[1] He had started programming in 1983, at the age of eight, when he modified the dialog for a text adventure game, lending him an advantage in this field at school.

[2] In 1995, he abandoned his computer science degree and dropped out of college to establish ArrowWeb, a web hosting company, and later WebSite Machines, which developed multimedia and Internet software.

[2][3] Hagewood heavily invested in the Internet industry and operated his companies out of Satellite Beach, Florida, but faced great competition.

After the studio completed a demo and pitched it to potential publishers, it briefly experimented with adding vehicles to the 2002 game Unreal Tournament 2003, something Hagewood felt it had been lacking.

Hagewood informed him about the studio's more recent work, which it called VehicleMOD, and Rein asked to be shown a prototype at the Game Developers Conference in March 2003.

[5] Hagewood believed that working with Epic Games remotely from Florida would impact the mode's quality, so he relocated Psyonix to Raleigh, North Carolina, later in 2003.

[8] While Supersonic Acrobatic Rocket-Powered Battle-Cars broke even, it attracted fewer players than anticipated and did not bring about a significant profit, causing Psyonix to return to contract work.

[4] In December 2009, the studio and all of its employees moved from Raleigh to larger offices in San Diego, near the city's Gaslamp Quarter.

[9] Later contract projects included Whizzle (a tech demo for the Unreal Development Kit) and additional work on Bulletstorm, Homefront, Mass Effect 3, and XCOM: Enemy Unknown.

[4] Hagewood argued that Supersonic Acrobatic Rocket-Powered Battle-Cars was "too hardcore", leading to a change of pace for Rocket League.

Psyonix quickly expanded to 70 people by December 2016 and consequently moved to a larger office in the 1 Columbia Place tower, spanning 40,000 square feet (3,700 m2) across two floors.

[14][15] From his proceeds of the sale, Hagewood bought the Benetti Galaxy, a 56-metre (184 ft) superyacht, and intended to invest in space tourism.
