Our customers are Fortune 500 companies across multiple verticals - including CPG, food, beverage, consumer technology, telecom, and financial services - as well as the world’s largest advertising agencies and media platforms. We are unapologetically supportive of brand advertising, and work hard every day to prove its value; we know if companies can measure the value of those dollars, they’ll spend more. Brand advertising pays for not only the movies we watch and music we hear, but the journalism we read and the information we access. In short, brand advertising supports the free flow of information through society. So, we’re proud to be the first company dedicated to using data science to show enterprises the true effectiveness of their brand spend. We are backed by leading venture investors (Y Combinator, Uncork Capital, Bloomberg Beta, Initialized Capital, PivotNorth, Ridge Ventures, Industry Ventures, Conductive Ventures,) and leading MarTech founders & CEOs. We’re a humble but ambitious team that takes its work seriously but never ourselves. Come join us.
