyons brings her experience from the AI Institute to Chatting GPT, a podcast that digs into the practical realities of artificial intelligence. Instead of theoretical discussions, these are grounded conversations with the directors, founders, and strategists who are implementing AI solutions right now. You’ll hear from people who have moved their organizations beyond pilot projects into genuine transformation, sharing what worked, what didn’t, and why. The focus often lands on the built environment-exploring how AI is actively reshaping design processes, construction methodologies, and facility management from the studio to the job site. This series is built on the premise that the most valuable lessons come from those with hands-on experience. Each episode unpacks the human decisions behind the technology, offering tangible insights for professionals in technology, business, and education who are navigating their own courses. By listening to this podcast, you gain access to a rare dialogue about applied intelligence, where the conversation is always rooted in real-world execution and impact.
