K-Cup billionaire sells Palm Beach waterfront mansion for just over $66M after steep price cut

K-Cup billionaire Robert Stiller sold his waterfront mansion in Palm Beach, Florida, for roughly $66.14 million, just a few years after snapping up the luxury estate.

Stiller — the founder of Green Mountain Coffee Roasters, which later acquired Keurig — bought the North Lake Way property in April 2023 for $66 million. The sprawling 13,300-square-foot estate hit the market in May with a lofty $90 million asking price, according to Mansion Global. 

The sale was confirmed by Christian Angle of Christian Angle Real Estate in a Dec. 30 Instagram post. Angle said he represented both the buyer and seller.
