Prisma.M was founded by Mattijs Messely, a policy maker and trainer with several years of experience in inclusion and diversity, strategic management, client-focused consultancy, and organisational development.

You can turn to me for:

  • Consulting services

  • Organisational development

  • Training

Together, we explore the best way to map and address the needs of your organisation. You can count on me to approach this from:

  • Design principles. By daring to innovate, working with various methodologies, and continuously improving, we create sustainable solutions for your operations and services.

  • Cooperative working. I can help you work with all relevant stakeholders to achieve clear and concrete interventions.

  • Developing leadership competencies through training. Navigating a diverse society or organisation as a leader is not straight-forward.

Are you ready to create impact together? Get in touch to find out what I can do for your organisation.

Services

Consulting

You can rely on me to deliver tailored solutions and to think in terms of your needs as a client. Together, we determine the scope, timeline, and objectives of the assignment.

You can involve me at any stage of a process or project to add value. Conducting an audit of your existing operations and services is also possible.

Prisma.M works with both non-profit and commercial organisations across Flanders, Brussels, and the Netherlands.

Organisational Development

With me, you won’t receive a one-size-fits-all checklist or a rigid approach that doesn’t fully align with your needs. I work transparently and can flexibly navigate various methodologies.

Together, we ensure results that are sustainable and future-proof. You can count on me to work on your organisational structures, culture, and leadership competencies.

Training

Thanks to my experience in inclusion and diversity, you can turn to me for a wide range of one-off workshops or tailored training programmes. Feel free to get in touch to discuss the options.

In the spring of 2026, I will launch an open programme of workshops for HR professionals, managers, and policy advisors. You can find more information under ‘Training’.
