Prorata.AI

What Prorata.AI does

ProRata.AI is a Pasadena-based AI infrastructure company founded in 2024 by Bill Gross that builds attribution, search, and advertising products designed to ensure content creators and publishers are credited and compensated when their work is used in AI-generated answers. Its core products include Gist Answers (an AI-as-a-service platform that embeds AI search, summarization, and recommendation in publisher sites), the Question Bar advertising format (sponsored questions surfaced within articles), and an Attribution Platform that implements a 50/50 revenue-share model with content partners. The Gist platform is operated as a wholly owned subsidiary and is the primary commercial vehicle, with ProRata.AI also licensing content access to AI companies.

The business model combines a take-rate revenue share (50% to publishers from ad income tied to AI answers citing their content) with subscription/licensing arrangements to AI developers and publishers. Distribution is hybrid: self-serve partnership onboarding via prorata.ai/partnerships/ paired with enterprise field sales targeting marquee media brands — publicly named partners include The Atlantic, TIME, Fortune, Axel Springer, Universal Music Group, The Arena Group, BuzzFeed, DMGT, Sports Illustrated, Frommer's, and BoardingArea. ProRata claims 1,000+ publisher partnerships, over 500 publishers on its attribution model, and Gist is projected to serve 500M questions by June 2026 and exceed 1B monthly by end of Q3 2026.

The company is privately held and venture-backed, having raised over $75 million including a $40 million Series B in September 2025 led by Touring Capital, with participation from Mayfield, Prime Movers Lab, Idealab, Bold, Calibrate, DMG, MVP, Revolution, XPV, and SBI Holdings. Leadership has been expanded with CRO Michele Tobin and CMO Peter Sloterdyk appointed in February 2026. Geographic reach spans the United States (Pasadena HQ) and Europe via a December 2025 partnership with Denmark's DPCMO to build a sovereign AI answer engine — the first of its kind.

Scale indicators7 records

Recent moves6 records

Expansion highlights6 records

Direct peers

• Tollbit: Tollbit operates a content-licensing and bot-payment infrastructure that lets publishers monetize AI bot scraping at scale. Like ProRata, it sits between AI companies and publishers as an attribution/settlement layer for AI-driven content use.
• Scale Post: Scale Post provides AI-content licensing and attribution infrastructure for publishers and AI labs, including revenue-share settlements. It targets the same publisher-AI attribution problem ProRata solves with its 50/50 model.

Broad incumbents

• Perplexity AI: Perplexity is a leading AI answer engine that cites publisher sources in generated responses — overlapping with Gist Answers. It is also a ProRata licensing counterparty, making it both a competitor (AI answer surface) and a customer (attribution settlement).
• OpenAI: OpenAI is both a major AI-answer incumbents (ChatGPT search) and a ProRata licensing customer. Its scale, distribution, and any first-party attribution or publisher-revenue products make it the most consequential competitive and partner counterparty.
• Anthropic: Anthropic (Claude) is a frontier AI lab that already pays ProRata for licensed content access. Its own evolving approach to citations and publisher compensation is a strategic variable for ProRata's licensing economics.
• Google (Search / Gemini): Google Search/Gemini is the incumbent being displaced in the zero-click-search era and a ProRata licensing customer. Google's AI Overviews and Search ad business are the structural alternative to Gist's question-based ad format.
• Microsoft (Bing / Copilot): Microsoft's Bing/Copilot combines search and AI answers and is a ProRata licensing counterparty. Its scale in enterprise distribution and ad-tech makes it a key potential partner-or-competitor for publisher-facing AI infrastructure.
• Cohere: Cohere provides enterprise AI models and retrieval-augmented generation infrastructure that overlaps with ProRata's knowledge-retrieval and attribution capabilities for publishers seeking AI search/summarization features.

Emerging players

• Originality.ai: Originality.ai offers AI content detection and authorship verification, partially overlapping with ProRata's accountability and content-authenticity positioning. It addresses a related (but narrower) slice of the AI-content provenance market.
• Jasper: Jasper is an enterprise AI content platform that addresses content creation workflows for marketers — adjacent to ProRata's publisher-side attribution and AI search/answer focus. Both operate in the AI-for-content commercial layer.
