On Dec. 9, LedgerX derivatives exchange CEO Paul Chou and his wife Juthica, the COO, were unceremoniously removed by the board of the company they founded. While no explanation was given, the company suffered a huge and embarrassing setback over the summer.

LedgerX may have placed its founders "on administrative leave," but they're still listed as the company's leaders on its website (via LedgerX).
