The formation of the Olsson Eriksson fortune can be traced back to 1946, when Sten Allan Olsson bought his first vessel with a loan of $3000: The shipping business started on a small scale. In the 1960s Sten started a ferry service between Gothenburg and Skagen in northern Denmark. Over the years freight services using the company’s vessels became a significant part of the business. In 1972 the business was divided into two branches: Stena Line AB and Stena Metall AB. Over the years the company expanded its activities (e.g. real estate, drilling, private equity, etc.) to secure operations. Today Stena is mainly divided into Stena AB (ferry, drilling, shipping, ship construction, real estate, private equity, treasury) and Stena Metall AB (trading steel, metals and oil; recycling of metals, paper, electronics, hazardous waste and chemicals). With revenues of $4.2 billion and 16,000 employees, the Stena AB Group is one of Sweden’s largest family-owned corporate groups. The group is owned by Dan Sten (51%), Stefan Sten (24.5%) and Madeleine Olsson Eriksson (24.5%). In 2018 Formica Capital, the single family office of the Olsson Eriksson Family, was founded.

Proventus is the life’s work of Robert Weil, one of Sweden’s most unorthodox investors. In 1969 with only 20 years, he started his first investment company Weilinvest which would later be renamed to Proventus. He and his company were an active driver of the professionalisation, internationalisation and improvement of transparency of the Swedish capital market. As an investment company they acquired in their 50 years of existence various companies. After the acquisition of the companies, they reformed and optimized them, held them and sold them later. Notable examples are the Swedish toy company BRIO, later sold to Ravensburger. In another transaction Weil acquired Götabanken (one of the most important financial actors in the Swedish finance system) and later sold it to SPP, Sweden’s largest insurance company. They also did a restructured PUMA in 1990, replacing the management and restructuring the company to later sell their shares to an American Investor. Robert Weil has outspoken political views against nationalism, antisemitism and supports several Jewish organisations worldwide, also comments on politics in the most important newspaper in Sweden, Dagens Nyheter.

The company structure of Proventus as of today is twofold. One part is comprised of Proventus Capital Partners which is an alternative banking institution, providing loans between 10 million and 100 million to mid-sized companies who are not able to raise equity for expansions and acquisitions. They invest in all sectors without a specific industry focus. Northern countries like Scandinavia, the British Isles and Germany are core countries for Soventus Capital Partners. The capital to make these investments comes from 5 funds which received capital from various pension funds and the mother company Proventus AB. The strategy is to provide a tool tackling deficits in the financial sector, where companies are left without adequate access to classical financial institutions and loans. The four funds combined comprise of capital around 20 billion euros for direct lending.

The second smaller branch is called Proventus Invest and operates in two ways. One branch of Proventus Invest operates as a hedge fund, doing opportunistic investments in mispriced companies in order to sell them in the short-medium term with a bonus. Second, the company focuses on longer-term investments in companies or asset around the Nordic region.
