Technical Lead

We think too much marketing isn’t us. It’s mass markets, not audiences of one. Homogenous groups are to be targeted, not individuals to be inspired. Segments to reach, not people with their own ideas and ambitions. It’s one size fits all, and it’s dull.

When it comes to individuals, we’re fierce. We stand up for individuality. We speak up against bland, broad-brush generalizations. We fight for solutions that adapt to the individual’s needs, beliefs, behaviors, and aspirations. And we commit to doing this in every aspect of our work for clients and their consumers.

We actively foster an inclusive workplace where diversity and individual difference are valued and leveraged to achieve the agency’s vision. And most importantly, we value every individual’s well-being.

We are Fiercely Individual.

At RAPP, we are fiercely focused on the individual and how we can create value from every individual’s experience with a brand. We do this across three capability areas: customer-centric consulting, creativity that inspires action and customer experience management.

Our data analysts know who that person is. Our strategists understand what they want. And our award-winning technologists and creatives know how to get it to them.

RAPP is an integral part of Omnicom’s Precision Marketing Group, comprising 4,000 creatives, technologists, strategists, and data and marketing scientists across 40 global markets.
