WHAT IS nessio® ?
DEVELOPMENT BEGINS WHERE RELATIONSHIPS SUCCEED.
nessio® is a RELATIONSHIP–ORIENTED METHOD for the development of people and organizations. It makes visible how individual competencies interact in a personal, social and professional context – and how this DYNAMICS affects the relationship to oneself and to others. This deep understanding enables authentic leadership and healthy relationships: for PEOPLE, through COMPETENCE, with SUCCESS.
Whether in COACHING, in LEADERSHIP or in COLLABORATION – nessio® creates a common language for what otherwise often remains unspoken: Attitude, resonance, orientation. This makes visible where development is possible – and what people need to develop their potential in relationships.

THE nessio® COMPASS
WHERE nessio® CREATES IMPACT.
Personal, personnel and organizational development are complex – and every role in the system has different challenges to overcome. The nessio® COMPASS brings structure to this diversity: it shows FOR WHOM nessio® is relevant – and in which AREAS the method unfolds its potential.
Whether you are shaping CULTURE, leading PEOPLE, supporting TEAMS or developing TALENTS – nessio® is connectable because it speaks the language of every target group. The nessio® COMPASS distinguishes EIGHT TARGET GROUPS in four quadrants. This provides orientation – and a clear view of where and how development works.
THE nessio® COMPETENCIES
AUTHENTIC LEADERSHIP AND HEALTHY RELATIONSHIPS.
What makes people truly effective? Not just knowledge or position – but the ABILITY to lead oneself, to enter into healthy relationships with others and to show the right ATTITUDE at the right moment.
The 12 nessio® competencies form the FOUNDATION of the method. They describe how a person thinks, feels and acts in a personal, social and professional context – and how all of this works in RELATIONSHIP. Individually, they show where POTENTIALS are alive and where development is possible. In a team or company, they make visible what strengthens COLLABORATION – and how tensions can be resolved.
The competencies offer STRUCTURE without typifying – and create a common LANGUAGE for development with substance.
THE nessio® AUTHENTICITY MODEL
INNER BALANCE LEADS TO OUTER IMPACT.
Behavior does not arise out of nothing. There are FORCES at work behind every action – visible and invisible, conscious or unconscious. The nessio® authenticity model makes these inner DYNAMICS tangible: It shows how the nessio® competencies relate to each other, what creates tensions – and how development succeeds from inner BALANCE.
Whether in COACHING, in LEADERSHIP or in CHANGE PROCESSES: the model offers a map for what drives people, slows them down or throws them off balance. It provides orientation – where CLARITY is lacking – and opens up spaces for real development.
THE nessio® ASSESSMENTS
SUCCESS IS MEASURABLE.
“No knowledge without experience. No experience without knowledge.” – The nessio® Assessments make it VISIBLE how people experience themselves, how they affect others and how they move in a professional, social and personal context. Non-judgmental. Differentiated.
Three assessments – many perspectives:
- THE alpha-ASSESSMENT for individual and team coachings.
- THE beta-ASSESSMENT as a 360-degree feedback for Leaders.
- The gamma-ASSESSMENT for Recruiting and Personnel Development.
THE nessio® ACADEMY
PERSONAL. SAFE. CONNECTED.
The nessio® ACADEMY is the place where nessio® can be experienced – as a coaching LOCATION, as a training ENVIRONMENT, and as a FORUM for personal development and collegial exchange. The focus is on the ability to enable development in relationship – with attitude, structure and depth.
The nessio® Academy combines METHODOLOGICAL SAFETY with personal MATURITY – for people who are not just looking for tools, but a sustainable UNDERSTANDING of genuine development.

SEBASTIAN FLECK
ORIGINATOR OF THE nessio® METHOD
I am convinced that CLARITY CREATES SAFETY. There is enormous potential in uncertain or complex situations in particular – if you are prepared to look, recognize connections and create orientation. Because where clarity arises, people can act more confidently, take responsibility and become effective.
As a COACH, CONSULTANT and ENTREPRENEUR, I have been supporting individuals, teams and organizations in change processes for many years, always with the aim of facilitating sustainable SOLUTIONS and thinking development in terms of relationships. With nessio®, I have created a model that combines HOLDING, STRUCTURE and DEPTH – for people who don’t just want to function, they want to WORK.
DAMIANO MARANGI
CO-DEVELOPER OF THE nessio® METHOD
I believe in conscious development – not in quick fixes. “MEASURE 3x, CUT 1x” is more than just a slogan for me. It stands for the attitude of first sensing, reflecting, recognizing connections – and then acting clearly and coherently.
As a COACH, SUPERVISOR and CO-DEVELOPER of nessio®, I accompany people on their path to greater DEPTH, CONSCIOUSNESS and RELATIONSHIP COMPETENCE. I create spaces in which not only answers are sought, but real questions are allowed. nessio® offers what is needed for this: a clear structure – and at the same time SPACE for what lies between the lines.
