The Brains Behind the Data

Company Timeline

  • 2010

    Complementics has its roots in a company called Growth Systems. Founded in 2010 Growth Systems was launched to focus on digital advertising and big data.

  • 2013

    Growth Systems founder, Walter Harrison, met with eContext in 2013.

  • 2015

    Soon, the two companies realized that mobile data and taxonomy could, well, “complement” each other, so eContext acquired the company and relaunched it in 2015 as Complementics.

  • 2017

    Complementics now manages data from more than 500M devices.

  • 2018

    Complementics manages data from more than 1B devices.
