Our vision

marbl combines years of experience and expertise in strength-based development. Imbued in our belief in the power of positive psychology, we always start out from the belief that every behaviour that manifests itself in an organisation fundamentally originates from a positive intention. We bring things into the consciousness and moderate how to translate them into results, based on the rock-solid conviction that the potential already intrinsically exists.

We allow room for experimentation and progress in stages. Growing is daring to deviate from the usual path, but also getting the space to work in a creative and safe environment where every idea is basically a good idea. Learning and growing form a continuous process. Every advance is a step in the right direction deserving of recognition.

Our team

Katrijn Steenbeke

Founder & corporate positivity® activist

I am firmly of the view that everyone has beautiful qualities in them. I see it as my true purpose in life to help people discover these qualities, on which they can rely to find happiness at work and in life.

More

My setting up marbl is a logical consequence of this, which allows me

to translate this conviction into reality. In doing so, I’m so bold as to differentiate myself and to do things differently in order to achieve ground-breaking results in the field of positive leadership and organisational culture. In this, corporate positivity® is our registered model and our method for a breath of fresh, positive air in organisational cultures.

My thirst for discovering the world and learning from different cultures has shaped my rich international career. I can rely on profound knowledge and a wealth of insights into development, leadership, organisational culture, sales and communication, thanks to a career spanning many industries.

I’ve led senior management teams, designed and implemented sales and HR strategies, developed learning environments and facilitated leadership processes. I’ve supervised transitions based on both my experience and the knowledge I’ve gained by travelling around the world and through my MBA in international project management.

As a mentor and coach, I work with scientifically substantiated strengths- and people-oriented coaching: a methodology that encourages deep learning and effective functioning. The starting point is to align with ideals and core qualities and to deploy them consciously, as well as becoming aware of and overcoming internal obstacles.

Speaking of qualities, I’m proud to share mine, based on CliftonStrengths from Gallup.
🌈 INPUT – I have an unquenchable desire to know more and I enjoy sharing stories
🌈 WOO – I’m energised when I meet people who come with real interest in others
🌈 ST RAT EGIC – I keep abreast of my area of interest and generate ideas and ways of easily advancing
🌈 POSIT IVIT Y – My enthusiasm is contagious and my positive attitude energises the people around me

In addition, I’m a proud mum with two great daughters and have a real passion for Asian history, culture and cookery. I get a real lift from anything Japanese.

That’s me in a nutshell.

Ann Sophie Deprez

Founder & corporate positivity® activist

It feels like a true purpose to support people to discover the power of positive psychology so that they can deal with opportunities, challenges and difficulties in life.

More

When marbl was founded, my dream of becoming an entrepreneur became a reality.
Working on leadership and evolving organizational cultures is fundamental to me if we want to ensure well-being, energy and motivation of everyone.
With this conviction, corporate positivity®, a registred model and method, is a strong answer to let people thrive in any organization, in any context.

I rely on a in-depth knowledge and a wealth of insights in leadership. During my professional life I have been grateful to lead senior management for many years. Being result and human oriented has always been key in my approach.

As a Certified Coach, I work on the basis of strength-oriented coaching which combines different elements from various approaches into a methodology that encourages deep learning and effective functioning. The main principle is to bring people into motion directed by thinking, feeling and wanting. This approach is scientifically based.

I like to share some of my qualities based on CliftonStrengths by Gallup
🌈 LEARNER; I love to learn, energized by the steady and deliberate journey
🌈 POSITIVITY; generous with praise, quick to smile and always on the lookout for the positive in each situation
🌈 CONNECTEDNESS; things happen for a reason, I’m sure of it
🌈 INDIVIDUALIZATION; intrigued by the unique qualities of each person

Mindfulness and meditation have found their way into my life since many years.

This was his inspiration for setting up Hello Customer in 2014, which applied innovative technological methods to market research. Hello Customer creates a technology sold to business as Software as a Service – the company operates in Belgium, the Netherlands and France. In 2020, Bram De Vos was made Chairman of the Board of Directors.
