At Bain & Company
I can say with great sincerity that he was the best CEO I’ve had the opportunity to work with. Jan’s clarity of vision, thought, and strategic focus, along with exceptional leadership skills and team building were the cornerstone of building the organisation.
He led with trust, clarity and integrity, which is evident in the company culture he helped to create and which remains. … His ambitions led the corporate expansion, his creativity led to new products, his vision led to high-level strategic partnerships.
In my 25 years in the industry, I have never come across a CEO who cared about the business, the product and the technology as deeply as Jan.
Ten years at Bain & Company in Zurich, Johannesburg and New York. Then eight years as CEO of ASMALLWORLD, turning a loss-making social network into a profitable luxury travel group, with three acquisitions and a direct listing on the SIX Swiss Exchange. Today I work independently through JVL Consulting, as an advisor or interim CEO, on select mandates where I can create real value.
I work for owners, boards and leadership teams. Based in Zurich, having lived on four continents.
Tell me about your situation in confidence, and I will get back to you personally to discuss how I can best help.
