Guideline

Guideline pools actual invoiced advertising billing data from media agencies and standardizes it into one taxonomy across linear TV, streaming, digital, print, audio and out-of-home. Media planners, publishers and analysts use it to benchmark competitor spend, size markets and check what media inventory really costs. A second line of software manages media plans for agencies and brands, from annual brief through approvals, budgeting, reconciliation and actualization, with audience-first cross-media planning. The same spend data is packaged as ticker-level alternative data for hedge funds and investment researchers. Natural-language querying and an MCP server let teams reach the data and plans from AI assistants.
