LEARN MORE

Circle Strategy supports executive teams in tackling their strategic challenges through a distinctly pragmatic and impact-driven approach.

Our consulting strength lies in the unique background of our Circlers, all combining strategic consulting experience with hands-on operational and/or entrepreneurial experience. Our motto, “Strat for impact”, reflects our commitment to place strategy at the service of bold, tailored, and sustainable futures.

Founded in 2019 by three visionary entrepreneurs, Circle Strategy emerged from the belief that strategic consulting must reinvent itself to meet the complex challenges of our time.

The firm operates globally from its offices in France, Spain, Belgium, and Luxembourg:
– Paris: 173 Avenue Achille Peretti, 92200 Neuilly-sur-Seine
– Madrid
– Brussels: 17 Boulevard Général Wahis, 1030 Brussels, Belgium
– Luxembourg: 155 Rue Kiem, 8030 Strassen, Luxembourg

“I chose Circle Strategy for their pragmatic and highly operational approach. Their teams bring real-world business experience that saved me valuable time. They are solution-driven and deliver results at record speed—a true powerhouse of operational intelligence!”

Antoine Borde
CEO, LIGHTBOX (DE BEERS)

“The challenges I entrusted to Circle Strategy were complex, often unconventional, and always strategic for a business that drives the bulk of BIC Group’s profits.

What set them apart was their ability to fully immerse themselves in the issues at hand, combining a strategic vision with a hands-on approach, honoring the past while building the future, and mobilizing the entire team—including Jean-Marc Liduena—whenever critical issues arose.

All of this was delivered with a collaborative style that was simple, direct, and warm, fostering open communication at every level. My sincere thanks to the entire team, and to you, Jean-Marc.”

François Clement-Grandcourt
CEO, BIC LIGHTERS

“To stay competitive, research centers must evolve rapidly in both technology and funding strategies. Circle Strategy opened our eyes to these new dimensions by enabling us to forge partnerships with key decision-makers in the French and international private sectors.”

Dr Serge Picaud
CEO, INSTITUT DE LA VISION

“I have worked with Circle Strategy on multiple projects across Danone’s AMEA region. I have been impressed by the quality of their team and its ability to connect seamlessly with our local teams and collaborate as one, truly hands-on.

Circle Strategy is deeply committed to creating value by challenging the status quo and bringing fresh perspectives, while always ensuring tangible impact through a focus on concrete outcomes and capability building.

Personally, I appreciated the strong involvement and commitment of Jean-Marc Liduena to secure the success of our projects from start to finish.”

Christian Stammkoetter
CEO, DANONE AMEA — CEO-elect, GIVAUDAN

“I entrusted Circle Strategy with supporting our organization’s transition from a country-based model to a business unit-based model. I was thoroughly satisfied with their work.
First, the quality of their communication: a competent, attentive, and flexible team that never attempted to impose a predefined model—something I’ve found larger firms often lack.

Second, the trust-based relationship established with the Partner in charge, which extended well beyond the assignment itself.

Finally, the quality of the deliverables. Eighteen months after the project’s completion, 90% of the recommendations had been successfully implemented. I would not hesitate to work with Circle Strategy again.”

Lionel Grosclaude
CEO, FIME
