At GECOS, we focus on quality, practical solutions, and lasting impact. We are a boutique consultancy that partners with leading organizations to achieve sustainable success—and many of our clients have trusted us for over a decade.

Our approach? Theory alone doesn’t change anything—what matters is what works in practice. That’s why we rely on concrete, actionable methods and tailor-made programs in leadership development, change management, and team development. Instead of abstract concepts, we deliver practical solutions that turn knowledge into measurable results.

Our consultants bring years of hands-on experience from corporate and organizational settings and serve as trusted sparring partners to our clients. We believe that excellent leadership is built through experience, the right mindset, and consistent practice. That’s why we help leaders unlock their potential, increase their impact, and drive long-term success—using innovative methods, interactive training, and genuine commitment.

Hosam Ghadamsi, Managing Partner

I’m a consultant and coach by heart – driven by the goal of supporting people, teams, and organizations as they grow and evolve. My journey has taken me through diverse professional and academic experiences that have shaped how I view leadership and collaboration today.

After studying mechanical and aerospace engineering at Princeton University and completing postgraduate studies at Imperial College London, I gained international corporate experience with companies like Mars Inc., working In many different departments such as Production, Sales, Marketing and HR.

But what’s always fascinated me most are the people behind the structures. That’s why I’ve deepened my expertise over the years through systemic consulting and coaching qualifications – and placed my focus on leadership and team development.

Born in Tripoli, raised in Vienna, I bring an intercultural perspective that strongly shapes my work. Connecting different ways of thinking, creating new perspectives, and driving meaningful change – that’s what motivates me.

For me, it’s never been about abstract frameworks – it’s about practical, human-centered solutions that actually make a difference.

Diana Resch

„Only what we recognize and name within ourselves can we consciously shape and develop in the external world.“

I found my way into management consulting via side roads – career stops that have had a lasting impact on me. The constant question that always accompanied me was: How do we humans actually function? What do we specifically need in today’s working world, which is currently being reshaped under the influence of technological upheavals, geopolitical uncertainties, and ever-increasing information density?

After ten years in healthcare, I studied psychology and entered the business world, where I took my first job as an industrial and organizational psychologist at an international engineering company. It was there that I realized that the boundary does not lie between humans and machines, but within people themselves and between them: raising the question how do we create organizational structures to shape collaboration, build trust, and create meaning.

For me, developing psychological competence is the invisible architecture of any profound organizational development: this became clear to me during my systemic consulting and coaching training.

I am passionate about self-leadership, which can be developed not only individually but also collectively within an organization: building resilient teams, establishing an adaptive leadership culture, and empowering each and every employee—because the real source of productivity lies within us.

Gottfried Hündler

I help executives and entrepreneurs boost their personal productivity in business, thereby freeing up more time for what really matters.

By focusing on key priorities and their personal strengths, they discover first-hand how they can simply get more done – and in doing so, drive their teams and their organisations forward in the long term. I have developed the 5-step productivity plan as a foundation for this.

As a long-standing manager at a leading global manufacturer of branded goods, I have gained extensive experience with international clients, complex projects and the management of numerous staff members. In more than seven years as a management consultant specialising in productivity, time and process management, I have supported many managers and entrepreneurs in taking their own productivity and that of their companies to the next level.

In addition to my studies at the Vienna University of Economics and Business, a study programme in the USA and Asia, and a technical college (HTL) course in industrial engineering, I taught at the University of Applied Sciences in Wiener Neustadt for eight years.

For me, the focus is always on the individual and the challenges they currently face. The better I understand the situation, the more effectively I can support managers in utilising their strengths in a targeted manner and achieving systematically measurable results – that is precisely what I am passionate about!
