Our values

The rapid shifts in technology have dramatically changed the way people interact and engage with brands. As media, distribution and creativity are being disrupted, the distinction between online and in-store sales has been blurred.

55 is a new breed of data company that helps brands leverage data and technology, to engage people better, faster and cheaper. We are a proud member of You & Mr Jones, the world’s first BRANDTECH* group, since January 2016.


We believe data is an asset that you should have full ownership of, and that it should be distributed across your organization and put into action in a transparent and actionable way.

  • We help you make sense of every dollar invested with actual measurement, not estimates

  • We provide no black box models and help you unravel the mysteries of attribution, programmatic or third-party data with greater transparency on your customer’s behaviors

  • We are tech-agnostic and are not compensated through technology or inventory rebates


We believe that you should understand, decide and control how your data is used to deliver personalized brand experiences.

  • We help you take ownership of data and technology through a direct relationship with tech providers and the unbundling of services

  • We set up and run your DMP for you, or the best brandtech stack based on your needs

  • We help you internalize brandtech capabilities, keep abreast of innovations, and remain ahead of your competition


We believe that brands’ ability to innovate is the condition for them to excel in today’s multi-channel, connected world. And we believe innovation relies on three bedrocks: data, technology and creativity.

  • We leverage our close relationships with the leading technology companies to design and build inventive programs for you to drive more people to your sales points

  • We combine data-drivenness with creativity to fuel a new form of storytelling

  • We adopt a “start small / scale fast” approach to assist you in successfully launching innovative projects

*BRANDTECH: the art of combining marketing and branding with the power of technology, to help marketers build brands better, faster and cheaper.

Our services

55 was founded in 2010 by the former senior management team members of Google Europe. We have grown rapidly from a startup into a 150-employee business with a presence in Paris, London, Shanghai, New York, Hong Kong and Geneva – helping brands leverage data and technology to drive better, faster, cheaper marketing.

Why 55? Because in the physical world, 55% of people entering a store leave having purchased something – that’s far more than visitors on e-commerce platforms. Yet digital is not competing with, but rather completing – and even augmenting – the traditional shopping experience. Our brand is a reminder of the gap that used to lie between both worlds, and of the synergies awaiting those who embrace the brandtech revolution.

We are a proud member of You & Mr Jones, the world’s first brandtech group, since 2016.
