Alkimi

Alkimi is a programmatic advertising infrastructure company operating a blockchain-based ad exchange under the legal entity XSM Limited (BVI). Its core offer is an SSP-style marketplace that records ad transactions on-chain, aiming to reduce intermediary fees and provide auditable delivery for advertisers, agencies, programmatic traders and publishers. It also offers transaction transparency tools, placement analytics, self-service access through external DSPs, and a managed buying service. The company makes money primarily from a take-rate on media transactions flowing through its exchange, supplemented by managed-service fees and token-linked protocol economics tied to AdFi. Its customers are businesses rather than consumers: publishers monetising inventory, agencies and traders buying media, and brands seeking lower-fee, more transparent programmatic execution.
