Wallbrook is a global risk management consultancy which specialises in integrity and compliance diligence, strategic and business intelligence, deal compliance advisory, and market and sector entry. We help our clients navigate the risks they face when entering and operating in developed and emerging markets or with unfamiliar counterparties.

Our professionals are based in offices in London, Dubai, Hong Kong, New York and Zurich, and have a long track record in this sector, having worked closely together since 2007. Prior to work in risk management our staff have often had varied careers in the law, in-house compliance, journalism, government and academia. Their backgrounds, professionalism and rigorous approach to understanding and melding open source and human intelligence allow us to quickly assess, contextualise and advise on relationships that may cause our clients regulatory or reputational harm.


The history of the team at Wallbrook dates back to Billiter, a due diligence consultancy founded in 2007. Many of Wallbrook’s founding Partners and Directors worked at Billiter together prior to selling the company to US investigations firm Stroz Friedberg in 2013. They subsequently developed the Due Diligence & Strategic Research group of Stroz Friedberg and were part of the management team which oversaw the acquisition and integration of Stroz Friedberg into Aon Plc (NYSE: AON) in 2016.

In 2018, many of the team reformed as Wallbrook to create what is already one of the largest independent and wholly employee-owned due diligence firms in the sector.
