Stenham has been active in investment management for over 25 years, although the Group’s origins date back to 1901 when Osias Stenham founded the company to act as buying agents for wholesale importers C Saloman of Southern Rhodesia. Stenham grew into a confirming house providing documentary credit facilities and trade finance to a wider group of clients in Africa.

Edwin Wulfsohn, now the Group's Deputy Chairman, joined Stenham in 1970 as its Chairman and Chief Executive and expanded its activities into a multi-family office offering trust services, wealth management and corporate finance/private equity services. With the growth of the hedge fund industry in the 1980’s, Stenham evolved its wealth management business into an investment manager specialising in multi-manager hedge fund portfolios, launching its first fund of hedge funds, Stenham Universal, in 1992. In the mid-1990s, a consortium, including members of the management team, purchased equity in the Group, thereby ensuring long-term succession with an experienced and multi-disciplinary team. The original two founding families continued as shareholders. In 2001, Stenham was acquired by BoE Limited, then South Africa's largest listed private bank and sixth-largest banking group. The following year BoE was itself acquired by Nedcor, a part of the Old Mutual Group and one of South Africa’s largest banking and insurance groups.

In October 2004, an opportunity arose for a private consortium to acquire Stenham from Nedcor. The consortium included all senior management and representatives of the original founding families of Stenham. In April 2008, Stenham formed a strategic alliance with Peregrine, listed on the Johannesburg Stock Exchange. Peregrine acquired a majority stake in Stenham with the former shareholders and additional members of management holding the balance. Peregrine is a leading provider of wealth and asset management solutions in South Africa; Sean Melnick, the founder of Peregrine, is Chairman of Stenham. Stenham currently employs c.100 staff, across 6 operating companies, in the Channel Islands and has had a presence since the late 1970’s.

Stenham Wealth Management (C.I.) Ltd was formed in 2016 with a view to expanding Stenham’s footprint in the Channel Islands and beyond.
