Fuse AI

Fuse AI is a Y Combinator backed sales platform with AI agents for prospecting, data enrichment, multi-channel outreach, buyer signals and workflow automation, reachable directly or through MCP from assistants like Claude.

Fuse AI is a revenue automation platform that uses AI agents to handle the repetitive parts of outbound sales: finding prospects, enriching their data, spotting buying intent and running outreach. It is aimed at sales reps, founders, RevOps teams and GTM engineers who want one system to replace a pile of separate prospecting and sequencing tools. The company is based in San Francisco, is backed by Y Combinator, and says more than 1,000 startups and enterprises use it. The product is organised into four areas. Prospect searches a database the vendor puts at 850M+ contacts and 40M+ companies, then verifies and enriches records across 40+ data providers. Engage automates personalised outreach over email, LinkedIn and phone. Signals tracks more than 50 real-time buying indicators on target accounts, such as website visits, wider web activity and competitor interactions. Automations lets teams define triggers and conditions that move work through prospecting, enrichment, CRM updates and outreach without heavy technical setup. Its Agentic Search finds companies and people by intent and context instead of plain keyword filters. A distinctive angle is how agents reach the platform. Fuse exposes an MCP server and a skill file, so assistants such as Claude, OpenAI tools, Cursor, Gemini or GitHub Copilot can add it and run sales workflows on a user's behalf, after the user signs in. A separate machine-readable version of the site is published for agents. For larger organisations, the homepage lists granular permissions, guardrails that require human approval, a single admin console, usage and spend visibility, isolated cloud environments per agent, and SOC 2 Type I, GDPR, CCPA and CASA Tier 2 compliance. Among alternatives, Fuse competes with data and prospecting vendors such as Apollo, ZoomInfo and RocketReach, and it publishes its own benchmark claiming higher data accuracy than all three. Those figures come from the vendor and should be tested against a team's own target market. It can replace point solutions or run beside an existing stack.
