Introducing Alkimi – A decentralised replacement to the inefficient legacy programmatic ad exchanges with the mission to restore the value exchange between advertisers, publishers and users.

Alkimi is powered by the Hypergraph – a revolutionary blockchain technology – trusted by the U.S. Department of Defense – which allows us to provide the fastest, infinitely scalable solution with 0% fraud, minimal transaction fees and complete end to end transparency.

Alkimi Exchange helps you create ad products, proven to be successful by walled gardens, across the open web.

Join us in creating Something from Nothing.

Alkimi Exchange

The World’s First Decentralised Ad Exchange

We think about Advertising differently, so we are building the world’s first decentralized ad exchange, where:

  • Users aren’t a Product
  • Publishers aren’t at the behest of Facebook and Google
  • Advertisers can deliver their message with value


Using the principle of Generative Economics, the Alkimi Exchange will reward Users, Publishers and Advertisers for rebuilding the intended value exchange of the Open Web. Fewer Ads, Better User Experience, Increased Engagement.
