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 organisation 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 behaviours

  • 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 personalised 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 internalise brandtech capabilities, keep abreast of innovations, and remain ahead of your competition


We believe ‘data-driven’ goes hand in hand with ‘creative’ to drive better results. Creativity is crucial to design a good data strategy and inversely, data is the golden asset to guide successful creative development and execution.

  • We combine data science with media and digital expertise to create a new form of storytelling fueled by data

  • We design and build creative solutions to drive more people who matter to your online and offline points of sales, using first and third-party data

  • We adopt a “Start small / scale fast” approach

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

Drawing on his consulting experience at fifty-five, he published a second book: Webanalyse, des données à l'action (Dunod 2013).

  • Jean Neltner JWIN Laureate

    A true expert in online business development, Jean has worked in all sectors: finance, technology, CPG, B2B, etc. Before co-founding fifty-five, this EM Lyon Business School alumnus participated in the rapid growth of the Internet sector as Business Development Director at Lycos, Infonie and Egg. He then became Head of Strategic Partnerships for Southern Europe at Google, where he met his future partners.

  • François Costa de Beauregard Program Manager

    After graduating from Sciences-Po Paris and Paris Dauphine University, François started working at L’Oréal before changing careers and joining Google where he was in charge of the retail accounts. He then put his expertise in SEM and web analytics to the service of Keyade and participated in the creation of Keymetrics, the agency branch specialized in web analytics and web testing.

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 and Hong Kong – 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.
