We invest in companies and projects in the fields of infrastructure, renewable and conventional energy production, grids, raw materials projects, the health industry and numerous other sectors.
We also structure financing for our own projects and those of our clients.

We identify and negotiate projects for our own investments or on behalf of our clients. Whether industrial investment or infrastructure projects, solar power or petrochemical plant: We search for suitable project destinations, suppliers, customers and local partners, conduct negotiations on site and support in dealing with authorities.

In a complex geopolitical framework, it is becoming a decisive success factor for companies to reorganise their international presence and value chains in a way that the become resilient. Together with you, we develop a detailed plan for entering new sales markets or investment destinations. We analyse opportunities and risks in relevant countries and develop measures to actively manage and minimise them. We work closely with local stakeholders to explore project opportunities and deal with problems in a timely manner.

In complex negotiation situations, we accompany you or advise and coach the negotiators in the background.

Many companies have experienced difficulties due to the crisis and the international “shutdown” measures. Now a whole series of challenges are on the agenda at the same time. Reducing fix cost and financial restructuring on the one hand, and realising rapid sales success in already growing markets on the other, are key success factors. Together with you, we will develop action plans and support their implementation through our broad network.

Restructuring and reorganisation of businesses in the international market requires experienced personnel who are familiar with local environments. We identify qualified technical and management personnel and develop the selection process together with you in order to successfully fill the most important positions in your company.
