About Us

Aall & Co. Ltd. Aall originated as a trading, shipbroking and marine services company in Japan in 1904. The Monsen family assumed ownership in 1954. Over the past century Aall expanded into shipping related investments, real estate, and financial services. Aall Trust & Banking Corporation (AT&B), founded by Aall in the Cayman Islands in the 1970s, was sold to Cayman National Bank in 2004.

Headquartered in the Cayman Islands, Aall has ongoing relationships with investors and service providers in Japan, Europe and the United States. On behalf of the founding family and a select roster of clients, Aall actively co-invests with strategic partners within its fields of expertise.  Aall has a CIMA exempted license in the Cayman Islands which allows it to manage investments for sophisticated investors.



Aall holds legacy real estate assets globally which are considered passive, capital preservation positions.


Aall invests via private equity and credit across the spectrum of companies in their respective life cycle. This includes early stage technology enabled startups to lower middle market companies that are family run and operated with proven management teams and savvy operational acumen.


Aall’s public equity strategy consists long/short positions and the use of options to form a portfolio of publicly listed companies, Master Limited Partnerships, corporate debt, and preferred equities.


Aall invests in companies with proven management in the later stages of cash production. Aall’s representatives sit on the board of several of these companies to provide executive experience.
