When McDonald’s wanted to innovate quickly on a new concept to engage Gen Z, we helped a dedicated internal team design and build an “out of this world” omnichannel experience in less than a year.

The CosMc’s experiment is continuing the rich culture of innovation at McDonald’s, creating buzz across the QSR industry and overwhelming excitement among customers.

The Vision


McDonald’s is part of the fabric of culture in every market where we operate. What better time to explore new ways of working and innovate at pace, testing ways to be culturally relevant to the next generation of fans?

The CosMc's sign stands tall on a sunny summer day.

With over 40,000 restaurants across more than 100 countries, McDonald’s is an iconic brand that pioneered quick service and continues to lead the QSR market. From such a position of strength, many companies would just stay focused on their core business. Instead, McDonald’s leaders saw an opportunity to explore a new approach for the changing customer preferences.

What would later be called CosMc’s started out as a loosely defined vision for a unique service experience to engage the next generation of fans with a beverage-led menu. Leaders wanted to develop the concept with a focus on speed and learning. 

The full-time journey to bring CosMc’s to life began in February 2023. Slalom was engaged soon after to help craft the omnichannel vision and build the digital foundation.


CosMc’s has been so exciting because we’ve created an entire concept from scratch. And we did it as one team across many partners even beyond Slalom.

The Solution

As the CosMc’s experience came into focus, the team moved quickly, building together through thousands of hypotheses, tests, and decisions.

Customer Impact

The CosMc’s concept was fully unveiled on December 6, 2023, in the McDonald’s Investor Update. The next day, the first pilot store opened to a deluge of consumer and media enthusiasm.

The anecdotes speak volumes. 

One McDonald’s fan flew from London to try CosMc’s. Another drove from Canada. Three TikTok influencers took a 16-hour road trip from Nebraska to order and taste the entire menu. Thousands of people, including many cars full of Zoomers (Gen Z), waited in line for six hours or more on opening weekend. The launch was featured on major news outlets, on shows like Saturday Night Live and Good Morning America, and across social media.

 CosMc’s exemplifies what’s possible when you break down silos to collaborate with customers at the center. It demonstrates innovation at a pace that was previously unknown in the McDonald’s system, and this pilot is far from over.

Iteration on the menu, experience, and operations continue, with a goal of approximately 10 pilot restaurants by the end of 2024. 


To think that we built something people are so excited to be a part of is amazing. Initial results have been promising, and we continue to test and learn to make the concept even better.
