Strat for impact.

The firm that challenges convictions

Circle Strategy supports top management in their challenges with its specific pragmatic approach. The Circle Strategy approach comes from the unique profile of its 50+ Circlers, all having strategic consulting experience and hands-on entrepreneurial and/or company experience.
Our motto, ‘Strat for impact,’ reflects our commitment to putting strategy at the service of bold and sustainable futures.
Circle Strategy was founded in 2019 by three entrepreneurs convinced that strategic consulting must evolve to address today’s fast changing business environment.
Part of Square Management, the firm is now present in Paris, Brussels, and Luxembourg, with projects spanning the globe (e.g., USA, Nordics, India).

  • Brussels: 17 Blvd Général Wahis, 1030 Brussels, Belgium
  • Paris: 31 rue des Poissonniers, 92200 Neuilly-sur-Seine, France
  • Luxembourg: 155 rue du Kiem, 8030 Strassen, Luxembourg


The driving force
of modern
strategic consulting.


To adapt to the fast-changing business world, we believe that strategic consulting needs a new approach. The old ‘one-size-fits-all’ model no longer works. Our focus is on making decisions that match a company’s legitimacy and are carried out effectively by our team of experienced experts (see our profiles section).

Our pragmatic approach is summed up in 4A:

  • Acceptability
    Active engagement of all stakeholders to ensure their commitment.
  • Applicability
    Tailored recommendations designed to be successfully implemented.
  • Agility
    Flexible recommendations to thrive today’s constantly evolving environment.
  • « Accountability »
    Our unwavering commitment to ensure that our recommendations have a positive impact on business models, society, and the environment.


We craft strategies for
bold and sustainable futures.


The best strategy isn’t necessarily the smartest, but the one generating the most impact.
Circle Strategy ensures that, every day, on every project, we deliver a triple positive impact in terms of:

  • business model
  • organization
  • social and environmental responsibility of the company

Let’s ensure a bold and sustainable future together.
