Industry
Food & Beverages
Customer Background
The world’s second-largest coffee chain set out to elevate the coffee experience for U.S. customers during the peak of the COVID-19 pandemic. To ensure safety, convenience, and consistency, Costa Coffee introduced smart cafés, which are AI-powered autonomous coffee vending machines capable of delivering café-quality beverages in just 90 seconds, 24/7.
Sigma Solve partnered with the coffee chain to bridge the gap between emerging technologies and the familiar convenience of a traditional café, enabling a seamless, automated, and scalable coffee experience.
