Executive Sparring Brain Orchestra

Flexible online sparring by highly experienced managers

Executive Sparring

Today, it is more important than ever that decision-makers can assess the right information with the right experience at the right time. A second opinion, analysing political situations, reflecting and complementing each other are typical sparring situations for us. The aim of Brain Orchestra is to bring clients and experiences together quickly and easily online. In a bilateral conversation, topics can be elicited in small time units and if necessary, we can put together an Orchestra.

Brain Orchestra supports decision-makers & executives as a sparring partner exactly when they need us.

Brain Partner Markus Hoischen
Markus Hoischen

The determination after the decision drives me to think in a new way, to work differently, to act effectively with respect for the other person. Authentic, creative and empathic, I work with and for people in the situations that move them. My claim is to fulfil what I promise. How do I achieve this? If you always talk, you cannot listen to the other person. We have two ears and one mouth. I use those proportionately.

Experiences of our customers in sparring with Brain Partners

Dr. Stefan Borsutzky

CEO, Otto Group Solution Provider

Experience in small time units

Brain Orchestra manages to make people's experiences available ad hoc and transparently to other organizations. It will finally close the gap to buy experience in smaller time units. In executive sparring with Markus Hoischen, it was always enriching to gain new impulses and food for thought for the further development of the organization.

Uwe Kolk

CIO, Jungheinrich AG

Catalyst & Implementer

In more than 30 years of IT management, I have gained predominantly bad experiences with external, interim support. Sales-strong organizations, weak content or self-proclaimed experts do not understand much about many things. Brain Ochestra focuses on empowering people to solve upcoming tasks. Whether catalyst or implementer, Brain Orchestra puts effective levers in the hands of the customer.

Hans Ulrich Remfert

former CEO Revell

New impulses and food for thought

Brain Orchestra has successfully advised Revell GmbH &Co.KG on the structuring and implementation of internal processes over a longer period of time. We have come to appreciate Brain Orchestra in the person of Markus Hoischen as very competent and practice-oriented. The cooperation was extremely trusting and goal-oriented. I myself have been able to find interesting impulses and food for thought in direct sparring.

Maximilian Brandl


Excellent cooperation

A very trusting, extremely professional and content-wise excellent cooperation - as with an excellent own employee - gladly again at any time.

Dirk Giesguth

CEO, Giesguth mbH, MeinMassivholz

Convince with implementation strength

Brain Orchestra is fresh, thinks outside the box and convinces with its balance of experience, knowledge and implementation strength. The flexibility and the exchange in direct sparring help me to implement the new paths consistently and reflectively.

Typical sparring situations

We support you with individual sparring offers in numerous subject areas. Brain Partners are a reliable sparring partner in various situations.

Executive Sparring

When it gets political

  • How should I present myself to the shareholder?
  • How do I formulate my answers for the Supervisory Board?
  • How do I deal with possible layoffs?
  • What strategic alternatives do I have to achieve my goal?


If a second opinion is needed

  • Is the document prepared for the supervisory board correct?
  • Can I still strengthen my arguments for the investment decision?
  • Is my decision to change technology the right one?
  • Is the budget I set for you enough?


When it burns

  • Can you make me a presentation about the Budget 2020?
  • Can you guide the SAP implementation?
  • Can you improve these documents with clear examples?
  • Can you make a proposal for the IT project organization?


When prompt expertise is required

  • What does digital transformation actually mean?
  • What are the alternatives to organizational development?
  • How do I set up an IT project correctly?
