ID5: The Identity Layer for a Fragmented Web

How a 82-person team is building the infrastructure for post-cookie advertising

The cookie is dying, and the ad industry is panicking. ID5 isn't just preparing for this reality—they're architecting it. By turning fragmented user signals into a unified, scalable identity framework, they're solving the addressability crisis that threatens omnichannel advertising.

"ID5 isn't selling a tool—they're selling the infrastructure that makes the entire ecosystem work."

The Identity-First Customer

ID5's clients aren't just advertisers—they're the entire media supply chain. Publishers struggling with signal loss, SSPs needing better bid density, and DSPs requiring accurate targeting all converge on ID5's platform. With 47% direct traffic, these aren't casual visitors; they're essential stakeholders logging into a mission-critical console. The 70 monthly searches for 'ID5 careers' reveal a company that's become a talent magnet in adtech's most technical niche.

The Acquisition Strategy

ID5's acquisition of TrueData wasn't just a purchase—it was a statement. By absorbing 'the digital identity company,' they signaled that identity isn't a feature; it's the foundation. The 140 monthly searches for 'Truedata' show a legacy of trust now flowing into ID5's brand. This isn't incremental growth; it's strategic consolidation of the identity layer.

What makes ID5 unique is their positioning: they're not a DMP, not a CDP, not a DSP. They're the connective tissue between all three. With a tech stack built on Vue.js and Nuxt.js for a modern, reactive interface, they're serving a technical audience that demands reliability and speed. The 26% traffic from undefined countries suggests either a global footprint with poor analytics or intentional stealth—both are telling.

  • Omnichannel identity resolution (not just web)
  • Privacy-first by design (GDPR/CCPA native)
  • Open ecosystem approach (not walled garden)
  • Real-time matching at scale (not batch processing)
They don't own media buying
They make everyone else's data more valuable
They don't manage creative
They enable accurate targeting without personal data
They don't offer analytics dashboards
They future-proof against cookie deprecation

The Identity Infrastructure Play

With $15.8M in revenue and a focused team of 82, ID5 is building the critical infrastructure that will power advertising's next decade. The question isn't whether identity matters—it's whether you can afford to be without it.
