Teikametrics is an advertising technology company headquartered in Boston, Massachusetts that provides AI-powered advertising optimization for brands and sellers on Amazon and Walmart, building its optimization engine on a distinctive philosophical foundation: that advertising optimization should be grounded in the business economics of each product — unit economics, margin contribution, inventory availability, and velocity goals — rather than solely optimizing for advertising efficiency metrics like ACoS that can be misleading when disconnected from the underlying profitability of the units being sold. The company was founded in 2012 and has served Amazon marketplace sellers since the early years of the sponsored advertising platform.
