FuseAI is a Y Combinator-backed startup on a mission to revolutionize enterprise automation with vertical AI agents. We’re building a new agentic operating system designed to transform how GTM (Go-To-Market) teams operate—think Salesforce meets OpenAI Operator. Our platform empowers organizations to automate their entire sales cycle through an AI-powered interface, streamlining lead generation, customer engagement, and deal management in seconds. Our AI Agents replace bloated sales tech stacks, making teams 10x more productive. With a powerhouse founding team that combines deep GTM expertise and a decade of machine learning innovation, FuseAI is positioned for exponential success. This is your chance to be part of something groundbreaking.
