Marketo Co-founder Launches AI Marketing Automation Platform Phave

Jon Miller, co-founder of Marketo, has launched Phave, a new AI-powered marketing automation platform for enterprise B2B organizations. After two years in stealth, Phave is now used by 10 companies. The platform replaces traditional rules-based triggers with AI reasoning models to handle complex B2B buying scenarios. Phave treats contacts, accounts, and buying groups as first-class objects, and introduces a 'playlist' concept that dynamically sequences marketing tactics based on real-time data and preferences. It also exposes 319 tools through the Model Context Protocol (MCP), allowing external AI agents to trigger actions. Miller aims to address the limitations of legacy MAPs, which he says have failed to adapt to modern B2B buying behavior.
