Funk will be the oldest person in history to fly into space, and Daemen will be the youngest. Funk previously trained as an astronaut during the 1960s, but was not selected to go to space.
Daemen will take the place of the anonymous winner of a $28 million auction for the first seat, who opted to take a later flight due to a scheduling conflict.
"This marks the beginning of commercial operations for New Shepard, and Oliver represents a new generation of people who will help us build a road to space."
Daemen, who will attend Utrectcht University in the Netherlands this fall, has a private pilot's license and is the son of hedge fund manager Joes Daemen.
Bezos announced in June that he will be on the inaugural flight.
Blue Origin's rocket is expected to travel to the Kármán line of 62 miles high, an international standard to define space.
