Calven is an AI-powered platform that deploys nine autonomous agents across competitive intelligence, win/loss analysis, ICP profiling, personas, positioning, and messaging for B2B product marketers. Each agent owns its domain and feeds a shared knowledge base called the Universe, which stays in sync so updates cascade automatically across battle cards, messaging, and campaigns. Calven connects via MCP to AI tools like Claude, ChatGPT, and Gemini, letting teams query their always-current marketing data directly. The platform also ingests signals from sales calls, CRM data, and Slack to keep documentation up to date without manual effort.
