Marilois Snowman

Founder & Chief Executive Architect


Marilois began her career as a journalist, where she discovered her passion for asking and seeking answers to the big “what-if and why-not” questions.  Her inquisitive nature was the fuel for the creation of Mediastruction as a data-led media agency – one that continues to be uniquely positioned in its use of AI tools and advanced modeling as core inputs to each media plan. Marilois’ thought leadership is highly sought after.  Her weekly blog on the Mediastruction website is often picked up by industry outlets.  She is a contributor to MediaPost, and she serves on the Scarborough Advisory Board of Nielsen Media Research, the I-COM Data Storytelling Council, and the I-COM Incrementality Council.

Jenna Umbrianna

Chief Development Architect


Jenna has spent her entire career at the forefront of the data-driven media industry, building business units around emerging adtech capabilities since the first self-service buying platforms emerged in the late 2000s. At Hill Holliday she launched one of the industry’s very first programmatic trading desks. At Havas she launched Affiperf in North America, and as GM grew the programmatic practice >10x in 3 years. Later, as GM of the programmatic media agency Anagram, Jenna again led an agency transformation — doubling the size of the business through a transition from programmatic to cross-channel platform buying. In 2019 Jenna was named a Media All-Star by Adweek, and was noted as “a force for innovation throughout her career.”
