FatTail was founded in 2001 by a team of executives with extensive backgrounds in the financial industry where they honed their expertise building financial models and services that reduce operational risk and optimize performance.

When they took a look at the online advertising industry, they realized that a book of advertising assets is very similar to a book of financial assets, and that many of the methods pioneered in the financial industry would benefit online publishers and advertisers and streamline ad sales and operations.

Since 2002, hundreds of publishers (including some of the most iconic brands in the world) have trusted FatTail’s products to manage their digital advertising business. Currently used by thousands of people every day, premium publishers process more than $5 billion in annual advertising transactions through AdBook+, the only unified direct and programmatic supply platform.

AdBook+’s cloud-based solutions, AdBookOMS and AdBookPSP, give publishers total control of media planning, sales, and revenue across a wide variety of advertising products and channels and offers Demand Side Systems differentiated “top of the funnel” inventory supply from the world’s most trusted brands.
