The time for TRUST is now!

Over the last decade Real-Time Bidding (RTB) created massive efficiency for the digital advertising marketplace in opening large volumes of inventory, driving down prices and creating the opportunity for smaller sites and apps to thrive.

Today it has become a large $200B market that continues to grow at an accelerated pace with a supply chain that remains complex, fragmented, partly opaque and could be even more efficient.

In a context where decisions are increasingly made by technology, traditional processes do not apply and there is a need to bring a technological solution to what is essentially a technological problem.

As a global cross-industry initiative, TAG TrustNet is taking the industry to the next level as an always-on collaborative network providing the tools to certify the supply chain and allow everyone to be accountable, make responsible decisions and improve efficiency.

TAG TrustNet achieves this by automating the reconciliation of data across the supply chain and recording it in an immutable shared ledger as Shared Truth: a unified record for every single ad running through the supply chain made available in near real-time.




Responsible advertising for a responsible industry

With Shared Truth, TAG TrustNet enables what can be defined as Responsible Advertising based on 3 building blocks:

Know their business partners

every record can be tracked back to the legal entities that are part of the transaction

Know their business practices

every record gets cross-checked and verified based on financial and qualitative metrics

Make timely informed business decisions

every record gets reconciled and can be acted on in near real-time.

What are my benefits?
