The Story

15 years of success and still counting...


Formation - 2007

Castle Hall begins serving its client base in January 2007. From the outset, Castle Hall offers clients robust segregation of duties, separating the governance, risk and compliance due diligence function from the advocacy role of investment decision making. Castle Hall has never managed assets, built portfolios, or sourced and recommended funds.


Our First Fraud - 2007

Conducting due diligence on Lakeshore, Castle Hall finds that the fund's administrator was relying on a daily email of trade data being sent to them by "trades@primebrokers.co.uk". The domain had been set up by the hedge fund's CFO. Investors lost more than $300 million - but thankfully not Castle Hall's client.


Hedge Fund Investing in a New World - 2008

In November 2008, Castle Hall publishes a white paper asking whether 2 and 20 is flawed, whether funds need better corporate governance, and questioning why fund offering documents protect the manager more than the investor. 10 years later.....


From Manhattan to Madoff - 2009

Castle Hall publishes a white paper analyzing the causes and lessons of hedge fund operational failure, considering more than 300 operational events in the hedge fund industry.


Due Diligence in Australia - 2011

Partnership with SwissAnalytics - 2014

Castle Hall and SwissAnalytics, based in Zurich, enter into a strategic partnership, which results in a full merger of activities in 2017. SwissAnalytics provides coverage for Castle Hall's European clients and also contributes the firm's risk due diligence methodology, which evolves to become RiskDiligence.
