What is Fuse AI?
Fuse AI is a Y Combinator-backed AI sales platform positioned as an agentic harness on top of existing sales stacks. It offers prospecting, data enrichment, multi-channel engagement via email/LinkedIn/phone, buying signal intelligence, and enterprise guardrails. Its most distinctive recent move is an MCP server that lets Claude, OpenAI, Cursor, Gemini, and GitHub Copilot execute sales workflows. The website makes strong self-reported performance claims against Apollo, ZoomInfo, and RocketReach. MRR, growth, and pricing are not publicly disclosed in the provided content.
