Fuse AI: Build a Custom GTM Stack. One SDK. One MCP.
Behind the single interface, the company says it bundles 1,000+ applications, 40+ data providers, web scraping, AI research agents, managed multi-channel outreach infrastructure, workflows, AI context layer. Users can run it in Claude, ChatGPT, Perplexity, and more, or embed Fuse directly into your application. The MCP server does not map one-to-one to REST endpoints. It exposes one tool per Fuse feature area, and each tool is an agent that takes requests in plain language. The launch placed 10. on Product Hunt's weekly leaderboard for the week of October 5, 2026. Co-founder Saurav previously helped build GTM systems at Deel. The company is based in San Francisco and pitches itself as a mix of OpenRouter, Apollo, Clay and Zapier, competing with each of those point tools. For AI founders, this shows sales tooling moving to agent-first access, where MCP is the main interface and the dashboard comes second. Teams building agents can get prospecting and outreach data without stitching together separate vendor APIs. Teams selling GTM point products now face aggregators that turn them into interchangeable providers behind one layer.
