  • Digital


Critical Mass designs unparalleled brand experiences that connect with people. We got our start back in 1996 when a design visionary and a successful entrepreneur came together with a focus on digital experiences in a rapidly evolving space. Since then, we’ve helped local, national, and global brands reimagine digital and transform their businesses through strategic consulting, innovative creative ideas, and cutting-edge technology thinking. And through it all, we go the extra mile to be the best partners we can be. 

We take data, creativity, and technology and connect them so that entire ecosystems work in a seamless, dynamic, and personalized way. It’s a paradigm shift in the way digital works. We learn about each customer through research and testing, but also through every interaction (data), and we use what we learn to inform the next step. By blending forecasting, machine learning, and real-time optimization with an ownable and flexible design system (all stuff we’re really good at), brands can seize opportunities the instant they’re revealed. Customers, in turn, get a better experience and a more connected journey. Simply put, a connected ecosystem is a true win/win, and it encompasses the touchpoints the world knows well (sites, apps, and social), as well as the ones we’re just entering (the metaverse and beyond). And that’s what we’re delivering for some of the world’s greatest brands—the next frontier in digital, with a relentless focus on the customer.

We are now majority-owned (99%) by Omnicom Group Inc. (NYSE: OMC). 
Omnicom is one of the largest holding companies for global advertising, marketing, digital and communications services firms. Their global revenue is over $15 billion, and they have more than 5,000 clients in over 100 countries.

Today, we are over 1,200 employees across 12 global offices and remain true to our roots. We're transparent, honest, passionate and have a can-do attitude that our clients notice and appreciate.
