Picture your ideal customer: friendly, eager to meet, ready to coach you through the sale and champion your products and services across the organization. It turns out that's the last person you need.

Most marketing and sales teams go after low-hanging fruit: buyers who are eager and have clearly articulated needs. That's simply human nature; it's much easier to build a relationship with someone who always makes time for you, engages with your content, and listens attentively. But according to brand-new CEB research--based on data from thousands of B2B marketers, sellers, and buyers around the world--the highest-performing teams focus their time on potential customers who are far more skeptical, far less interested in meeting, and ultimately agnostic as to who wins the deal. How could this be?

The authors of The Challenger Customer reveal that high-performing B2B teams grasp something that their average-performing peers don't: Now that big, complex deals increasingly require consensus among a wide range of players across the organization, the limiting factor is rarely the salesperson's inability to get an individual stakeholder to agree to a solution. More often it's that the stakeholders inside the company can't even agree with one another about what the problem is.

It turns out only a very specific type of customer stakeholder has the credibility, persuasive skill, and will to effectively challenge his or her colleagues to pursue anything more ambitious than the status quo. These customers get deals to the finish line far more often than friendlier stakeholders who seem so receptive at first. In other words, Challenger sellers do best when they target Challenger customers.

The Challenger Customer unveils research-based tools that will help you distinguish the "Talkers" from the "Mobilizers" in any organization. It also provides a blueprint for finding them, engaging them with disruptive insight, and equipping them to effectively challenge their own organization.
