About

WithAI helps institutional investors research stocks and manage their portfolios. We're live with four hedge funds, and our users spend 4+ hours a day in the platform. Investors who try "nearly every tool on the market," to quote a client of ours, "wind up with an unwieldy collection of fragmented point solutions." Those who focus on building a great setup with general agents are instead "signing up for a full-time job." So we deploy a platform called Multiplier that unifies structured data, unstructured data, AI work, human work, and tacit firm knowledge in one secure, governed, customized application. Our first vertical: independent equity funds with $250M-$5B of assets. They know AI is essential for staying relevant, but they don't have the time or talent to figure out what to do about it. But once we deploy Multiplier––"We used to spend 80% of our time gathering information and 20% of our time acting on it," said one customer. "WithAI has flipped those percentages."
