Blue Origin
By July 2014, Jeff Bezos had invested over into Blue Origin. By March 2016, the vast majority of funding to support technology development and operations at Blue Origin has come from Jeff Bezos' private investment, but Bezos had declined to publicly state the amount prior to 2017 when an annual amount was stated publicly – as of April 2017, Bezos was selling approximately in Amazon stock each year to privately finance Blue Origin.
