The £1bn property venture, aAim Capital Finance, is backed by Middle Eastern investors and is looking to profit from the suppressed property market by picking up real estate assets at rock-bottom prices.
Frost will be the firm's deputy chairman and Ferguson is a major shareholder.
The firm, which was described by Frost as a 'new dawn in the property sector', was launched this month in a flurry of publicity.
The new venture was covered in the Financial Times, the Daily Express and Scotland on Sunday, as well as by Bloomberg, Reuters and the specialist financial media.
The investment company was created from the ashes of fund manager aAim Ltd, now called JCCO 114, part of the aAim Group that fell into administration last year after Bank of Scotland withdrew its funding.
Frost and Ferguson are expected to drum up support for the firm with a roadshow.
