What if sales success isn't learned, but hardwired by your late teens?

Built on 45 years of research and over 30 million assessments, SalesDNA reveals the innate talents and work ethic that separate top performers from everyone else. Only 17% of people possess the natural wiring for sustained sales success and no amount of training can create what isn't there. Drawing on decades of insights from competitive sales environments and elite performance across sports and business, this book is your blueprint to SELECT, DEVELOP and RETAIN true revenue generators.

SalesDNA is the playbook for sales leaders building high-performing teams where individuals own their results and thrive on accountability. It is also a self-discovery tool for anyone who wants to unlock their full potential or determine if they are among the elite 17%.

Revenue generation requires revenue generators. Identifying them is like panning for gold in a pile of rocks, many look promising, few are valuable.This book gives you the tools to stop guessing and start hiring gold.

Skills can be taught. SalesDNA is what you're born with.
