To me the most important roles as an ally are to be vigilant, observe and speak up if one sees discrimination, to take an interest for the different communities and to become a role model for others to follow.
For those interested in exploring entrepreneurship as a career path, I highly recommend you roll up your sleeves and actually try to build a real startup during your time at INSEAD.
After 10+ years working in the finance industry and with the goal to deepen my knowledge, the EMFin programme is the one that adequately satisfies my goals.
Part of the reason why we embark on such a programme is to network with people outside of our existing social circle, to exchange ideas and to learn more about the broader finance field.
