PACTUM is Latin and stands for agreement or convention. We all make agreements every day. Private and business. Good agreements are made by talking to our counterpart at eye level. We negotiate. For us. For others.

I would like to support you in this!

Who I am?

Portrait Lisa Kohlrusch

Hey there, I am Lisa Kohlrusch.

My credo: Change. Negotiate. Trust.

Our world of work is changing at a rapid pace. Conflicts arise in the process. We negotiate with each other to make things positive. My experience: If you meet at eye level and build genuine trust with your counterpart, you will find good solutions even in difficult situations.

As an expert in negotiation, communication and conflict management, it is my motivation to support you in making sustainable agreements in your everyday work. So that you achieve the best possible results for yourself and your work.

Are you facing an important negotiation or are you in the middle of a conflict? Let us work together to make things positive.

How did I get here?

For the last five years I have worked as a management consultant in the financial and energy sector. There I have led international negotiations for DAX30 companies and other international players in the context of various major projects. Here I learned early on what it means to conduct negotiations at top management level in a confident and goal-oriented manner. I also learned how to build trust in negotiations and overcome difficult conflicts.

At the same time, as an advisor I also saw a world in which power and economic success were often placed above values and people. I realised that I wanted to be part of a business world where we are allowed to be human beings and where our values and needs are the focus of our daily work. In order to be able to shape my personal working world myself, the step towards being self-employed was therefore obvious.

Today I successfully use my wealth of experience as a negotiation expert. I accompany my clients throughout the entire negotiation process – either in the background or at the negotiating table – and support them in reaching a strong agreement.

Always finding the right balance between assertiveness and a value-oriented business relationship is particularly important to me.

The foundation of my work

  • Experience as management consultant for DAX30 companies since 2015 
  • Experience in international Business negotiations since 2015
  • Management Studies (M.Sc.) at the HHL Graduate School of Management, 2020

Various education and training courses, including

  • Negotiation Mastery (Harvard Business School Online) 
  • Group dynamics & group processes, communication with great impact, etc. 

Values that shape our cooperation

During my stay at Aarhus University in Denmark I got to know the Scandinavian leadership approach. This management style, which is characterised by a strong consensus orientation, has influenced my partnership with clients ever since.


Trust is the most important foundation for successful agreements. The same applies to our cooperation. Discretion and transparency are very important to me in order to build a strong basis of trust with you. In this way I would like to offer you a protected space for a fruitful cooperation.


My support may have a long-term effect and create change. I put quality before quantity and respond to the individual needs of people and their corporate environment.


Negotiating is my passion. I am convinced that there is a chance in every negotiation. I will support you with great drive. For me, the rule is all or nothing.


GOAL 4 – Quality Education:

“Ensure inclusive, equitable and quality education and promote opportunities for lifelong learning for all”.

I am a mentor in the “Job-Buddy Programme” initiative of Über den Tellerrand Frankfurt e.V. This 5-month sponsorship programme helps refugees find their dream job in Germany and gain a foothold in the German labour market.

GOAL 5 – Gender Equality:

“Achieving gender equality and empowering all women and girls for self-determination”.

With my coaching offer I directly support women in making themselves strong and stand up for their equality in their jobs. I help them to conduct salary negotiations and promotion talks at eye level and to demand what they are entitled to.

I am also a supporter of the current campaigns #stayonboard and #ichwill.

If you would like to learn more about the topic of gender equality in the German business world, I can recommend the publications of the AllBright Foundation.

GOAL 17 – Partnerships for the Goals 

“Strengthening means of implementation and revitalising the global partnership for sustainable development”.

Only together can we master the major challenges we face as a society. That is why I am committed to working in partnerships to achieve the UN sustainability goals.
