Speaking & Lecturing

Gareth Tennant has delivered speeches, workshops and lectures at a number of renowned universities, think tanks and conferences. He uses thought-provoking correlations between global security challenges and those faced by business in a highly de-centralised, complex and connected environment. Gareth’s use of visceral examples, from the world of human conflict and espionage, captivates audiences. He has a unique ability to ground often ethereal ideas into a real-world context; his message is both fascinating and inspiring; it has also never been more prescient and provides fundamentally practical and applicable solutions.


Business Training: Decision Advantage provides both a range of business training and mentoring services from implementation of some quick and simple methods for creating team resilience and  increasing efficiency, through to bespoke scenario based war-games for stress testing.


Let’s build something together.
