Leadership

Winterhawk is not your typical consultancy service.

We have been ‘the customer,’ responsible for delivering enterprise-wide solutions and services; we have managed budgets and presented to executive committees, and that’s what sets us apart. Because our senior leadership can relate to your challenges, Winterhawk offers more than a conventional consulting service. We will work with you and support you through every stage of your project.

Our growing Advisory Board consists of telecom and financial services CEOs, seasoned sales and financial executives, who provide key insights and strategic advice.
