GmbH ApS
is a boutique consultancy
specialised in company culture.

We work with
business leaders
to align culture with strategy.

We define a company’s culture as its attitude, behaviour and reputation. It is the humane quality of the relationship between the organisation and its community.

A well considered culture informs all of the business’ operational actions and provides the foundation for a genuine and recognisable identity.

The leadership of a progressive organisation recognises that central to its commitment is to provide its employees with a purpose-led work environment, a values-aligned social system, rooted within the people of the organisation.

GmbH ApS offers a combination of consulting and facilitation services including:

Strategic culture change management
B Corp advisory – B Leader
Leadership development
Progressive HR strategy
Stakeholder mediation
People & Organisation advisory

GmbH ApS is led by its co-founders, Mia Castenskjold and Stefan Zschernitz. Over the last two decades, they have both lived in, and worked globally across, many different cultures and industries.

They acquired, along this journey, not only many languages, but also the hard-won knowledge of how to successfully navigate and adjust to different corporate cultures.

As leaders at organisations they have worked to design and build culture practices, policies and programming that serve the whole workplace community.

Their experience has taught them to deeply understand the complexity that organisations represent and they skillfully guide their clients to recognise the power structures and dynamics existing within their organisations. Throughout this process, they enable business leaders to empower their people by recognising their individual strengths, skills and abilities.


To create a company culture that is healthy, respectful and progressive, we believe that trust between people is the vital element.

  1. We trust in kindness and transparency.
  2. We trust in integrity, responsibility and self-management.
  3. We trust in people’s autonomy like we trust in togetherness.
  4. We trust in stability, practicality and functionality.
  5. We trust in culture being lived, not launched.
  6. We trust in treating the cause rather than the symptoms.
  7. We trust in accountability and we trust in positive change.
  8. We trust in science as much as we trust in curiosity for the other.
  9. We trust in diversity, equity and inclusion.
  10. We trust that you will trust us.
