    Financial Datasets is an applied AI research lab building search and data infrastructure for agents, starting with financial markets. We turn filings, company disclosures, and market data into structured, searchable information - helping agents find relevant facts, answer financial questions, and monitor markets in real time. For 40 years, market data was built for people reading screens. We're rebuilding it for agents that research every company, all day, across the world.

    Multiplier helps institutional investors research stocks and manage their portfolios. We're live with six 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. "Multiplier has flipped those percentages."
