The Onyx ethos of know and trust was developed by David Sapseid and Frank Hawkins in 1998 when Onyx Management Ltd was formed in the Isle of Man. They were joined by Joe Plastow in 2000. All had been employed by subsidiaries of the Johannesburg Stock Exchange-listed Safmarine and Rennies Holdings (Safren).


The business became licensed as a Trust and Corporate Service Provider when the sector was regulated by the Isle of Man CSP Act 2000. Onyx evolved from a fiduciary for high net worth clients to an investment holding company holding stakes in operating companies.

The regulated fiduciary business of Onyx was sold to Baker Tilly in 2016 and the Group has since focused on its private equity, corporate finance and investment activities. Attracted by David's ethos and vision, experienced executives have joined the team in the UK, South Africa and Australia.
