past events
- “Their mix of knowledge and energy was contagious, sparking conversation and collaboration from even the quietest in the room. I really loved being able to relate concepts and behaviours to actual personas (which could be related to ones own individual experiences), and delivering in a way that is simple to understand with great impact.”
- “What a great workshop at Product Aotearoa! It was very good and refreshing. I am keen to stay connected!”
- “I attended today the presentation "Agile is Dead. Right?!" by Marcella Koopman and Bartwin van der Pols, from Defiant. Great topic, very informative and relevant to today's job market and of course, great presenters. Thank you both!
- "If you're looking for help with Organisational Change, do reach out to Defiant's Marcella and Bartwin, who gave a fantastic presentation, without the BS!"
