As a Speaker and Facilitator, David's interactive workshops are unique and here is what some of his clients have said.

David applies his extensive experience while being exceptionally committed to learning; he is an exceptional listener who prides himself on solving client problems and bringing value.



Interactive workshop for eighty international executive clients of Coupa Software

“David has a big brain and an innate ability to simplify complex emerging topics. After reading both his books, I knew our clients would benefit. Our clients have attended many special speaking events globally throughout their careers, and so many of them said David’s workshop was one of the very memorable. Everyone at Coupa is very grateful for David’s thoughts, humility and warmth.”


Mark Riggs | Chief Customer Officer | Coupa Software  


Construction and engineering group’s use of technology

“David's work with both the IT and Finance teams really helped these teams refocus on the priorities for the coming year and how the team will work together to deliver these. David was able to create an environment when working with the staff where they felt able to speak openly and honestly whether it be in a one on one discussion or a team-building workshop. This allowed David to extract maximum value from the discussions from staff and document a clear strategy with tangible actions & initiatives for the Finance and IT Teams.


I would highly recommend David for your business.”

“Ever since my first meeting with David Banger, I have been extremely impressed with his prowess as a business advisor. So much so that I decided to engage David to provide the keynote at our company’s recent strategy conference. David was extremely approachable, helpful and collaborative during the planning and preparation phase. On the day, he delivered an extremely insightful and highly motivating address. My team and I look forward to engaging with David in the future. I would certainly recommend David to other business leaders who are looking for an expert, highly relevant and valuable source of thought leadership.”

Technology innovator; DXN’s Sydney data centre opening

“I have had the privilege of knowing David for the past ten years from a very unique position that of being a key supplier partner to David, and as a customer. As a customer, I found that David truly listened to our expectations, tailored, and delivered an approach that added to our event. David communicated very effectively before the event, shared previous experiences for our benefit on the day and integrated himself with ease into our team. He was truly a DXN team member for a day; our team felt and commented on this. His professional experience and ability to communicate with insights are rare.


I would highly recommend David for your business.”
