Gist Answers allows publishers to integrate AI-driven search, summarization, and recommendation tools directly into their digital platforms, enhancing user engagement and restoring control over the search experience. “Search has always shaped how people discover knowledge, but for too long publishers have been forced to give that power away,” said Bill Gross, CEO and founder of ProRata. The platform drives longer sessions and greater value, with early partners like The Atlantic and Popular Science reporting deeper audience engagement.
ProRata’s core content attribution technology ensures ethical, licensed use of content from over 700 high-quality publications worldwide. Publishers can license their content to inform Gist Answers on third-party platforms, creating new revenue streams. The platform integrates with Gist Ads, transforming AI responses into premium ad inventory with native, conversational ads aligned with user intent. “By contributing our content to the Gist network, we know it’s being used ethically,” said Nicholas Thompson, CEO of The Atlantic.
The $40 million Series B, led by Touring Capital with participation from Mayfield Fund, MVP Ventures, and others, will fuel Gist Answers’ expansion and enhance its features. “ProRata is addressing this inflection point with a market-neutral model designed to become the default platform for attribution and fair monetization,” said Nagraj Kashyap, General Partner at Touring Capital. This funding builds on ProRata’s prior $25 million Series A round led by Mayfield Fund in 2024.
ProRata’s approach redefines the role of publishers in the AI era, ensuring that trusted journalism remains central to information discovery. “With Gist Answers, our audience can engage directly with us and get trusted answers sourced from our reporting,” said Jeremy Gulban, CEO of CherryRoad Media. The platform’s ethical model, which prioritizes transparent attribution and proportional compensation, positions ProRata as a leader in sustainable AI-driven search and advertising.
