We have led inside global corporations and we have built, bought and sold companies of our own. We advise from experience, not theory.

​Sébastien works with executives and senior leadership teams to build the decision discipline, alignment and operating rituals that turn strategy into consistent results.

He has more than 20 years of international experience across Europe and Asia. He held executive positions at Burberry and has worked alongside leadership teams at LVMH and Richemont, in luxury, high watchmaking and technology, some of the most demanding operating environments in global business.​

 

At Whysebird: he leads every client engagement and brings that operational standard into the client organisation. He works inside the team, not as an outside observer, because he has carried the same weight his clients carry now.​​

Alexandra has run, bought and sold a company, and brings that CEO and shareholder view to the team.

A veterinary surgeon trained at the Toulouse Veterinary School, she joined a veterinary biology laboratory in 2001 and became a partner in 2008. In 2013 she bought it out on her own through an LBO. She then structured and grew the business before selling it in 2022 to a group building a multi-site veterinary biology hub in France. She has 23 years in the field and holds an MBA.

​

At Whysebird: she helps CEOs and leadership teams find what really creates value in their organisation and turn it into results. That means operational performance, service quality, reputation, and a stable, committed team, delivered for shareholders, employees and clients alike.​

Leslie works with companies entering or growing in the French or UK market that need to adapt how they explain, sell and build trust locally.

Entering a new market is rarely just a translation problem. It’s about what buyers expect, what earns credibility, which proof they need, the words used in the category, how decisions get made, and whether the company is clear internally about its own message.

​

At Whysebird: she helps leadership teams carry their strategy across borders, aligning their message, sales approach and client experience with the market they want to win.

Alexandre has spent 20 years leading business units and SMEs of 40 to 300 people. He has handled company creation, takeovers, restructurings, changes of shareholder, fundraising, sales, hyper-growth and major crises.

In 2012 he took over an SME, transformed its culture and organisation, and passed it on in 2023. He created the CLOSER Organizational Performance® approach. His work draws on group and individual psychology (Berne’s organisational theory, transactional analysis), Vincent Lenhardt’s coaching methods, and Total Quality Management, Lean and Agile.

​

At Whysebird: he works with CEOs and their teams on organisational change, combining hands-on management experience with a structured understanding of how people and groups behave.

François turns complex systems into models that leaders can make decisions with.

He trained as an engineer: classes préparatoires at Lycée Stanislas, a master’s in civil engineering at ESTP, and a master’s in engineering management at the University of Melbourne. He began his career at Accenture, advising industrial clients worldwide on productivity, cost and operational resilience. From 2018 to 2021 he led Make Fashion Circular at the Ellen MacArthur Foundation, where he built quantitative models of the circular economy opportunity and operational frameworks adopted at scale. Today he leads quantitative climate-economic analysis for industrial and institutional clients at Swanstant, and sits on the SMEP Independent Technical Advisory Panel.

At Whysebird: he brings analytical rigour to client work, using models and data to frame decisions and make results measurable.
