Cube, created by founders Artyom Keydunov and Pavel Tiunov, provides a universal semantic layer that sits between data warehouses and the tools that consume data. By defining metrics, dimensions, and access controls once, teams ensure that dashboards, embedded analytics, internal apps, and AI agents all return consistent numbers. Cube exposes data through SQL, REST, and GraphQL APIs and includes caching for performance at scale, with Cube Cloud running across tens of thousands of servers and millions of users. As enterprises connect LLMs and agents to their data, Cube's governed semantic layer becomes a control point that keeps AI answers aligned with official business definitions. The company raised a $25M Series B in June 2024 led by Databricks Ventures, with participation from Decibel, Bain Capital Ventures, Eniac Ventures, and 645 Ventures, bringing total funding to roughly $48M.
