Brussels, Brussels Region, Belgium
Most leadership teams reach a point where the organization stops keeping up with the business. What worked at 50 people breaks at 150. Decisions slow down. Good people leave. Nobody owns the people agenda — or the wrong person does. That's when I get called. I work with founders and executives in companies between 75 and 250 employees as a consultant, as a Fractional HR leader, or as an executive coach, depending on what the moment needs. My entry point is always the leadership team and the organizational question. Over 10+ years as Director People & Culture, I've built HR functions from scratch, scaled organizations through rapid growth, and worked across 5 countries / 3 continents. Some results I'm proud of: → Reduced onboarding attrition from 4% to 0% at EVA Solutions Group GmbH → Supported 100% organizational growth at LeasingMarkt.de GmbH without structural breakdown → Built people analytics infrastructure that gave leadership real-time visibility for the first time I work close to the action. I think in systems. And I say what I see. Based in Brussels. Working with clients across DACH, Belgium, and Luxembourg. → marcomansfeld.com
Vertax is a specialized headhunting firm placing senior talent in Tax and Legal. One of the most relationship-driven and candidate-scarce segments in executive search. Brought in as Interim Chief of Staff to build the operational foundation for scalable growth. Doubled qualified call volume through structural process redesign. Implemented a CRM from scratch and automated critical sales processes, reducing manual overhead and creating full pipeline visibility for the first time. Built a knowledge management system that made institutional knowledge accessible across the team, turning individual expertise into a shared operational asset. Mentored the recruiter team and aligned talent pipeline strategy with revenue targets at the leadership level.
I work with founders and leadership teams in companies between 75 and 250 employees at the intersection of organizational design, people strategy, and leadership development. My entry point is always the same: the moment an organization stops keeping up with its own growth. Depending on what the situation calls for, I work as a strategic consultant, step in as a Fractional HR leader, or coach executives through phases they've never navigated before. Sometimes all three at once. Clients come to me when roles are unclear, leadership friction is slowing decisions, HR hasn't scaled with the business, or the culture they talk about isn't the one they live. I work close to the action, think in systems, and don't deliver slide decks and disappear. Based in Brussels. Working across DACH, Belgium, and Luxembourg. → marcomansfeld.com
