Tokyo Sexwale has announced that he is stepping down as chairman of Trillian, and Thursday is his last day on the job.
Sexwale says one family and allegations of state capture are destroying his organisation.
He says one group of people have had control over the country.
The businessman is briefing media on the Geoff Budlender's report into Trillian and alleged links to the controversial business family, the Guptas.
Sexwale has urged people not wait to get caught through incriminating emails but to rather come out with information on state capture.
He adds that he knows the Guptas are good people, but maybe there is something he doesn’t know.
Sexwale says emails exposed in the Gupta leaks have shocked him.
