"Bryony's book builds on the first edition and continues to offer a really sensible and holistic marketing approach that fits perfectly with a structured sales approach. Solid marketing and sales theories are pulled together in the digestible analogy of finding and plugging 13 leaks in a funnel. Unlike many marketing books, Bryony encourages fixing problems with existing customers and optimising the win probability of identified opportunities as well as generating more leads and prospects. Ideal for small businesses, the book is supported by a comprehensive web school to encourage self-sufficiency and informed decision making."
