Powers of Reasoning was started in 2023 by founder and CEO Kate O’Brien, a 15-year Omnicom Media Group veteran tired of watching clients blindly sign the same types of media contracts without being offered a full menu of options.
So she set out to give clients more control over their buys, as well as the cost savings they’d been missing out on.
That has allowed her seven-person shop to maintain double-digit profit margins since its opening, punch above its weight and manage more than $100 million in media spend.
