Penbryn Advisory was set up by Tim Sleep. Over a twenty five year sales leadership career in technology vendors and professional services, Tim has drawn on his training, experience and thoughts of industry peers to come up with a new approach to managing large complex deals.


Documented in his book 'Forecasting to Win', with contributions from leading commercial and procurement director, Dr David Feavearyear, Tim has developed a new and unique way to manage and review deals.


There is no more impactful element to an effective sales function than having a robust, simple and incredibly effective approach to deal management. It should be at the core of every leader's approach to optimising performance.

Contact Tim to understand more about the methodology and approach.
