I know of Windings: "an Employee Stock Ownership Plan (ESOP) is a legal business structure that utilizes shares ... ESOP shares are only available to employees of the company"
> In 1998, as part of Ryberg’s retirement strategy, Windings Inc. formed an Employee Stock Ownership Plan (ESOP) for a planned purchase and transition of Company stock to the Windings employees. Ryberg retired in 2006, and by 2008 the company became 100-percent employee-owned.
