It is where marketing teams do the work: research, briefs, content, campaigns, reporting, all in one place, alongside agents that carry the load with them.\nBuilt on 2B+ real user prompts and growing, Profound’s data shows you what people ask AI and what the models say back.

It measures what works and gets better every day.\nProfound is building the foundational agentic layer for modern companies.
