What do we stand for?

The future emerges where clarity, structure, and courage come together.

REINVENTIS stands for a conscious approach to development: analytically sound, creatively and pragmatically conceived, precisely implemented.

Our principles:

  • Clarity – Decisions become easier when the essentials become visible.
  • Value orientation – We don't design loudly, but substantively – with a view to long-term stability.
  • Responsibility – Mandates with significance deserve confidentiality, depth, and personal support.
  • Technology intelligence – For us, the strategic use of AI and technologies is not an end in itself, but rather a tool for future viability.
  • Reinvention – We continue to develop without recklessly abandoning what already exists.

Our philosophy

Reinvention, innovation, and transformation are more than just change.

It is a conscious decision to actively shape the future – regardless of whether it concerns a company, a brand, an organization, or real estate assets.

We believe that sustainable development can only succeed if three levels work together:

  1. Strategic clarity: Where do we want to go—and why?
  2. Benefit-based identity: Who are we—and what value do we create?
  3. Transformation & implementation: How do we shape change so that it is effective and sustainable?

This combination gives rise to the unmistakable signature style of REINVENTIS.

Who do we work for?

We provide real estate consulting and real estate asset management services to clients who value responsibility, discretion, and future security:

  • Private real estate asset owners
  • entrepreneurial families
  • Family offices
  • Ownership companies and asset managers
  • Portfolio decision-makers with a long-term horizon

Our work is discreet, personal and clearly structured – with a focus on sustainable value creation.

Our approach

For us, strategy consulting means:

  • personal support from experienced experts
  • Customized solution architectures instead of standard products
  • calm, focused collaboration for strategic decisions
  • Confidentiality in dealing with family and real estate assets
  • measurable impact as a benchmark

We work for those who take responsibility—for people, values, and the future.

Our voluntary commitment

Trust is built through responsibility—and we take that responsibility seriously.

Integrity is not an option for us—it is a matter of course. We are uncompromising in our commitment to high ethical standards and are exclusively dedicated to the interests of our clients.

Every decision and every action is taken in accordance with the jointly defined framework conditions – clear, transparent, and reliable.

In addition, we voluntarily adhere to the guidelines, recommendations, and quality standards of the Federal Association of German Management Consultants (BDU) e. V., Bonn, as well as the "Real Estate Investment Management" (REIM) code of conduct of the Society of Real Estate Research (gif) e. V., Wiesbaden.

These standards are not just guidelines for us, but an expression of our attitude.

Of course, we have also signed an anti-sect declaration.

And because values are only strong when they are shared, we also commit our key partners in cooperation to voluntarily follow the same principles.

Our commitment

Every year, we donate a significant portion of our profits to social and environmental initiatives in Munich, Germany, and around the world.

We thank our clients for their trust—it makes our work possible.

In return, we want to do our part to ensure that disadvantaged people also receive support and that our world remains livable.

Our stance

We support people who want to shape the future.

Not loud. Not hectic. But conscious, structured, and effective.

REINVENTIS stands for quality, depth, attitude—and for the conviction that continuous development is one of the most valuable decisions you can make.

Your next step

We would be happy to discuss your goals and vision for the future with you in person.
