Arie van Bennekum
Although one of the AM founders, his name surprisingly hasn't really touched ground in the Agile movement in Europe. But Arie has a great story to tell: how to get users more involved in projects and how a project (including all stakeholders) can benefit from that. He doens't look at agile from a technical or process perspective, but from tangible results, business cases and value creation. Arie is always 'present'- when he's around people change their perceptions!
