  • “The people make the difference”

    FatTail, and really the FatTail team are way different than any other vendor I have worked with and it makes a world of difference.

    Matthew Pferschy, Director, Ad Operations, American City Business Journals

  • “Our relationship with them is truly a partnership.”

    “FatTail takes a very consultative approach to everything they do. They really listen to our needs and don’t try to push a new solution or path. The level of flexibility and customization we achieve with their platform relative to other vendors in the marketplace has been huge. We don’t have to worry about the performance of the platform, which has freed us to focus on the growth of the business.

    Our relationship with them is truly a partnership. They’re not a vendor. I look at them as a part of our business who are integral to our success. They’re incredibly responsive, and they deeply care about the relationship. Plus, they’ve had so little turnover in the 4 years we’ve been working with them. It’s remarkable.”

    Senior Director, Major Retail Media Publisher

  • "Every day of the week we validate that we made the best decision.”

    “We got much more than we bargained for with FatTail. Yes we met the OMS requirement, but we also gained a partner in FatTail, who has been a digital transformation partner to our business. With their technology and their expertise, we've advanced from a world where everything was manual, to digital automation. That means better, timely data for our decision making."

    Paul Hausback, COO Bobit Business Media

  • “Massively reduced friction, and helps us move to contract faster than ever.”

    “Since implementing AdBook in 2019, we've reached new heights in professionalizing and advancing our Ad Operations systems and processes. Setting up AdBook, especially within the Salesforce environment, has massively reduced friction for our sales team who now have more autonomy to sell with quicker access to inventory, more seamless approvals. It helps us move to contract faster than ever and for our behind-the-scenes operations teams, ensures that delivery is flawless. Reporting from AdBook - including scheduled reports that drop into SFTP servers - powers other tools in our tech stack furthering AdBook as a central system in our platform.”

    VP Operations, B2B news and events, multi-platform digital media company

Why Publishers Choose FatTail for Direct Ad Order Management

At FatTail, flexibility and service are at the core of everything we do.

We work to understand your business and what makes you unique, and tailor solutions around it. Unlike general-purpose product, FatTail is built specifically around the direct advertising lifecycle.

We release new platform capabilities every month, and after more than 20 years and over $75 million of direct development investment, offer the most superior set of features in the market.

We know that what you need from ad tech continues to evolve, and we partner closely with our clients to evolve our platform so that it grows with you.

We are innovators. We’re not satisfied with what the industry has come to think of as OMS, which is why we’ve developed ours into a direct advertising platform that supports end-to-end deal automation.

The ideal OMS doesn’t just take orders — it drives revenue.

About FatTail

  • FatTail is an ad order management platform built for publishers selling direct advertising. It helps media companies manage proposals, trafficking, and reporting for guaranteed, direct-sold inventory — bringing the full campaign lifecycle into one system.

  • FatTail is built for digital publishers and media companies with a direct sales team. It's especially useful for publishers who sell guaranteed, premium inventory directly to advertisers and need a system that reflects the complexity of those deals — not a general-purpose ad server.

  • Google Ad Manager handles ad delivery. FatTail handles the business side — proposals, order management, billing, and reporting. FatTail integrates with ad servers rather than replacing them, sitting between your sales team and your ad server to keep what was sold in sync with what was delivered.

  • AdBook+ is FatTail's flagship order management system. It covers the full direct advertising workflow: building proposals, managing insertion orders, trafficking to your ad server, billing clients, and reporting on campaign performance — all from a single platform.
