Entrepreneurial organization

Stronghold was built by entrepreneurs and has continued to be an entrepreneurial organization. Working at Stronghold you should strive to be innovative and creative at all times.

That’s why we work hard to decentralize decision making – which enables our employees to act rapidly and execute on new business opportunities.

The entrepreneurial spirit and decentralized decision making are promoted in all our companies.

Our strategy combines an accelerated organic growth, supported by acquisitions within strategic areas and starting new businesses in collaboration with our experienced professionals at Stronghold.

Our core values passion for colleagues and clients – in that order – are vital to our growth strategy. We see our employees as our greatest assets, which is why we proactively invest to provide a challenging and rewarding environment to grow from.

To support our companies in meeting the challenges and exploiting the opportunities from the digital transformation, currently taking place in the global real estate industry, Stronghold has established a new business area, Proptech, with the objective to ensure that the Stronghold Group is at the forefront of digital technology.

What we believe in

‘Passion for Colleagues and Clients’ is the basis for our philosophy and attitude to one another and our clients. Passion presumes commitment, which in turn demands the desire and the ability to listen to the client and each other; to be interested in, and have respect for, colleagues’ and clients’ needs and issues; to take initiatives; to preserve and to deliver what we promise.

We choose not to work with everyone. Our values determine our way of working, cooperating and investing. No matter whether you are a colleague or client, our core values – ‘Excellence’, ‘Innovation’ and ‘Integrity’ – need to be recognized.

Excellence is the desire and the ability to deliver solutions and services of the highest quality – exceeding both the client’s highest expectations and the best capabilities of our competitors.

Innovation is the desire and the ability to seek, identify, and implement new solutions; to lead the development of new services and products – to have the courage to break with tradition.

Integrity is the ability to ensure that every client’s confidentiality is respected and that every task is undertaken with the client’s best interests in mind – at all times with the highest business ethics and morals.

If we can create a culture where all our employees are satisfied, and where they know that their contribution is appreciated, then client focus will follow naturally. This is why we put great emphasis on employee development. Stronghold University – our approach to learning and building competence – lets us continuously analyze, define, build and evaluate the skills necessary to develop our employees.

Business Principles

The success of the Stronghold Group does not solely depend on the quality of the work we carry out for our clients. It is at least as important that we build and maintain an acknowledged reputation regarding business morals and correct ethical conduct.

This naturally applies to contacts both inside and outside the Group. It allows for more trust and confidence, and means that we can work in an open and non-bureaucratic atmosphere.

To guide and inspire, our Business Principles helps us navigate and to ensure that we have a common view on business moral and ethics.

Social value

Many companies take pride in contributing to the creation of social values, over and above their regular business. For companies in the Stronghold Group it comes naturally to be an active community builder in the cities we operate in and to contribute to those cities’ attractiveness. Cities are a breeding ground for creativity, innovation, entrepreneurship and GDP growth, essentials for a thriving economy.

Our mission stems from many years of witnessing the close relationship between a city’s prosperity and property returns. A study carried out by Newsec in 2014 concluded that as much as 70 percent of the total property return can be explained by the GDP growth.

“We Love Cities” represents our view on success factors for developing attractive cities and how Stronghold Group contributes to these factors.
