About
ProRata AI builds AI-powered search, advertising and attribution systems designed around licensed content rather than uncompensated scraping. Founded in 2024 by serial entrepreneur Bill Gross (Idealab) and headquartered in Los Angeles, the company's core proposition is a revenue-sharing model that pays content partners 50% of revenue attributed to their material, alongside attribution technology that routes traffic back to original sources. The approach targets the economics of "zero-click" generative search, where AI answers historically displaced publisher traffic without compensation. ProRata has signed hundreds of content partners and drawn public endorsement from Universal Music Group chairman and CEO Sir Lucian Grainge. The company raised a $65M Series B in September 2025.
