What FatTail does
FatTail is a Calabasas-based advertising technology company founded in 2001 that builds direct advertising order management software for premium publishers and media companies. Its core platform, AdBook OMS (also marketed as AdBook+), is a cloud-based, API-first order management system built on Microsoft Cloud that manages the full lifecycle of direct ad deals across display, video, CTV, DOOH, audio, events, broadcast, and print. The company complements the OMS with FatTail Portal, a self-serve platform for advertisers that can be licensed independently for smaller publishers and SMB clients, supporting automated creative collection, billing, reporting, and AI-powered product recommendations.
FatTail generates revenue primarily through enterprise SaaS subscriptions sold on a quote-based, annual billing cadence, with a consultative direct sales motion targeting publishers and a parallel self-serve motion via Portal. The platform is used by more than 10,000 publishers and processes $11.5 billion in annual ad revenue, 181 billion ad impressions per year, and 1.7 billion+ monthly unique views. Notable customers include American City Business Journals, Bobit Business Media, GSTV, Cox Automotive, Tagesspiegel, and a major retail media publisher. Technology integrations include native two-way Salesforce CRM connectivity, real-time forecasting via Burt Intelligence, and hundreds of documented API endpoints for ad servers, billing systems, Snowflake, and project management tools. The platform holds SOC 1 and SOC 2 Type 2 audits and is CCPA/GDPR compliant.
In March 2025, FatTail was acquired by Chartbeat, backed by private equity firm Cuadrilla Capital, to form a unified editorial and revenue platform combining Chartbeat's audience intelligence with FatTail's ad operations capabilities. Following the acquisition, FatTail operates as part of Chartbeat's platform portfolio alongside Lineup, Tubular, and other media technology assets.
