Our Story & Mission
Built for
ambitious
organizations
Artemis Consulting was founded in 2009 by a small team of former strategy executives who shared a single frustration: the world's largest consultancies had grown too large, too process-bound, and too removed from the clients they served. They believed something better was possible.
What began as a boutique strategy practice in New York has grown into a globally recognized firm with offices across three continents — yet we have never lost the founding conviction that every engagement deserves the undivided attention of our most experienced minds. At Artemis, senior partners lead every project. There are no hand-offs to junior teams, no templated deliverables, no billable-hour padding.
Our mission is straightforward: to help ambitious organizations navigate complexity, seize opportunity, and build the capabilities they need to lead in their industries — not just for the next quarter, but for the next decade.
What We Stand For
Integrity
We tell clients what they need to hear, not what they want to hear. Our counsel is grounded in evidence, free from conflicts of interest, and delivered with the candor that genuine partnership demands. Our reputation is built on trust — and we protect it absolutely.
Rigor
Every recommendation we make is stress-tested against data, competitive reality, and operational feasibility. We do not traffic in frameworks for their own sake. We pursue the most accurate answer to the most important question — and we do the work required to find it.
Partnership
We embed ourselves in our clients' organizations, learning their culture, their constraints, and their aspirations. We measure our success not by the elegance of our slide decks but by the durability of the change we help create — together, as true partners.
Impact
Strategy without execution is fiction. We stay engaged through implementation, ensuring that the insights we develop translate into measurable, lasting results. Our clients don't just receive a report — they gain a competitive advantage they can sustain.
What Sets Us Apart
The boutique advantage at global scale
Larger firms offer breadth. Artemis offers depth. While generalist consultancies rotate through hundreds of clients with standardized playbooks, we maintain a deliberately selective client roster — ensuring that every organization we serve receives the full weight of our expertise and attention.
This model attracts a different kind of client: leaders who have outgrown generic advice and are ready for counsel that is as specific, sophisticated, and demanding as the challenges they face. If that describes you, we should talk.

Our Reach
A global firm with a boutique soul
Our six offices span four time zones and three continents, giving us the geographic reach to serve multinational clients while maintaining the cultural fluency that local presence demands. Whether your challenge is headquartered in Manhattan or Singapore, Artemis brings the same depth of expertise to your door.
More importantly, our global network means that when your challenge requires cross-border insight — regulatory, competitive, or operational — we draw on a team that has genuinely lived and worked in those markets, not one that has merely read about them.
