Maarten Kalk

Value Consultant - Associate Partner

A programme and product leader who’s spent thirty years implementing business software and data inside complex organisations, from SAP and ERP programmes across government and global brands to leading data, analytics and AI product teams at Nike. Now with Valliance, he's helping enterprises do the thing most get stuck on, integrating AI into their ERP and data landscape.

Maarten built his foundation in ERP and moved steadily up the stack, from running the transactional systems to unlocking the data trapped inside them, but none of it was ever just an IT project. Each one changed how the organisation worked, and he has always owned that transformation alongside the delivery. Three entrepreneurial ventures and a neuroscience-based training he built for project managers sharpened his feel for the human side of change.
