Small Giants about working with Bart
'Working with Bart is really enjoyable. Fun and high-impact. He connected with every discipline — from C-level to logistics — and navigated the international context with ease. He went beyond what was asked and consistently elevated both culture and results. A concrete example: he booked strong results with Zalando across Europe. He understood the dynamics fast, took ownership and kept momentum high.'
