Manage transition and extra workload

Part time or full time
Recognizing that not all roles necessitate a full-time consultant, Altesia provides flexible staffing solutions tailored to your exact needs. Our consultants (payroll or interim managers / freelancers) are available to assist you for the time needed, from 1 up to 5 days a week, ensuring you receive the exact right level of support: no overselling or underdelivering
Several expertise levels for one full-time equivalent
Several expertise levels for one full-time equivalent
For missions demanding specific expertise or a blend of senior and mid-level skills, we provide a collaborative, flexible and budget-friendly approach: an interim manager such as a CFO, Procurement Manager or Human Resources Manager, or even an Altesia Partner, can team up with the consultant.
This combination ensures that you receive both high-level expertise while maintaining operational consistency and long-term execution. This means that you get varied levels of expertise for the budget of a single full-time employee (FTE).
This efficient approach eliminates the need to hire an overqualified executive for day-to-day operations and avoids the unnecessary expense of employing two full-time professionals when the workload doesn’t require it.

What our clients say
-
Thibaut Devroye Group Accounting & Consolidation Manager, EliaWith Altesia, we didn’t just get a consultant: we got a structured, high-quality approach that truly makes a difference.
The 3 consultants we worked with delivered excellent results, but what stood out was the way they were coached and supported. Altesia’s reporting method and regular partner touchpoints brought clarity, discipline, and follow-through to every task. -
Didier De Vos SVP EMEA Service & Solutions, GloryEvery profile Altesia proposed was spot on, operational, reliable, and adapted to our complex environment. In less than a week, I had someone in place: skilled, available, and ready to take over. That level of responsiveness made all the difference.
-
Mohamed Ahmaidi Controlling Manager, LavafieldsThe Altesia consultants I’ve worked with have always been people who adapt quickly, listen, understand our environment, and move things forward without ever pushing their way through. Their screening process is clearly rigorous: the technical skills are there, of course, but what truly stands out is their emotional intelligence. Their consultants know how to integrate seamlessly, read the room, and adjust their approach. That makes the difference.
-
Alexandre Richel CFO, MonizzeAltesia’s added value is the follow-up. The consultant isn’t left on their own, and I have a trusted partner I can call whenever I need expert advice. I don’t just get a consultant, I also get access to the partner, who acts as a sounding board for more strategic topics.
-
Nicolas PutzeysWhat really stood out with Altesia was the value for money and the quality of execution. The consultant was hands-on from day one, backed by a partner who clearly followed the mission closely and stepped in with senior expertise whenever needed.
Everything was structured, monitored, and transparent. I could see the detailed follow-up, even when I didn’t have time to look myself. And above all, their approach was truly practical: no glossy slides, just sleeves rolled up and real work that moved things forward. The perfect mix of impact, senior insight, and efficiency.
