Transforming French Basketball Leagues into Cultural Icons

France is a powerhouse for basketball talent. After Canada, it’s the country that sends the most players to the NBA. Yet, its national leagues — Betclic Élite (formerly Pro A/Jeep Elite) and Pro B — don’t get the recognition they deserve.

Managing change as part of a major rebranding project (AccorInvest becomes Essendi)

Essendi (formerly AccorInvest) reinvents itself with ELEF: new brand image, content, and roadshows to engage 25,000 employees.

What our clients say

( 5/01 ) “I’ve been working with Mathieu for over six years, and he’s far more than a consultant. He operates as a shadow member of our governance, consistently helping us drive forward our most ambitious ideas—even in highly complex environments. His strength lies in turning vision into tangible impact without ever compromising the original power of the idea. He’s a strategic and creative ally, essential when it comes to leading deep brand transformations."

( 1/15 ) "ELEF is more than a creative partner — they are true friends of the House. Their commitment matches their creativity, and together we brought to life bold expressions like The Drop and the reinvention of our brand guidelines. With ELEF, every idea becomes a statement."

Frequently asked questions

Questions you may want to ask before working together.

Still have a question ?
 

What makes ELEF different from a traditional consulting firm?

ELEF merges high-level strategy with deep execution expertise, ensuring that positioning and narratives aren’t just theoretical but drive tangible influence and results.

 

Who do you work with, who are your clients?

We advise companies looking for a narrative and graphic vehicle to support their growth. But our clients are also brands that are seeking or need to reinvent themselves in a turbulent market in order to return to success.

 

What does ELEF stand for?

ELEF is a contraction of the Greek word ἐλευθερία, eleuthería *\e.leu̯.tʰe.rí.aː\ meaning freedom. This freedom to act, to undertake and to succeed is a paradigm that applies to us and to our customers. And a little secret: it's also the founder's first name...

 

How much does it cost to work with you?

We've set up a pre-estimate tool on our website to help you see things more clearly. Our fees can be linked to a single assignment or to more comprehensive support. Prices are based on the impact of the deliverable on the company's performance and the time spent on it.

 

Why should I come and see you and not an expert on the subject that concerns me?

There's nothing to stop you seeing an expert to answer your question. At ELEF, we challenge the problem and the first response is often to reformulate the question. What's more, our strength lies in our ability to bring together the best experts in the field to harness the power of collective intelligence, quickly and cost-effectively.
