Jared Isaacman: The billionaire behind first private spacewalk

Polaris Dawn is not his first space mission. In 2021, he bankrolled and led the first private, all-civilian team to ever orbit the Earth.

That crew – named Inspiration4 – left on a SpaceX capsule from Florida and spent three days in space before splashing down successfully in the Atlantic Ocean.

Time magazine estimated that Mr Isaacman paid $200m (£153m) to fellow billionaire Elon Musk for all four seats aboard the SpaceX craft.

“That was a heck of a ride for us,” Mr Isaacman radioed shortly after landing at the time. “We’re just getting started.”

Born in Union, New Jersey, Mr Isaacman started his successful company Shift4 Payments from his parents’ basement, according to a report by Forbes.

The company now handles payments for a third of restaurants and hotels in the US, including big names like Hilton, Four Seasons, KFC and Arby’s.

He also founded Draken International in 2011, a defence firm that trains Air Force pilots and owns the world’s largest fleet of private military aircrafts.

In 2019, Mr Isaacman sold a majority stake in Draken to Blackstone, a Wall Street firm, for a nine-figure sum, Forbes reported.

The magazine dubbed him a “thrill seeker” in a 2020 profile, reporting that for fun, Mr Isaacman “bullets the MiG faster than the speed of sound and climbs mountains to unwind from non-stop, intense 80-plus-hour weeks”.

His brother, Michael Isaacman, told Forbes that the businessman is “a big believer that we all have a limited fatigue life, so let’s do the most amazing things that we can while we’re alive”.

Mr Isaacman and the others on board the Polaris Dawn are expected to return on Saturday.
