Oliver Daemen (born 20 August 2002[citation needed]) is a Dutch space tourist[1][2] who flew as part of the 20 July 2021, sub-orbital Blue Origin NS-16 spaceflight.

[8][9] Oliver's father, Joes Daemen is a CEO of Somerset Capital Partners, a private equity firm in the Netherlands.

Olivers's space tourist seat on the New Shepard rocket was secured through an auction, making him Blue Origin's first customer (i.e. a person whose flight was not paid for by Blue Origin) and the 8th person to privately fund their non-professional spaceflight.

[10][11] Initially, cryptocurrency entrepreneur Justin Sun (who at the time remained anonymous)[12] won the auction with a $28 million bid for the one available seat on NS-16.

Oliver's father, Joes Daemen "had secured a seat on the second flight," said a Blue Origin spokesperson, and when Justin Sun backed out, Daemen's seat was "moved up,"[8][13][14][15] On 20 July 2021, Oliver at 18 became the youngest person to take sub-orbital first fully automated spaceflight with civilian passengers of approximately 10 minutes in duration reaching apogee 107 km (66 mi).
