Twilio Voice and AI power innovative Guinness Price Index

Guinness Price Index creator to discuss the future of Voice AI and programmable communications at SIGNAL Berlin

BERLIN, June 11, 2026 - Twilio (NYSE: TWLO), the infrastructure for customer engagement in the AI era, announces AI Engineer and Creator of Guinndex Matt Cortland as a guest speaker at SIGNAL Berlin. Cortland will share how he used the Twilio Programmable Voice and its native integration with ElevenLabs to help power The "Guinndex", aka Guinness Price Index. He will also discuss the future of Voice AI and what developers can build when communications infrastructure and AI converge.

Originally created to track the changing price of a pint of Guinness, the project has since become an example of how developers are implementing Voice AI and communications APIs to build real-world research tools at scale.

By combining Twilio Programmable Voice with voice AI tech from ElevenLabs, the project gathered up-to-date prices straight from pubs and venues using natural, real-time calls. It's a powerful example of how Twilio's Voice AI can make large-scale research and customer engagement both simple and effective.

"What started as a project about the price of a pint became a real-world test of where Voice AI is heading," said Matt Cortland, AI Engineer and Creator of Guinndex. "Using Twilio's Programmable Voice infrastructure alongside conversational AI technology, we were able to scale one single idea to an entire country-wide index. What's exciting is that this points to a much bigger shift. AI agents are moving beyond chatbots and into real-world interactions. Platforms like Twilio will play a critical role in enabling those experiences at scale."

This project is a fantastic example of how innovative technology can make life easier for everyone. By placing thousands of calls, Matt Cortland was able to verify 6,554 Guinness prices. That's real social value delivered efficiently and affordably with Voice AI. It shows how the right technology can put transparent pricing within everyone's reach.

"Developers are moving beyond mere experimentation with AI; they are now building practical, real-world applications that deliver tangible value," said Peter Bell, Vice President of Marketing EMEA at Twilio. "Guinndex is a compelling example of the Twilio platform in action. By seamlessly combining programmable voice, conversational AI, and communications APIs, we provide developers with the essential toolkit to forge experiences that are both highly innovative and feel deeply human".

Twilio's SIGNAL conference series brings together developers, builders, and business leaders to explore the future of customer engagement, AI, communications, and digital experiences.
