Quartet Consulting creates and advises on strategy, content and implementation for ultra-high net worth individuals, luxury brands, major infrastructure projects and private family office investments around the world.

In a world where key directions in politics, economics, commerce and leisure are made by the “zero point one per cent” of global influencers, we have an inside understanding of this sector. We are not just ahead of the curve: we help create it.

Our core operation draws on the skills and talents of leaders in their fields, according to each client’s vision.
