Endless Customers is the business growth system from IMPACT, created by Marcus Sheridan and the team at IMPACT, and the evolution of their earlier framework They Ask, You Answer. Built on the 4 Pillars of a Known and Trusted Brand — say what others won't say, show what others won't show, sell in a way others won't sell, and be more human — the system teaches companies to earn buyer trust and own their marketing in-house. IMPACT, founded in 2009 by CEO Bob Ruffolo and headquartered in Cheshire, Connecticut, is a coaching and training company, not a traditional agency. The system is the subject of the national bestseller Endless Customers (Wiley, 2025), a weekly podcast, and the Endless Customers Live conference.
