CEB, formerly Corporate Executive Board, now a part of Gartner, was a company providing best practice research, benchmarks, and decision support tools to business leaders in HR, Finance, IT, Marketing, Sales, Customer Service, Strategy, R&D, Procurement, Legal, and Compliance functions globally.

[4][5] CEB offered its first subscription research program to retail banking executives, the Council on Financial Competition, in 1983 when it was part of The Advisory Board Company.

Unlike most of those companies, CEB was profitable, continued to grow, and ultimately achieved a valuation over $3 billion at its peak.

[16] Evanta is based in Portland, Oregon, and provides events, platforms and information offerings to train IT-security, human-resources and finance staff in collaboration and best practices.

[19][20] The third book, The Challenger Customer was written by Matthew Dixon, Brent Adamson, Nick Toman, and Patrick Spenner and published on September 8, 2015.

The company, previously on NASDAQ, entered into an alliance with NYSE Euronext in 2010 and began actively trading as CEB in 2012.
