Leadership consulting

International Center for Executive Options (ICEO®)

Our International Center for Executive Options (ICEO®) advises senior business leaders around the world about how to navigate leadership changes and transitions and advance their professional goals, brand and legacy by opening doors to new possibilities. 

Whether it’s due to a change in strategy, the need to make room for emerging leaders, or the desire to follow a personal passion, there comes a time when senior business leaders need to move on. 

Those who leave your organization with dignity and the support to advance their careers are much more likely to serve as valuable brand ambassadors. They’ll pass on vital knowledge to remaining leaders, and help successors maintain strong client relationships.

We surround leaders with a dedicated team of senior experts and peer advisors to offer the most comprehensive experience in the industry, including:

  • Assessing different professional options including; traditional corporate roles, venture capital and private equity roles, entrepreneurship; board service, and portfolio careers (combining part-time board service, advisory, and consulting).
  • Introductions to fellow industry leaders, executive recruiters, private equity firms, venture capitalists and ICEO® alumni.
  • Access to ICEO® advisors in 20 business centers around the world.


Lee Hecht Harrison®'s ICEO® center has developed into a first rate resource for high level professionals in transition. Lee Hecht Harrison now provides world class support for this level of executive, surrounding clients with competent, available experts who quickly put me in a position to approach the market in a focused, confident and prepared manner. It is no coincidence that I quickly found an exciting, rewarding position as a General Counsel in a talented biotech company that fully matched my hopes and expectations.
