Mars & Co was founded in Paris in 1979 by Dominique Mars on a conviction that was radical then and remains rare today: a strategy consulting firm should serve only one client per industry, worldwide, without exception. That founding principle — firm-based exclusivity — has never wavered. From our first office in Paris to seven offices spanning New York, San Francisco, London, Tokyo, Shanghai, and Singapore, every expansion has been made in service of the same goal: bringing genuine competitive leverage to a deliberately limited number of clients, and serving them with the depth, fidelity, and consistency that only a firm built this way can offer. Today, with more than 100 consultants operating as a single global practice — never a collection of office-based fiefdoms — Mars & Co remains the only consulting firm of global scale to guarantee true exclusivity to each client it serves.

Mars & Co is a team of roughly 100 consulting professionals who operate with a philosophy that sets us apart from the industry: our senior people are not rainmakers or presenters — they are player-coaches, working at the elbow of clients and leading teams through the hardest problems in business strategy. Our professionals are recruited from the finest universities and graduate schools across the globe, selected specifically for quantitative and analytical excellence in fields such as engineering, mathematics, economics, and the physical sciences. We promote exclusively from within, developing every senior advisor through our apprenticeship model — where junior consultants learn by doing, mentored directly by some of the most experienced business strategists in the world. The result is a firm where analytical rigor, intellectual honesty, and practical problem-solving are not aspirations but daily practice, at every level.

We help our clients realize the full potential of their businesses through Business Strategy, Operational Strategy, and Strategic Advisory. Whether the challenge is achieving a world-class cost structure, identifying and capturing the most promising growth opportunities, reshaping a business portfolio for lasting strategic advantage, or building the capabilities needed for ongoing success, Mars & Co brings a rigorous, fact-based analytical approach to every engagement. We build the most robust fact base available, apply creative and continuously evolving analytical frameworks, and deliver customized insights — not generic industry templates, not untested opinions. Every recommendation we make is meticulously supported by solid evidence and tested against skeptical inquiry, yielding specific, bankable action plans that our clients can execute with confidence. When our analytical tools are combined with a client's own operating knowledge, opportunities are unlocked that neither side would have found working alone.

Our goal is unambiguous: to make our clients stronger, more profitable, and better positioned than all others in their respective fields. Mars & Co exists to help the world's leading organizations unlock the full potential of their businesses — not by producing reports or generating opinions, but by building durable business value through analysis that is rock-solid, insights that are genuinely new, and solutions that are both practical and proven over the long term. We measure our success not by the volume of engagements we take on, but by the depth of the competitive edge we deliver to the select few clients we choose to serve. That singular focus on client outcomes — and the trust it has earned across decades — is the raison d'être of everything we do.

Six principles have guided Mars & Co since 1979, and not one has been compromised in the decades since. In-depth analysis is the foundation of everything: we stake our reputation on world-class analytical capabilities, going far beyond what other firms typically achieve — 'mile-wide-and-inch-deep' approaches are simply not in our DNA. Firm-based exclusivity ensures that our interests are always fully aligned with those of our clients, with no conflicts of interest, ever. WYSIWYG — what you see is what you get — means our senior leaders are in the trenches with clients, not in the boardroom selling. The 'family outsider' relationship we build with clients is one of genuine trust and confidentiality, made possible only by the exclusivity we guarantee. A versatile toolkit of continuously refined methodologies allows us to craft solutions that fit each client's unique situation, not pre-packaged answers. And the margin of difference is our ultimate measure: we exist to give already-successful leaders the edge they need to stay decisively ahead of their rivals.

In strategy consulting, superior bottom-line results come down to three things: people, tools, and experience. On all three, Mars & Co is built differently. Our people are in-the-trenches consulting professionals — not sales figures — who coach and lead teams using facts, not opinions, to drive decisions. Every recommendation is grounded in quantitative rigor and backed by meticulous evidence. Our tools are proprietary, continuously developed and enhanced by senior leadership, and deployed in a customized and integrated fashion — never off-the-shelf, always tailored to the specific situation. Our experience spans decades of working as strategy generalists across many industries and geographies, giving our professionals the diagnostic speed and pattern recognition to rapidly identify what is really happening in any business situation, anywhere in the world. Add to this the continuity and trust built through long-term, exclusive client relationships, and the result is a depth of partnership — and a consistency of product quality — that clients consistently rate as superior to all other firms.
