We build brave brands that aim to have a say.

Miller O'Connor is an independent creative agency from Barcelona founded and led by women in 2017. We gather the best talent in the industry to deliver strong strategy, solid ideas and inventive executions to make brave brands truly matter to people.

CRAZY ABOUT CREATIVITY,
MAD ABOUT CHANGE.

We believe that only genuine ideas will make people care. Our brands and ads are built on transparency, disruption and connection, rather than on advertising inside jokes or explosive executions without substance. No matter the format or outcome, we create strong bonds between people and brands.

Our way of doing it?
Head on the clouds, feet on the ground.
