Critical Mass


Critical Mass was founded when a design visionary and a successful entrepreneur came together with a focus on digital experiences in a rapidly evolving space. Over the next 23 years, we helped global brands reimagine digital and transform their businesses through strategic consulting, innovative creative ideas, and cutting-edge technology thinking.

Today, we are 950 employees across 12 global offices. Even though we’re much bigger than when we started out in Calgary, we remain true to our roots—we’re transparent, honest, passionate, and have a can-do attitude that our clients notice and appreciate. Our executive and global leadership team use an open and accessible management style to drive our success on all fronts: innovating our services, mentoring our talent, and ensuring we deliver industry-leading work. We believe this is core to our success as a digital leader.

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.
