I have learnt a lot from Dave over the years. There is a sharpness about him and a vision when he talks on 'business' (mobile, social, blockchain, entrepreneurship etc) which is powerful and interesting. But he also enjoys the ‘wider’ conversations about intellectual matters and matters of the heart and soul. It is this very contemporary mixture of a purpose-driven, value-central life and seeking a way to survive and flourish through work and in relationships which makes Dave someone I am always happy to work with. He is a subscriber to the belief that life, ultimately, is about learning.
