What participants say about us

Good combination of theory & practice. Nice to work on several concrete ideas and to spar with "like-minded peers". Applying theory hands-on to concrete topics. Highly recommended!
Toon Torfs
—Innovation, Business Development & Sustainability at Schoenen Torfs
Very satisfied because the theoretical presentation was followed by an example (in group) in practice so your knowledge sticks for future projects. Cosmos was great at working out cases, in their interaction & communication, explanation of examples from own experiences and in providing a mixture of participants & branches.
Amelie Withaeckx
—Project manager Business Development & Innovation bij Solucious
Hanne and Frederik guided us through the up to then “experiment’s maze” with mastery. By sharing their extensive experience & applying the theory on the spot, I have learned how powerful and important an experiment setup is. The most significant learning for me was how to tie up different experiments, as the sequence of experiments gives us the confidence to say that a hypothesis is validated.
Daniel Bastos
—Transition Management and Ways of Working at Nike
I am a big proponent of learning hands-on. They have perfectly combined this with theory and provided interesting tools. You are never alone in the exercises. There is always someone ready to help you back on your way. A very instructive masterclass that creates a safe space for all your questions and comments.
