We’re on a mission to work with the world’s most innovative marketers.

The biggest threat to business isn’t rejection: it’s indifference.

At least half the stuff we’ve worked on with them is not traditional advertising.”— JetBlue Client

We’re Mullen. Proud (yet humbled) to be recognized among the elite and most innovative marketing organizations in the world.

Our philosophy is Unbound – we harness the power of creativity, technology, media and community to help our clients achieve their greatest ambitions in a post-digital, consumer-controlled world. We believe the biggest threat to brands isn’t rejection, but rather indifference, so we set out to make our clients’ brands a productive part of consumer lives and to make spending time with those brands worthwhile.


Mullen’s culture is entirely about limitless possibilities and a relentless belief in a future that is bigger than the past. It’s how we started our company. It’s how we built it. It’s how we continue to evolve and innovate. Check out the video above to see the latest creations in the Mullen innovation lab.


We’re fortunate to work with a number of courageous, thought-leader brands. These are clients who make us better and push us farther, who are eager to take risks, who want to do things that have never been done before.

In her three years at Mullen, the agency has doubled in size, opened offices in San Francisco and Los Angeles and twice been named to the Ad Age Agency A-List.

  • joe-grimaldi
    JOE GRIMALDI Chairman I love this agency that I have been part of for over three decades, ever since we were only a dozen people. Before I became Chairman, I was CEO, President, COO and Director of Client Services. I started my ad career in NY after brief stints as a professional musician, a custom-design motorcycle builder and a construction worker. It has been my great fortune and privilege to help build this company and the underlying culture that makes its success sustainable. I believe in embracing change and taking risks, hiring people immensely more talented than myself, giving them room for their passions to soar, harnessing their collective force with a meaningful shared purpose, and doing all of this in an egalitarian, managed-chaos environment that fosters collisions of diverse thought and skills for inspired innovation and creativity on our clients’ behalf. My greatest contribution is installing our current leadership team. They instinctively possess the Mullen DNA, and they have the vision, talent, desire, determination and camaraderie to take our agency – and, just as importantly, our clients – to places that will greatly exceed expectations.X  Close
