Holding Identity to
Higher Standards

At ID5, were committed to supporting the sustainable development of the digital economy and enabling free, privacy-safe access to content and services.

This mission began with a simple belief: the digital advertising ecosystem deserved better, smarter identity technology that delivers greater ROI without compromising peoples trust. Co-founders Mathieu Roche and Pierre-Antoine Durgeat brought this vision to life by assembling a team of seasoned adtech experts and securing the backing of leading investors to drive meaningful, lasting change across the industry. In 2025, ID5 acquired TrueData to expand our operations in the U.S. and integrate technology that strengthens our offering, delivering even greater value to our partners and to the digital advertising ecosystem as a whole.
