Alkimi

Emerging challenger in the programmatic advertising exchange space, differentiating through blockchain-based decentralization and transparency

Alkimi is an agentic advertising marketplace where AI agents representing buyers and sellers can meet to negotiate and transact media directly, with every deal recorded in real time in a form both parties can independently verify.¹ The platform removes opaque intermediaries from the advertising supply chain, redirecting value between advertisers and publishers by exposing where spending was previously lost, improving transparency, reducing fees, and accelerating payments.² Because every programmatic deal traditionally runs on two separate records — one held by the buyer, one by the seller — discrepancies are common; Alkimi's research with WPP found records disagreed in 95.3% of simulated deals, a problem Alkimi addresses through Deal Sheets, a single shared record that both agents write to at the point of agreement, eliminating the need for post-settlement reconciliation.¹ Alkimi operates as neutral infrastructure built on open standards, including AAMP and AdCP, providing holding company agencies and other buyers with the audit documentation and interoperability needed to reduce proprietary lock-in risk.³ The company has adopted the full Sui blockchain stack — including Walrus, Nautilus, and Seal — to bring its commercial supply chain onchain, and has already engaged brands such as AWS, TikTok, Currys, and Polestar through its platform.² Source 1: iabuk.com — Alkimi Exchange Source 2: sui.io — How Alkimi and Sui Are Fixing the Broken Ad Ecosystem Source 3: alkimi.org — What US Holding Company Agencies Need to Know About Agentic ...
