Synthesis has a Leadership Assessment tool developed by experts in the Israeli Defense Force, Executive Coaches, and one of the foremost talent search companies in the world.

We believe that businesses and elite military units have a lot in common –  the risk and reward, the critical need for the right people to be set up for success, and the importance of unit leaders having the information they need to operate well. Collectively, we have created value for thousands of companies by discovering what matters most to the individual and the company, defining experiments, and implementing action plans.
