Versium is a data technology company based in Redmond, Washington, operating within the advertising services sector. It maintains an identity graph that supports B2B2C marketing tools and services. The company engages with marketers to understand their challenges and refines its offerings to improve campaign effectiveness, generate demand, and re-engage customers while integrating with clients’ existing platforms. The firm’s origins trace to a poorly targeted direct email campaign, which motivated founders to apply data science and analytics to the marketing data that agencies and enterprises manage to improve ROI. In February 2026, Versium announced the Versium REACH MCP Server, a development that connects AI agents to its identity technology.
