ABOUT

Business strategy and transformation expert, with 15 years’ experience in strategy consultancy (Ex OC&C and EY-Parthenon)

|

Designing and implementing end-to-end transformation for large corporations, addressing their strategic challenges without artificial boundaries, using a modern, smart and pragmatic approach: this is my area of expertise, and it is on this conviction that we founded Constellations

ABOUT

Expert in omnicommerce and data-driven marketing, with over 10 years’ experience in marketing consultancy (Ex BCG)

ABOUT

Investment strategy and due diligence expert, with nine years’ experience in strategy and private equity consultancy (Ex EY-Parthenon)

|

My young children have taught me two things: always ask "why", and never stop halfway. That is the whole spirit of Constellations: understanding quickly, getting to the heart of things, and standing by our clients until their decisions become reality.

ABOUT

Strategy and private equity expert, particularly in the agri-food and B2B retail sectors, following 10 years in consultancy (Ex OC&C and EY-Parthenon).

|

I enjoy complex projects, from strategic planning to acquisitions and their integration. To see them through to a successful conclusion, I become part of the team: I listen, I help clarify options and I facilitate decision-making. It’s an approach I also practise with my three children!

ABOUT

Data and AI expert, with over 10 years’ experience in scale-ups (Ex Google and Artefact)

|

From coding to executive committees, I have worked in a wide range of data-related roles, in environments that are as dynamic as they are varied. The more complex and fast-changing the context, the more I thrive: that’s where data and AI make all the difference. Outside of work, I contribute to the French data scene or go running in the mountains.

ABOUT

Strategy & value creation expert, with 15 years of experience (ex Roland Berger, Estée Lauder and Imker Capital Partners)

|

I enjoy tackling complex challenges, challenging the status quo and inspiring teams to break new ground. After eight years in consultancy and four years in investment funds, I remain convinced that a strategy is only as good as the decisions it enables and how it is implemented on the ground.

ABOUT

Strategy & private equity expert, with 15 years in consulting (ex-EY-Parthenon and Bain & Company)

|

Some fifteen years helping tech leaders and investors shape their growth strategies and investment decisions. What drives me is getting both ends right: the clarity of a bold thesis, and the uncompromising rigour of the detail behind it. Off the clock: lots of sport, and two kids who ask more questions than my clients do

ABOUT

Growth & performance marketing expert, with 12 years of experience (ex Vestiaire Collective and Lazada, Alibaba Group).

|

Growing a business takes more than just a good strategy: execution is just as important. For the past 12 years, this conviction has guided my approach to marketing, by combining strategy, data and AI. I enjoy challenging assumptions, experimenting and turning ambitions into tangible results. And I never turn down a game of chess!

ABOUT

Transformation & operational performance expert, with nearly 15 years in consulting (ex Orphoz, a McKinsey company, Deloitte and Sia Partners)

|

I support senior management and their teams with their transformation, organisational and change management initiatives. On a day-to-day basis, I really enjoy working with operational teams to help them make progress and contribute to solving their problems.
